- （无效）viewWillAppear中：（BOOL）动画检测自定义动画 [英] - (void)viewWillAppear:(BOOL)animated detect custom animation

问题描述

我有一个按钮，当pressed推视图控制器但是我使用自定义动画等等 pushViewController：childController动画：设置为NO。我想要做虽然在我的检测到这种自定义动画 - （无效）viewWillAppear中：（BOOL）动画方法，如果这样的语句写;

I have a button which when pressed pushes a view controller however i'm using a custom animation so pushViewController: childController animated: is set to NO. What i want to do though is detect this custom animation in my - (void)viewWillAppear:(BOOL)animatedmethod and write an if statement like this;

- (void)viewWillAppear:(BOOL)animated { 
     if (customAnimation occured) {//Do this} 
     else {//Do this}
}

这是推视图控制器为我的按钮的方式。

This is the method for my button which pushes the view controller.

- (void)nextPressed:(id)sender {
    childController = [[CategoryOneDetailController alloc] initWithNibName:xibDownName bundle:nil];
    [UIView  beginAnimations: @"Showinfo"context: nil];
    [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.75];
    [self.navigationController pushViewController: childController animated:NO];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.navigationController.view cache:NO];
    [UIView commitAnimations];
    [childController release];
}

任何帮助将是非常美联社preciated，谢谢，萨米。

推荐答案

如果你不使用标准的动画，我觉得最好的办法就是添加属性被设置为是在自定义动画（和 NO 默认情况下不会破坏任何现有的行为）的情况下。然后，你可以检查属性 viewDidAppear：

If you don't use standard animations, I think your best bet is to add a property to your pushed view controller that is set to YES in case of a custom animation (and NO by default to not break any existing behavior). Then you can check that property in viewDidAppear:.

如果您需要自定义逻辑被执行的之后的动画已经用完，你可能想建立一个动画完成处理程序或块。

If you need your custom logic to be executed after the animation has run, you might want to set up an animation completion handler or block.
