In my project, I always use SLComposeViewController to share contents with third-party apps, but now, when I update my iPhone to iOS 11 beta, this no longer works.
The SLComposeViewControllerCompletionHandler always callback SLComposeViewControllerResultCancelled.
Why is this?
I was having problems with regard to the SLComposer in iOS 11. But I just removed the line that checks and apparently the own SDK makes the validacoes to me internally.
Remove this line serves for any SLServiceType:
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
So, develop your logic. In my case:
SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[mySLComposerSheet setInitialText:@"#myInitialTextIsHere"];
[mySLComposerSheet addURL:[NSURL URLWithString:strURL]];
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
switch (result) {
case SLComposeViewControllerResultCancelled:
NSLog(@"Post Canceled");
break;
case SLComposeViewControllerResultDone:
NSLog(@"Post Sucessful");
break;
default:
break;
}
}];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
I hope I have helped!
For iOS 11 this line:
([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
is always returning NO
I replaced it with check if user has Facebook app installed with:
static NSString *const canOpenFacebookURL = @"fbauth2";
+ adding it to LSApplicationQueriesSchemes in plist
-(BOOL)isFacebookAppInstalled {
NSURLComponents *components = [[NSURLComponents alloc] init];
components.scheme = canOpenFacebookURL;
components.path = @"/";
return [[UIApplication sharedApplication]
canOpenURL:components.URL];
}
And then just call SLComposeViewController *composeVC = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
as usual, the same how Matheus Domingos described. But with this check at least you know that user has facebook app installed.
