iphone - 单击导航栏中的 "Back"按钮时阻止动画？

Question

我的应用程序有一个导航 Controller ，但我不希望其中有任何动画:

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

• 但是当我单击此 subview 上的“后退”按钮时，会出现动画! KO!我该怎么做才能阻止这个动画？

Answer 1

这会阻止默认动画。

- (void)viewWillDisappear:(BOOL)animated {
    [UIView setAnimationsEnabled: NO];
}

- (void)viewDidDisappear:(BOOL)animated {
    [UIView setAnimationsEnabled: YES];
}

如果您需要自定义动画

- (void)viewWillDisappear:(BOOL)animated {
    [UIView setAnimationsEnabled: NO];

    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.type = kCATransitionFade;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
}

- (void)viewDidDisappear:(BOOL)animated {
    [UIView setAnimationsEnabled: YES];
}
