App stalls - no crash, no error

It is worth noting that this part of the app (this option from the main menu) was working perfectly before. I then programmed the next option from the main menu, and now this one is not working anymore.

I know开发者_JS百科 the code I've written works, but there is something wrong with either the class or the xib, because it worked when I switched it to call a different class/xib from:

UIViewController *nextController = [[OneMethodController alloc] initWithNibName:@"OneMethodController" bundle:nil];

to:

UIViewController *nextController = [[SecondMethodController alloc] initWithNibName:@"SecondMethodController" bundle:nil];

When I try to load the first class/xib (which used to work, as I said), the app just stalls indefinitely. There is no error and the app does not crash.

Any ideas? THANKS!!

Note that *nextController should most likely be initialized as

SecondMethodController *nextController = [[SecondMethodController alloc] init . . .

And not as

UIViewController *nextController = [[SecondMethodController alloc] init . . .

The issue was not with the XIB but with the viewDidLoad of that XIB's class. Thanks @cool_me5000 for your help with this.
