What is the best way to implement SFSafariViewController using Objective-C. I currently have a UITableView and each of them leads to a different website. May I know how can I code each of them to load a different website in SFSafariViewController using Objective-C, not Swift? Thanks in advance!
This will work with newer versions like 10.
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:#"http://google.com"]];
if ([SFSafariViewController class] != nil) {
SFSafariViewController *sfvc = [[SFSafariViewController alloc] initWithURL:URL];
[self presentViewController:sfvc animated:YES completion:nil];
} else {
[[UIApplication sharedApplication] openURL:URL];
}
Here's a version that checks the iOS version to handle iOS 8, and open links in safari if SFSafariViewController isn't compatible
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:#"http://google.com"]];
if ([[UIDevice currentDevice].systemVersion hasPrefix:#"9"]) {
SFSafariViewController *sfvc = [[SFSafariViewController alloc] initWithURL:URL];
[self presentViewController:sfvc animated:YES completion:nil];
} else {
[[UIApplication sharedApplication] openURL:URL];
}
Then also call this to handle the done button
- (void)safariViewControllerDidFinish:(nonnull SFSafariViewController *)controller {
[controller dismissViewControllerAnimated:YES completion:nil];}

When I want to open App2 in App1, I can do like this:
NSURL * myURL_APP_A = [NSURL URLWithString:#"openurl1://"];
if ([[UIApplication sharedApplication] canOpenURL:myURL_APP_A]) {
[[UIApplication sharedApplication] openURL:myURL_APP_A];
}
But when I want to open an App in a keyboard Extension, [UIApplication sharedApplication] cannot be used.So how can I make it?
Thanks for your help!
You can try this method :
NSURL *url = [NSURL URLWithString:#"myapp://"];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectZero];
[self.view addSubview:webView];
[webView loadRequest:urlRequest];
[UIApplication sharedApplication] openURL is currently not allowed in custom keyboards. You should see an error message popping up that tells you exactly that.
I have tried to post on facebook and twitter using SLComposeViewController. my code is
-(void)postToFacebookWithObject:(id)object FromController:(UIViewController*)vc {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
if (result == SLComposeViewControllerResultCancelled)
{
DLog(#"Cancelled");
}
else
{
DLog(#"Done");
}
[controller dismissViewControllerAnimated:YES completion:Nil];
};
controller.completionHandler =myBlock;
[controller removeAllImages];
[controller removeAllURLs];
NSMutableDictionary *item = (NSMutableDictionary *)object;
[controller setInitialText:[item objectForKey:#"DealTitle"]];
if([item objectForKey:#"DealImage"])
[controller addImage:[item objectForKey:#"DealImage"]];
if([item objectForKey:#"url"])
[controller addURL:[NSURL URLWithString:[item objectForKey:#"url"]]];
[vc presentViewController:controller animated:YES completion:Nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"" message:LocStr(#"NO_FACEBOOK_ACCOUNT_CONFIGURED") delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
DLog(#"UnAvailable");
}
}
this working fine in ios 7 but in ios 8 this sheet coming behind my view which i have added on window. How i can fix this?
I have solve this issue by adding my view on navigationcontroller.view not on window.
I have resolved through open present-view controller in navigation-bar.it may help you.
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[controller setInitialText:shareFrom];
[controller addImage:self.photoImageView.image];
[controller addURL:[NSURL URLWithString:dayCareWebsite]];
dispatch_async(dispatch_get_main_queue(), ^ {
[self.navigationController presentViewController:controller animated:YES completion:nil];
});
UINavigationController *forShare = [[UINavigationController alloc] initWithRootViewController:vc];
[forShare setNavigationBarHidden:YES];
[self presentViewController:forShare animated:NO completion:nil];
if animated:YES it doesn't works
if animated:NO it works for me
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSMutableDictionary* meta = [[NSMutableDictionary alloc] initWithDictionary:[info objectForKey:UIImagePickerControllerMediaMetadata]];
UIImage* img = [info objectForKey:UIImagePickerControllerOriginalImage];
if(self.locationManager.location){
NSDictionary* locationMeta = [self gpsDictionaryForLocation:self.locationManager.location];
[meta setObject:locationMeta forKey:(NSString*)kCGImagePropertyGPSDictionary];
}
ALAssetsLibrary* library = [[ALAssetsLibrary alloc] init];
[library writeImageToSavedPhotosAlbum:img.CGImage metadata:meta completionBlock:^(NSURL* assetUrl, NSError* error){
//.......
}
[picker dismissViewControllerAnimated:YES completion:nil];
}
This code worked fine in iOS7. After I upgraded my device to iOS8, the program was blocked and imagePickerView didn't dismiss.
Is this a bug in iOS8? Anyone can help me?
After picking image from UIImagePickerController I want to Tweet it but there is error!
Warning: Attempt to present <SLTwitterComposeViewController: 0x210d84b0> on <UITabBarController: 0x1fd67650> while a presentation is in progress!
P.S
This is tabbar application (4 tabbars)
All code:
-(void)useCamera:(id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
UIImagePickerController *imagePicker =[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = #[(NSString *) kUTTypeImage];
imagePicker.allowsEditing = NO;
[self presentViewController:imagePicker animated:YES completion:nil];
_newMedia = YES;
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
NSString *mediaType = info[UIImagePickerControllerMediaType];
[self dismissViewControllerAnimated:YES completion:nil];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
[self buttonTweet:info[UIImagePickerControllerOriginalImage]];
}
}
- (IBAction)buttonTweet:(id)sender {
SLComposeViewController *composeController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[composeController setInitialText:[NSString stringWithFormat:#"#this is tweet text"]];
[composeController addImage:sender];
[composeController addURL: [NSURL URLWithString:#"http://www.abc.com"]];
[self presentViewController:composeController animated:YES completion:nil];
}
You are presenting a new view controller while the old one is still disappearing. You can present the new one upon completion of the other animation by doing it like this:
[self dismissViewControllerAnimated:YES completion:^{
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
[self buttonTweet:info[UIImagePickerControllerOriginalImage]];
}
}];
I have a problem with the UIActivityViewController on iPad
Here is my Code:
NSString* someText = #"Hi, I am using the official iEveryThing Tech app #iEveryTech";
NSString* Website = [NSURL URLWithString:#"https://itunes.apple.com/us/app/ieverytech/id578148847?l=de&ls=1&mt=8"];
NSArray* dataToShare = #[someText,Website];
Class activityViewController = NSClassFromString(#"UIActivityViewController");
if(activityViewController) {
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];}
}
On iPhone the Mail composer View will disappear after sending the mail but not the Composer on the iPad here is my Composer:
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
if (error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"error"
message:[NSString stringWithFormat:#"error %#", [error description]]
delegate:nil cancelButtonTitle:#"Dismiss" otherButtonTitles:nil, nil];
[alert show];
[self dismissModalViewControllerAnimated:YES];
}
else {
[self dismissModalViewControllerAnimated:YES];
}
}
The activityViewController use a native method for send mail don't need use mailComposeController, like this
NSMutableArray *items = [NSMutableArray new];
[items addObject:#"text for share"];
[items addObject:[UIImage imageWithData:[NSData dataWithContentsOfFile:self.imagePath]]];
NSArray *activityItems = [NSArray arrayWithArray:items];
self.activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:[NSArray arrayWithObjects:whatsapp,instagram, nil]];
self.activityVC.excludedActivityTypes = #[UIActivityTypeAssignToContact, UIActivityTypePrint,UIActivityTypeAirDrop,UIActivityTypeCopyToPasteboard];
[self presentViewController:self.activityVC animated:YES completion:nil];
First thing, when using the activityViewController, your class is not the delegate for the mail composer and the code will not be called. This is all handled internally in the activityViewController.
As for your view not being dismissed, implement the complete block call for the activityViewController. In the block be sure to dismiss the view controller.
