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);

Answer 2

获取父视图控制器的类：

id class = [self.navigationController.viewControllers[0] class];

及其名称：

NSString *className = NSStringFromClass(class);
