目标C语言 添加时间延迟翻转动画在导航视图

Question

我有一个按钮'过滤器'在左侧的导航栏。在点击它，我想翻转动画与翻转延迟1.5秒，同时切换到下一个视图。如何添加代码呢?

我正在使用这个导航代码:

FilterViewController *vc = [[FilterViewController alloc] init];
vc.delegate = self;
[self.delegate pushViewController:vc  animated:UIViewAnimationTransitionFlipFromLeft];
[vc release];

现在我想要一个1.5秒的翻转延迟在视图切换按钮。我已经尝试了一些代码，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];

取自如何在点击信息按钮时在两个uiviewcontroller之间翻转动画?

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];
                         }];

我从如何在基于导航的应用程序中更改Push和Pop动画

Answer 2

使用这个来延迟推送动画:

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];
}
