同一个 UIViewController 中的 UIView 之间的转换

Question

当我按下按钮时，我想在 UIViewController 中从 UIView 转换到另一个

我写了这段代码：

- (IBAction)changeView:(id)sender {

    CATransition* transition = [CATransition animation];
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    transition.duration = 1.0f;
    transition.type =  @"cube";
    transition.subtype = @"fromTop";
    [self.view1.layer removeAllAnimations];
    [self.view1.layer addAnimation:transition forKey:kCATransition];


}

此代码会将 view1(UIview) 传输到它自己。我怎样才能让它过渡到另一个 UIView（例如 view2）。我还可以在情节提要中将另一个 UIview (view2) 放在哪里

Answer 1

如果您有两个 UIView，例如将 firstView 和 secondView 添加到同一矩形上的 UIViewController。并将隐藏属性设置为 secondView。

-(IBAction)flipFirstViewToSecondView{
secondView.hidden= NO;
    [UIView transitionWithView:firstView duration:1.0f options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{

        [UIView transitionWithView:secondView duration:1.0f options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{

        } completion:^(BOOL finished) {
            secondView.hidden = NO;
            firstView.hidden = YES;
        }];

    } completion:^(BOOL finished) {

    }];
}

谢谢。如果您在集成它时遇到任何问题，请告诉我。

看看这段代码 sn-p 它更优雅。还可以查看 Apple 的文档以了解更多花哨的 UIViewAnimationOptions

- (IBAction)changeView:(id)sender
{
    [UIView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{
        //Remove View-1 from the main view
        [view1 removeFromSuperView];
        //Add the new view to your current view
        [self.view addSubView:view2];
    } completion:^(BOOL finished) {
        //Once animation is complete
    }];
}

确保这两个视图是视图控制器的强属性。

你试过这样吗？

  self.view1.alpha = 0.0;

 [UIView beginAnimations:@"flip" context:nil];

 [UIView setAnimationDelegate:self];

 [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];

 [UIView setAnimationDuration:1.0f];

  self.view2.alpha = 1.0;   

  [UIView commitAnimations];
