【问题标题】:how make view transition like iPad appstore on iOS 7如何在 iOS 7 上像 iPad appstore 一样进行视图转换
【发布时间】:2014-05-29 01:02:27
【问题描述】:

我想进行视图转换,例如 iOS 7 上的 iPad AppStore,单击一个项目(应用程序)并弹出一个带有垂直翻转的详细视图,然后在详细视图之外点击将关闭,此视图转换既不像 popover 和模态过渡。 那么,我该如何进行这种过渡...

感谢您的帮助。

    【解决方案1】:

    也在寻找过渡动画。但我确实想出了如何在窗口外完成点击以关闭/关闭。可以找到here

    在您的viewDidAppear 中,您创建一个 UITapGestureRecognizer 并将其添加到视图的窗口中。像这样:

    UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)];
    [recognizer setNumberOfTapsRequired:1];
    recognizer.cancelsTouchesInView = NO;
    [self.view.window addGestureRecognizer:recognizer];
    

    handleTapBehind 检查手势状态是否已结束并获取点击的位置并关闭视图/窗口

    - (void)handleTapBehind:(UITapGestureRecognizer *)sender{
        if (sender.state == UIGestureRecognizerStateEnded){
            CGPoint location = [sender locationInView:nil]; //Passing nil gives us coordinates in the window
    
            //Check to see if it's in or outside. If outside, dismiss the view.
            if (![self.view pointInside:[self.view convertPoint:location fromView:self.view.window] withEvent:nil]){
                // Remove the recognizer first so it's view.window is valid.
                [self.view.window removeGestureRecognizer:sender];
                [self dismissViewControllerAnimated:YES completion:nil];
            }
        }
    }
    

    希望这会有所帮助!

      【解决方案2】:

      开始here。这是一个例子:

      [UIView transitionWithView:newView
                        duration:1
                         options:UIViewAnimationOptionTransitionFlipFromLeft 
                      animations:^{         // put the animation block here
                                 }
                      completion:NULL];
