I know this question is posted many times but truly i didn't get any suggestion that can solve my problem. I wasted my two days on this problem but till now i didn't get any solutions. Please give your valuable guidance.
I want to post status on Facebook.
if ([PostType isEqual:#"article"])
{
[dict setObject:PostTitle forKey:#"message"];
params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
PostTitle, #"message", nil];
if (FBSession.activeSession.isOpen) {
// Yes, we are open, so lets make a request for user details so we can get the user name.
if ([[[FBSession activeSession] permissions]indexOfObject:#"publish_actions"] == NSNotFound) {
[[FBSession activeSession] requestNewPublishPermissions:[NSArray arrayWithObjects: #"publish_actions",nil] defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session,NSError *error){
[self promptUserWithAccountName];
}];
}else{
[self promptUserWithAccountName];
}
// a custom method - see below:
} else {
NSArray *permissions = [[NSArray alloc] initWithObjects:
#"publish_actions",
nil];
// OPEN Session!
[FBSession openActiveSessionWithPermissions:permissions
allowLoginUI:YES
completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// if login fails for any reason, we alert
if (error) {
// show error to user.
} else if (FB_ISSESSIONOPENWITHSTATE(status)) {
// no error, so we proceed with requesting user details of current facebook session.
[self promptUserWithAccountName]; // a custom method - see below:
}
}];
}
Custom method:
-(void)promptUserWithAccountName {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (!error) {
[FBRequestConnection startWithGraphPath:#"me/feed"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error){
if (!error) {
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:#"Success"
message:#"Photo Uploaded"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"Ok", nil];
[tmp show];
} else {
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:#"Error"
message:#"Some error happened"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"Ok", nil];
[tmp show];
}
}];
}
}];

I'm trying to check if the current user has verified it's email before
they proceed to the next step. What am i doing wrong please help thank you. The phone number saving in background works.. When i call on the "SavePhoneInBackground" the app crashes
(The SVProgressHUd is the activity indicator)
-(void) SavePhoneInBackground {
PFUser *user = [PFUser currentUser];
user[#"phone"] = _phone_register.text;
[user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (!error) {
NSLog(#"PhoneUpdatingSucces!");
_phone_register.text = nil;
[self checkUserEmailVerify];
}else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Whoops!" message:#"Something went wrong! Try again." delegate:nil cancelButtonTitle:#"ok" otherButtonTitles:nil];
[alert show];
[SVProgressHUD dismiss];
NSLog(#"There was an error in the registration!");
}
}];
}
-(void) checkUserEmailVerify {
PFUser *user = [PFUser currentUser];
if (![[user objectForKey:#"emailVerified"] boolValue]) {
// Refresh to make sure the user did not recently verify
[user refresh];
if (![[user objectForKey:#"emailVerified"] boolValue]) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Whoops!" message:#"You need to verify your emailadress!" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
return;
[SVProgressHUD dismiss];
}
}
// This is a triumph.
[SVProgressHUD dismiss];
[self performSegueWithIdentifier:#"login2" sender:self];
}
func giveCaketoUser(user: PFUser) {
if (user.objectForKey("emailVerified").boolValue == true){
println("true")
} else {
println("flase")
}
}
Here is something I used in one of my recent projects:
- (BOOL)validateEmail:(NSString *)emailStr {
NSString *emailRegex = #"[A-Z0-9a-z._%+-]+#[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:#"SELF MATCHES %#", emailRegex];
return [emailTest evaluateWithObject:emailStr];
}
There are other manipulations of the regex you can use. When I used this method the problem I had was that the project would continue to register the user while still showing my custom alert and NSLog error, but that may have been failure on my end and not the method.
Hope this will send you down the right direction!
This is how I did it in my App and it will only let verified email users to access. You will need to modify it slightly for what you want.
- (void)logInViewController:(MyLogInViewController *)logInController didLogInUser:(PFUser *)user {
if (![[user objectForKey:#"emailVerified"] boolValue]){
NSLog(#"User not validated email");
[[[UIAlertView alloc] initWithTitle:#"Access restricted" message:#"To access this area please validate your email address" delegate:nil cancelButtonTitle:#"ok" otherButtonTitles:nil] show];
}
else if ([[user objectForKey:#"emailVerified"] boolValue]){
NSLog(#"Email validated");
[self dismissViewControllerAnimated:YES completion:NULL];
[[[UIAlertView alloc] initWithTitle:#"Welcome back" message:(#"%#", user.username) delegate:nil cancelButtonTitle:#"ok" otherButtonTitles:nil] show];
}
// [self dismissViewControllerAnimated:YES completion:NULL];
NSLog(#"Login sucessfull and username is %#",user.username);
}
Hope this helps if you have not worked it out yet!
hi i want to integrate Via Me social site into my iphone app,i googled but didn't find any samples.
The basic process is as follows:
Create a custom URL scheme for your app. Via Me will use this after the user has been authenticated, to return to your app. In my example, I created one called "robviame://"
Register your app at http://via.me/developers. This will give you a client id and a client secret:
When you want to authenticate the user, you call:
NSString *redirectUri = [[self redirectURI] stringByAddingPercentEscapesForURLParameterUsingEncoding:NSUTF8StringEncoding];
NSString *urlString = [NSString stringWithFormat:#"https://api.via.me/oauth/authorize/?client_id=%#&redirect_uri=%#&response_type=code", kClientID, redirectUri];
NSURL *url = [NSURL URLWithString:urlString];
[[UIApplication sharedApplication] openURL:url];
What that will do is fire up your web browser and give the user a chance to log on and grant permissions to your app. When user finishes that process, because you've defined your custom URL scheme, it will call the following method in your app delegate:
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
// do whatever you want here to parse the code provided back to the app
}
for example, I'll call a handler for my Via Me response:
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
ViaMeManager *viaMeManager = [ViaMeManager sharedManager];
if ([[url host] isEqualToString:viaMeManager.host])
{
[viaMeManager handleViaMeResponse:[self parseQueryString:[url query]]];
return YES;
}
return NO;
}
// convert the query string into a dictionary
- (NSDictionary *)parseQueryString:(NSString *)query
{
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
NSArray *queryParameters = [query componentsSeparatedByString:#"&"];
for (NSString *queryParameter in queryParameters) {
NSArray *elements = [queryParameter componentsSeparatedByString:#"="];
NSString *key = [elements[0] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *value = [elements[1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
value = [[value componentsSeparatedByString:#"+"] componentsJoinedByString:#" "];
[dictionary setObject:value forKey:key];
}
return dictionary;
}
That handler might, for example, save the code and then request the access token:
- (void)handleViaMeResponse:(NSDictionary *)parameters
{
self.code = parameters[#"code"];
if (self.code)
{
// save the code
[[NSUserDefaults standardUserDefaults] setValue:self.code forKey:kViaMeUserDefaultKeyCode];
[[NSUserDefaults standardUserDefaults] synchronize];
// now let's authenticate the user and get an access key
[self requestToken];
}
else
{
NSLog(#"%s: parameters = %#", __FUNCTION__, parameters);
NSString *errorCode = parameters[#"error"];
if ([errorCode isEqualToString:#"access_denied"])
{
[[[UIAlertView alloc] initWithTitle:nil
message:#"Via Me functions will not be enabled because you did not authorize this app"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil] show];
}
else
{
[[[UIAlertView alloc] initWithTitle:nil
message:#"Unknown Via Me authorization error"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil] show];
}
}
}
and the code to retrieve the token might look like:
- (void)requestToken
{
NSURL *url = [NSURL URLWithString:#"https://api.via.me/oauth/access_token"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
NSDictionary *paramsDictionary = #{#"client_id" : kClientID,
#"client_secret" : kClientSecret,
#"grant_type" : #"authorization_code",
#"redirect_uri" : [self redirectURI],
#"code" : self.code,
#"response_type" : #"token"
};
NSMutableArray *paramsArray = [NSMutableArray array];
[paramsDictionary enumerateKeysAndObjectsUsingBlock:^(NSString *key, NSString *obj, BOOL *stop) {
[paramsArray addObject:[NSString stringWithFormat:#"%#=%#", key, [obj stringByAddingPercentEscapesForURLParameterUsingEncoding:NSUTF8StringEncoding]]];
}];
NSData *paramsData = [[paramsArray componentsJoinedByString:#"&"] dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:paramsData];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if (error)
{
NSLog(#"%s: NSURLConnection error = %#", __FUNCTION__, error);
return;
}
NSError *parseError;
id results = [NSJSONSerialization JSONObjectWithData:data options:0 error:&parseError];
if (parseError)
{
NSLog(#"%s: NSJSONSerialization error = %#", __FUNCTION__, parseError);
return;
}
self.accessToken = results[#"access_token"];
if (self.accessToken)
{
[[NSUserDefaults standardUserDefaults] setValue:self.accessToken forKey:kViaMeUserDefaultKeyAccessToken];
[[NSUserDefaults standardUserDefaults] synchronize];
}
}];
}
Hopefully this will be enough to get you going. This is described in greater detail at the http://via.me/developers page.
I am using FBFriendPickerViewController to load friends after user signs in. However, an empty table view is being loaded. The friends of the user from fb are not showing up.
Heres the code.
- (IBAction)inviteButtonTouchHandler:(id)sender {
if (!_friendPickerController) {
_friendPickerController = [[FBFriendPickerViewController alloc] initWithNibName:nil bundle:nil];
_friendPickerController.delegate = self;
_friendPickerController.title = #"Select friends";
_friendPickerController.allowsMultipleSelection = NO;
}
[_friendPickerController clearSelection];
[_friendPickerController loadData];
[self presentViewController:_friendPickerController animated:YES completion:nil];
}
This code is called after login which is done like this in appDelegate following the Facebook Tutorial -
- (void)openSession
{
NSArray *permissions = #[#"friends_about_me"];
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:
^(FBSession *session,
FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
}
You need to add the following code in viewDidLoad method of your viewController.
if (!FBSession.activeSession.isOpen) {
// if the session is closed, then we open it here, and establish a handler for state changes
[FBSession.activeSession openWithCompletionHandler:^(FBSession *session,
FBSessionState state,
NSError *error) {
switch (state) {
case FBSessionStateClosedLoginFailed:
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
break;
default:
break;
}
}];
}
I want to know how to post a status message to Facebook on iOS 6 using the new frameworks on Xcode 4.5. Thanks! :)
Posting a message is rather simple. It's almost like with the Twitter Framework.
First you have to import the Frameworks: Social and Accounts
#import <Social/Social.h>
#import <Accounts/Accounts.h>
In your .h file:
SLComposeViewController *mySLComposerSheet;
This code has to be included inside your action in your .m file:
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) //check if Facebook Account is linked
{
mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; //Tell him with what social platform to use it, e.g. facebook or twitter
[mySLComposerSheet setInitialText:[NSString stringWithFormat:#"Test",mySLComposerSheet.serviceType]]; //the message you want to post
[mySLComposerSheet addImage:yourimage]; //an image you could post
//for more instance methods, go here: https://developer.apple.com/documentation/social/slcomposeviewcontroller#//apple_ref/doc/uid/TP40012205
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = #"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = #"Post Successful";
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Facebook" message:output delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}];
And what do I have to do, when I just want to receive an alert in case the post was successful, and nothing when the user cancelled the post?
And unfortunately this does not work properly for Twitter... It doesn't dismiss the TweetSheet anymore. Here is my code:
if(NSClassFromString(#"SLComposeViewController") != nil)
{
mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; //Tell him with what social plattform to use it, e.g. facebook or twitter
[mySLComposerSheet setInitialText:[NSString stringWithFormat:story.title,mySLComposerSheet.serviceType]]; //the message you want to post
[mySLComposerSheet addURL:[NSURL URLWithString:story.link]];
//for more instance methodes, go here:https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Reference/SLComposeViewController_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40012205
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = NSLocalizedStringFromTable(#"As it seems you didn't want to post to Twitter", #"ATLocalizable", #"");
break;
case SLComposeViewControllerResultDone:
output = NSLocalizedStringFromTable(#"You successfully posted to Twitter", #"ATLocalizable", #"");
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Twitter" message:output delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
- (IBAction)btn_facebook:(id)sender {
SLComposeViewController *facebookcomposer =
[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[facebookcomposer setInitialText:#"This is just a test"];
[facebookcomposer addURL:[NSURL URLWithString:#"http://www.google.com"]];
[facebookcomposer addImage:[UIImage imageNamed:#"images.jpg"]];
[self presentViewController:facebookcomposer animated:YES completion:nil];
[facebookcomposer setCompletionHandler:^(SLComposeViewControllerResult result)
{
switch (result)
{
case SLComposeViewControllerResultDone:
NSLog(#"done");
break;
case SLComposeViewControllerResultCancelled:
NSLog(#"cancelled");
break;
default:
break;
}
}];
}
- (IBAction)btn_twitter:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {
SLComposeViewController *twitter =
[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[twitter setInitialText:#"this is just a test"];
[twitter addURL:[NSURL URLWithString:#"http://www.google.com"]];
[twitter addImage:[UIImage imageNamed:#"images.jpg"]];
[self presentViewController:twitter animated:YES completion:nil];
} else {
NSLog(#"it is not configured");
}
}
Ok guys, so I tweaked the original post, works for iOS 6/7. Change ServiceType, Alert Title and Message for Facebook. Enjoy!
- (IBAction)tweetMessage:(id)sender {
if(![SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) //check if Facebook Account is linked
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Unable to Tweet!" message:#"Please login to Twitter in your device settings." delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
return;
}
//self.mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
self.mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[self.mySLComposerSheet setInitialText:[NSString stringWithFormat:#"I found this Thing, check it out at this Place:\n %# \n", [self someplace]]];
[self.mySLComposerSheet addImage:self.photos.firstObject];
[self presentViewController:self.mySLComposerSheet animated:YES completion:nil];
//}
[self.mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = #"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = #"Post Successfull";
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Twitter" message:output delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}];
}
This is how I actually use it in my app though. Smoother and lets the controller do the hard work.
- (IBAction)postToFacebook:(id)sender {
if(![SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
NSLog(#"log output of your choice here");
}
// Facebook may not be available but the SLComposeViewController will handle the error for us.
self.mySLComposerSheet = [[SLComposeViewController alloc] init];
self.mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[self.mySLComposerSheet setInitialText:[NSString stringWithFormat:#"I found this Thing, check it out at SomeWhere:\n %# \n", [self someURLString]]];
[self.mySLComposerSheet addImage:self.photos.firstObject]; //an image you could post
[self presentViewController:self.mySLComposerSheet animated:YES completion:nil];
[self.mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = #"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = #"Post Successfull";
break;
default:
break;
}
if (![output isEqualToString:#"Action Cancelled"]) {
// Only alert if the post was a success. Or not! Up to you.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Facebook" message:output delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}
}];
}
I am trying to publish on Facebook using openActiveSessionWithPublishPermissions , so if the user is not logged in he need's to first sign in and then post the message using io6 Facebook native Dialog.
What I found is I am able to login, but completion handler is not called.
Another thing I noticed, that when I click the login button again, it then calls completion handler with the following error FBSessionStateClosedLoginFailed.
I did refer to this post but still did not find a solution to my problem.
NSArray *permissions = [NSArray arrayWithObjects:#"publish_stream", nil];
[FBSession openActiveSessionWithPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceEveryone allowLoginUI:YES completionHandler:
^(FBSession *session, FBSessionState status, NSError *error)
{
switch (status) {
case FBSessionStateOpen:
{
[FBNativeDialogs presentShareDialogModallyFrom:currentController initialText:nil image:nil url:nil handler:^(FBNativeDialogResult result, NSError *error) {}];
}
break;
default:
break;
}
}];
Make sure you implemented the handleOpenUrl method.
-(BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [[FBSession activeSession] handleOpenURL:url];
}
You should have to add this:
[FBNativeDialogs presentShareDialogModallyFrom:currentController initialText:nil
image:nil url:nil handler:^(FBNativeDialogResult result, NSError *error) {
if (result==FBNativeDialogResultCancelled) {
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"Error"
message:#"Sending Cancelled" delegate:self cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[alert show];
} else if (result==FBNativeDialogResultSucceeded) {
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"Succeed"
message:#"succeed" delegate:self cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[alert show];
}***}***];
