Warning: Attempt to present ModalTableViewController on MainTableViewController which is already presenting (null)
I had this issue because I was trying to perform segue / present from within:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndexI changed it to:
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndexand it fixed it!
I'm not on swift yet, but for Objective-C, I ended up wrapping the presentViewController call in a performSelector call.
-(void) present{ [self performSelector: @selector(ShowModalTableViewController) withObject: nil afterDelay: 0];}-(void) ShowModalTableViewController{ [self presentViewController: ctrlModalTableViewController animated: true completion: nil];}
This will work also:
dispatch_async(dispatch_get_main_queue(), ^ { [self presentViewController:vc animated:YES completion:nil];});
