iOS 8.3 and later, Facebook share text not inserted

问题

After updating to iOS 8.3 the text is not inserted into the share dialog

i use a standard

UIActivityViewController *vc = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:applicationActivities];
NSArray *excludeActivities = @[UIActivityTypeAssignToContact];
vc.excludedActivityTypes = excludeActivities;

if (IsUserInterfaceIdiomPad) {
    vc.popoverPresentationController.sourceView = self.navigationController.view;
}
[self.navigationController presentViewController:vc animated:YES completion:^{

}];

where the items are a NSString and an NSURL

回答1:

Looks like Facebook doesn't want the app to pre-propagate the share dialog with text anymore :(

It doesn't have to do anything with the iOS version, but with the build in Facebook App (as the share processes is somehow interlinked with the FB app)

It's stupid and on Android you couldn't do it either (it was disabled longer ago) i hope Facebook reconsiders this as it will lead to fewer shares and some might be willing to drop the share option

Note: if the user doesn't have the FB app installed (he removed it), than the text is added to the status, but i guess that only a small amount of users, but maybe a good reason to still supply text to the share items

   NSString *strName= @"Mohit Thatai";
   FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
   [login
    logInWithReadPermissions: @[@"public_profile", @"email"]
    handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
       if (error)
       {
          NSLog(@"Process error");
       }
       else if (result.isCancelled)
       {
          NSLog(@"Cancelled");
       }
       else
       {
         FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
          [content setContentTitle:@"GPS Tracker"];
          [content setContentDescription:[NSString stringWithFormat:@"%@ shared an interesting link\n       This might be interesting to you: GPS Tracker for Kids",strName]];
 content.contentURL = [NSURL URLWithString:[NSString stringWithFormat:@"http://gpsphonetrackerkids.com"]];
          [FBSDKShareDialog showFromViewController:self
                                       withContent:content
                                          delegate:nil];
       }
    }];
