What can I do to use as an alternative to publish_actions? I have a photo app that lets users share their photos to their profile. Currently it uses logInWithPublishPermissions:#[#"publish_actions"] and then shares the files through FBSDKSharePhoto. But after August 1 this will be removed. Any thoughts? This is my current code but soon it won't work.
-(IBAction)loginToFacebook:(id)sender
{
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior = FBSDKLoginBehaviorWeb;
[login logInWithPublishPermissions:#[#"publish_actions"]
fromViewController:self
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
NSLog(#"Process error");
} else if (result.isCancelled) {
NSLog(#"Cancelled");
nonpressTimer = [NSTimer scheduledTimerWithTimeInterval:15.0 target:self selector:#selector(timeout) userInfo:nil repeats:NO];
} else {
NSLog(#"Logged in");
[self shareSegmentWithFacebookComposer];
}
}];
}
- (void)shareBoothOnFacebook {
NSUserDefaults *defaults2 = [NSUserDefaults standardUserDefaults];
NSData *data6 = [defaults2 objectForKey:#"layoutphoto"];
UIImage *myImage = [NSKeyedUnarchiver unarchiveObjectWithData:data6];
NSMutableArray *photos = [[NSMutableArray alloc] init];
for (int i = 0; i < [self.arrSlidshowImg count]; i++) {
UIImage *image = [UIImage imageWithData:[_arrSlidshowImg objectAtIndex:i]];
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = image;
photo.userGenerated = YES;
[photos addObject:photo];
}
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = [photos copy];
[FBSDKShareAPI shareWithContent:content delegate:nil];
}
}
You'll need to switch to using Facebook's iOS sharing APIs which require that the Facebook Messenger app is installed. See their documentation on sharing.
You might also want to investigate the use of the iOS share sheet but that also requires the Facebook Messenger app to be installed to enable sharing to Facebook.

I have been trying to figure this issue out for days now with no luck, any advice would be greatly appreciated.
I have a uitableviewcontroller that loads data from core data. When the tableview loads, the first 6 (no matter how many objects are actually saved) are loaded. When I begin to scroll down, all of the following cells are labeled "(null)". When I go back up to the top, the data in the original 6 cells are replaced with "(null)". When I logged the contents of the array from the fetch, all of the objects from core data get logged, but when I log the contents of the cell, the first 6 contents get logged, the a long list of rows with (null) get logged.
I've tried a lot of differnet things to debug this, but nothing has worked so far.
Here is the tableviewcontroller file
-(void)viewWillAppear:(BOOL)animated

Well maybe this is your problem.
if ([self.search isEqual:#0]){
I think you are initially fetching the data but than once you init the searchController it starts looking for the searchResults.
The code you are looking is:
if ([self.search isActive]){
I found the solution. I changed
AppDelegate *del = [[AppDelegate alloc] init];
NSManagedObjectContext *context = del.managedObjectContext;
to
AppDelegate *del = [[UIApplication sharedApplication] delegate];
NSManagedObjectContext *context =[del managedObjectContext];
and it works perfectly.
How to upload using AFNetworking in ios app extension?
apple's example uses NSURLSession, can you explain to me how this works?
- (void)didSelectPost {
NSExtensionItem *imageItem = [self.extensionContext.inputItems lastObject];
// Verify that we have a valid NSExtensionItem
if (!imageItem) {
return;
}
// Verify that we have a valid NSItemProvider
NSItemProvider *imageItemProvider = [[imageItem attachments] firstObject];
if (!imageItemProvider) {
return;
}
// Look for an image inside the NSItemProvider
if ([imageItemProvider hasItemConformingToTypeIdentifier:(NSString *)kUTTypeImage]) {
[imageItemProvider loadItemForTypeIdentifier:(NSString *)kUTTypeImage options:nil completionHandler:^(id item, NSError *error) {
if (item)
{
NSData *data = [NSData dataWithContentsOfURL:item];
[self method:data];
}
[self.extensionContext completeRequestReturningItems:nil completionHandler:nil];
}];
}
}
How do I upload this data using this method or using AFNetworking or using my app to upload this?
- (void)method:(NSData *)data
{
NSString *confName = #"com.example.photoblog.backgroundconfiguration";
NSURLSessionConfiguration *conf = [NSURLSessionConfiguration backgroundSessionConfiguration:confName];
NSURLSession *session = [NSURLSession sessionWithConfiguration:conf delegate:self delegateQueue:nil];
NSURLRequest *requeust = [self requestForExtensionItems];
NSURLSessionUploadTask *upload = [session uploadTaskWithStreamedRequeust:request];
[upload resume];
}
You should setting app group both Your extension and containing app,then config session like this
config.sharedContainerIdentifier = #"group.xxxxx";

I am developing an application which need to display photos from Picasa web album.
I have search about it. I got following links.
https://code.google.com/p/gdata-objectivec-client/
I have downloaded GData and also included all required folder into xcode.
The code which i have written is here.
- (void) loadPhotoGallery{
username = #"xyz";
password = #"abc";
GDataServiceGooglePhotos *photosService;
photosService = [self photoService];
NSURL *url = [GDataServiceGooglePhotos photoFeedURLForUserID:#"user" albumID:#"ablumID" albumName:nil photoID:nil kind:nil access:nil];
GDataQueryGooglePhotos *introspectQuery;
introspectQuery = [GDataQueryGooglePhotos photoQueryWithFeedURL:url];
[introspectQuery setResultFormat:kGDataQueryResultServiceDocument];
GDataServiceTicket *ticket;
ticket = [photosService fetchFeedWithQuery:introspectQuery delegate:self didFinishSelector:#selector(introspectTicket:finishedWithServiceDocument:error:)];
}
- (void)introspectTicket:(GDataServiceTicket *)ticket
finishedWithServiceDocument:(GDataAtomServiceDocument *)serviceDoc
error:(NSError *)error {
if (error == nil) {
GDataAtomCollection *collection = [[serviceDoc primaryWorkspace] primaryCollection];
NSArray *theMIMETypes = [collection serviceAcceptStrings];
}
}
-(GDataServiceGooglePhotos *)photoService{
static GDataServiceGooglePhotos *service = nil;
username = #"xyz";
password = #"abc";
if (!service) {
service = [[GDataServiceGooglePhotos alloc] init];
[service setShouldCacheDatedData:YES];
[service setServiceShouldFollowNextLinks:YES];
[service setIsServiceRetryEnabled:YES];
}
if ([username length] > 0 && [password length] > 0) {
[service setUserCredentialsWithUsername:username
password:password];
} else {
// fetch unauthenticated
[service setUserCredentialsWithUsername:nil
password:nil];
}
return service;
}
But i am very confused with this code.
Can anyone help. how to start code for fetching photos?
Thanks in advance.
I have resolve this. I have make two changes.
1. Edit loadPhotoGallery method
2. Create new method for fetching photos and displayed into grid.
My code for loadPhotoGallery is following.
- (void) loadPhotoGallery{
NSLog(#"fetchAllPhotos");
GDataServiceGooglePhotos *service = [self photoService];
GDataServiceTicket *ticket;
NSURL *feedURL = [GDataServiceGooglePhotos photoFeedURLForUserID:#"xyz#gmail.com" albumID:#"12345" albumName:nil photoID:nil kind:nil access:nil];
ticket = [service fetchFeedWithURL:feedURL delegate:self didFinishSelector:#selector(photosListTicket:finishedWithFeed:error:)];
feedURL = nil;
}
And code for displaying Photos into Grid is following.
-(void)displayGrid{
int x =0 ,y =0, counter =1;
for (int i=0; i<[self.photos count]; i++) {
GDataEntryPhoto *photoAlbum = [self.photos objectAtIndex:i];
GDataTextConstruct *textConstruct = [photoAlbum title];
NSString *stringTitle = [textConstruct stringValue];
NSLog(#"%#",stringTitle);
GDataMediaGroup *mediaGroup = [photoAlbum mediaGroup];
NSArray *arrMediaThumbs = [mediaGroup mediaThumbnails];
GDataMediaThumbnail *mediaThumbnail =[arrMediaThumbs objectAtIndex:2];
NSLog(#"%#", [mediaThumbnail URLString]);
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:[mediaThumbnail URLString]]];
UIImage *img = [UIImage imageWithData:data];
UIImageView *imgView = [[UIImageView alloc] initWithImage:img];
imgView.frame = CGRectMake(x, y, 106, 106);
[scrPhoto addSubview:imgView];
UIButton *btn= [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = imgView.frame;
btn.tag = counter;
[btn addTarget:self action:#selector(btnPhotoClicked:) forControlEvents:UIControlEventTouchUpInside];
[scrPhoto addSubview:btn];
if(counter %3 == 0 ){
y = y +106;
x = 0;
} else{
x =x + 106;
}
counter++;
}
[scrPhoto setContentSize:CGSizeMake(320, y)];
}
In my iPhone app I have a map view. In this I am displaying a number of pin views depends on the data from a web server. Here is the method I used for it.
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
NSString *identifier = #"myPin";
self.pinView = (MKPinAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (self.pinView == nil) {
self.pinView= [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier]autorelease]; //11.1%
} else {
self.pinView.annotation = annotation;
}
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; //20.4%
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
self.pinView.rightCalloutAccessoryView = rightButton; //2.7%
MyAnnotation *annot = (MyAnnotation*)annotation;
UIImageView *egoimageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"defaultPerson"]]; //17.5%
NSString *imageUrl = [NSString stringWithFormat:#"%#%#", CommonImageURL, [friendsProfileImageArray objectAtIndex:annot.tag]]; //9.4%
if ([[UIScreen mainScreen] respondsToSelector:#selector(displayLinkWithTarget:selector:)] &&
([UIScreen mainScreen].scale == 2.0)) {
// Retina display
[egoimageView setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage imageNamed:#"defaultPerson#2x.png"]]; //2.6%
egoimageView.image = [UIImage imageWithCGImage:egoimageView.image.CGImage scale:egoimageView.image.size.width/25 orientation:egoimageView.image.imageOrientation];
} else {
// non-Retina display
[egoimageView setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage imageNamed:#"defaultPerson.png"]]; //14.6%
egoimageView.image = [UIImage imageWithCGImage:egoimageView.image.CGImage scale:egoimageView.image.size.width/25 orientation:egoimageView.image.imageOrientation]; //1.6%
}
[egoimageView sizeToFit];
self.pinView.leftCalloutAccessoryView = egoimageView; //3.1%
[egoimageView release];
self.pinView.canShowCallout=YES;
self.pinView.animatesDrop=YES;
//pin color based on status.....
if ([annot.relationshipStatus intValue]==2 )
self.pinView.pinColor=MKPinAnnotationColorGreen;
else
self.pinView.pinColor=MKPinAnnotationColorPurple; //17.1%
return self.pinView;
}
In this I have mentioned the percentage of memory allocations. If I continuously load the map, the total memory usage increases and the app crashes. How can I properly fix this? I have tried to fix it, but I don't know what more I can do.
Please help, thanks in advance.
Almost sorted with my 1st app, just a simple news app but when I load it onto my iPhone the scroll seems jerky can someone have a look at my function and see if i'm doing something wrong.
I need the image on the right hand side thats why i'm using custom cells.
Thanks

You effectively say here, that as soon as the cell needs to be displayed, the image must be fetched and presented. This will cost some time - too much for a good user experience.
You should fetch the images before or while you present the table view, and cache them, e.g. in an array. Or you must handle things asynchronously, meaning that you do the loading in the background, and not wait with return cell; until the image is actually downloaded. This will be a little harder to get right.
Even if you asynchronously download images, you'll still have a jerky scroll.
Why? It's lazy image decompression. ios performs decompression at the moment it will be displayed on the screen. You have to manually decompress the images in a background thread.
Decompression does not merely mean instantiating a UIImage object. It can be somewhat complicated. The best solution, is to download SDWebImage and use the image decompressor that's included. SDWebImage will asynchronously download and perform decompression for you.
