在iPhone Navigation push中获取Parent View控制器的类名

Question

我正在推这样的观点.

[[self.navigationController pushViewController:myViewController animated:YES];

如何从推送视图(子视图)获取父视图控制器的类名？ Any Idea?

Answer 1

这应该这样做:

NSUInteger numberOfViewControllersOnStack = [self.navigationController.viewControllers count];
UIViewController *parentViewController = self.navigationController.viewControllers[numberOfViewControllersOnStack - 2];
Class parentVCClass = [parentViewController class];
NSString *className = NSStringFromClass(parentVCClass);
