There's a built-in way to dump the view hierarchy: recursiveDescription

NSLog(@"%@", [view recursiveDescription]);

It will output something like this:

<UIView: 0x6a107c0; frame = (0 20; 320 460); autoresize = W+H; layer = […]
   | <UIRoundedRectButton: 0x6a103e0; frame = (124 196; 72 37); opaque = NO; […]
   |    | <UIButtonLabel: 0x6a117b0; frame = (19 8; 34 21); text = 'Test'; […]
