I hope this helps . Simply alloc,init will give you blank controller with no view associated with it. You have to initialise it through storyboard like this, then you will not have to provide any custom init/alloc,
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; ChooseLeagueCollectionViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"yourViewControllerIdentifier"]; [self presentViewController:vc animated:NO completion:NULL];

will help you I am struck with a new problem, on presenting the destinationViewController using custom segue, during transition the source ViewController is changed to black screen, i need the screen to be as it is (my design). , I think you need to keep the context, try this:
code :
    UIViewController *rootViewController = [UIApplication sharedApplication].delegate.window.rootViewController;
    rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
    UIViewController *destinationController = (UIViewController*)[self destinationViewController]
    [sourceViewController presentViewController:destinationController animated:NO completion:nil];

seems to work fine The cell is probably not responding to touches because you haven't set the image view's userInteractionEnabled property to YES (it's NO by default).
You can't use an unwind segue to go forward; they're for going back to a previous controller, so your preference to use an unwind segue doesn't make sense. Do you mean for the unwind segue to be used for going back from the detail VC? It's not clear where you want this custom button. You already have the segue connected from the cell, so you don't need a button to invoke the segue.

I hope this helps you . OK. Here's what happened. I'm on a slow Mac with 4 GB of RAM. What caused the error was two view outlets on the tableView. One to the parent view and one to the tableView itself. The reason this happened was that the Mac is slow when dragging out lines to wire up the storyboards and I didn't see if one of the attempts to wire up the view outlet hit the tableView and connected, so I did it again. It actually did wire up the view outlet, but to the parent view. This resulted in two view outlets for the tableView. What is odd is that intermittently, one was chosen over the other. It wasn't deterministic. Thinking about this, this information may be stored in an internal dictionary which is inherently unordered.
So, when I duplicated that scene, I now had two scenes with the same multiple view connection issue. If it didn't happen on one, it might happen on the other.
