单击“返回"时阻止动画；导航栏中的按钮? [英] Prevent the animation when clicking "Back" button in a navigation bar?

问题描述

我的应用程序有一个导航控制器，我不希望它有任何动画:

My application has a navigation controller and I don't want any animation in it :

• 要在推送视图时阻止动画，很简单，通过 pushViewController:animated: 方法

• to prevent an animation when pushing a view, it's easy, via the pushViewController:animated: method

但是当我点击这个子视图上的返回"按钮时，有一个动画！KO！我可以做些什么来阻止这个动画?

but when I click the "back" button on this subview, there's an animation ! KO ! What can I do to prevent this animation ?

推荐答案

更优雅的一个类别.这假设您在应用程序委托中设置了导航控制器对象.只需将其放在根视图控制器中的 @implementaion 之前即可.

More elegant with a category. This assumes you navigation controller object is set in your app delegate. Just put this before your @implementaion in the root view controller.

#import "AppDelegate.h"

@implementation UINavigationBar (custom)
- (UINavigationItem *)popNavigationItemAnimated:(BOOL)animated;
{

    AppDelegate *delegate = [[UIApplication sharedApplication] delegate];

    [delegate.navController popViewControllerAnimated:NO];

    return TRUE;
}
