我推着这样的观点。
[[self.navigationController pushViewController:myViewController animated:YES];
我怎样才能从推视图（子视图）的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);
Answer 2:
获取类父视图控制器：
id class = [self.navigationController.viewControllers[0] class];
和它的名字：
NSString *className = NSStringFromClass(class);
