1. 如果楼主想要使用UINavigationController中的view controller stack，并且还想要同时自定义push、pop的动画效果，基本上是不可能的。原因在于想要使用view controller stack，就无法躲开pushViewController:animated:这个方法，而一旦使用pushViewController:animated:，UINavigationController就会强制将要推入的viewController的frame设为当前可视区域的frame，从而断绝一切想要自定义动画的后路，例如如下代码，是不会产生任何效果的：UINavigationController+CustomAnimation.h@interface UINavigationController (CustomAnimation)- (void)customPushViewController:(UIViewController *)viewController;@endUINavigationController+CustomAnimation.m#import "UINavigationController+CustomAnimation.h"- (void)customPushViewController:(UIViewController *)viewController
{
viewController.view.frame = (CGRect){0, -viewController.view.frame.size.height, viewController.view.frame.size};
[self pushViewController:viewController animated:NO];
[UIView animateWithDuration:.15f
animations:^{
viewController.view.frame = (CGRect){0, 0, self.view.bounds.size};
}];
}2. 如果仅仅是想添加自定义的push、pop动画，而不使用view controller stack，那么，如下代码就可以实现一个从上到下的push效果：UINavigationController+CustomAnimation.h文件同上。UINavigationController+CustomAnimation.m#import "UINavigationController+CustomAnimation.h"- (void)customPushViewController:(UIViewController *)viewController
{
viewController.view.frame = (CGRect){0, -viewController.view.frame.size.height, viewController.view.frame.size};
[self.topViewController.view addSubview:viewController.view];
[UIView animateWithDuration:.15f
animations:^{
viewController.view.frame = (CGRect){0, 0, self.view.bounds.size};
}];
}
