count view controllers

Question

I can't seem to get the number of view controllers in the view controller stack.

NSUInteger *viewControllerCount = self.navigationController.viewControllers.count;

I can loop through the view controllers and NSLog the objects within but I can't do a simple count. If I try to access this pointer, the ap crashes... no Log, no error message, nada. Please help!

Answer 1

I believe you want to remove the *:

NSUInteger viewControllerCount = self.navigationController.viewControllers.count;

Answer 2

The reason why this isn't working is because NSUInteger isn't an object type, it's a language type.

Therefore, you need to remove the * from the assignment and it should work just fine.
