只是Facebook上的sharing....can，你能告诉我我哪里出错了吗？

Question

facebook文本共享中的问题，如果共享twitter或任何社交媒体，那么问题就发生了。在我犯错误的地方，请告诉我：

NSString *textToShare = [NSString stringWithFormat:@" Hi stackoverflow;

NSArray *objectsToShare = @[textToShare];

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                                             UIActivityTypePrint,
                                   UIActivityTypeAssignToContact,
                                  UIActivityTypeSaveToCameraRoll,
                                  UIActivityTypeAddToReadingList,                                
                                      UIActivityTypePostToFlickr,    
                                       UIActivityTypePostToVimeo];     
           activityVC.excludedActivityTypes = excludeActivities;

 [self presentViewController:activityVC animated:YES completion:nil];
