在导航视图上添加时间延迟以翻转动画

Question

我在导航栏的左侧有一个“过滤器”按钮。点击它我想要翻转动画，翻转延迟1.5秒，同时切换到下一个视图。如何添加代码？

我正在使用此导航代码：

FilterViewController *vc = [[FilterViewController alloc] init];
vc.delegate = self;

[self.delegate pushViewController:vc  animated:UIViewAnimationTransitionFlipFromLeft];

[vc release];

现在我希望按钮上的视图切换时间为1.5秒。我尝试了一些代码，但它没有给我想要的结果。

Answer 1

试试这个

    [UIView beginAnimations:@"View Flip" context:nil];
    [UIView setAnimationDuration:1.5];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight 
                           forView:self.navigationController.view cache:NO];

    [self.navigationController pushViewController:vc animated:YES];
    [UIView commitAnimations];

    [vc release];

取自How to do the flip animation between two UIViewControllers while clicking info button?

其他方式：

MainView *nextView = [[MainView alloc] init];
[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [super pushViewController:nextView animated:NO];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                         }];

使用它来延迟推送动画：

FilterViewController *vc = [[FilterViewController alloc] init];
vc.delegate = self;
[self performSelector:@selector(callViewController:) withObject:vc afterDelay:1.5];

-(void)callViewController:(FilterViewController*)vc{
    [self.delegate pushViewController:vc  animated:UIViewAnimationTransitionFlipFromLeft];
    [vc release];
}
