Question

点击按钮，我在当前视图上放置了透明视图。对于覆盖整个屏幕（包括导航栏）的透明视图，我编码如下：

[AppDelegate.window.rootViewController.view addSubview:coverView];

在按钮点击操作中，我放了一些动画代码。

现在，在透明视图中单击按钮，我已经使用以下代码执行滑动过渡效果：

    CATransition *animation = [CATransition animation];
    [animation setDuration:0.8];
    [animation setType:kCATransitionPush];
    [animation setSubtype:kCATransitionFromLeft];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
    [[TransparentView.view layer] addAnimation:animation forKey:nil];
    [TransparentView removefromSuperview];

我需要透明视图向左/右滑动（换句话说......从视图中移除TransparentView），MainView应该像以前一样显示。

但它不起作用.. 有人可以帮忙吗？

Answer 1

arturdev部分正确!!他现在在做的是 - - ＆GT;从左到右添加CATransition动画0.8秒，之后视图仍然存在。 - ＆GT;然后从superview中删除它。

而不是那样，通过改变它的框架来隐藏transparentView（这里我用框架宽度替换它的x坐标）。然后添加转换。

[coverView setFrame:CGRectMake([coverView frame].size.width, 0, coverView.frame.size.width, coverView.frame.size.height)];
[CATransaction begin];
CATransition *animation = [CATransition animation];
[CATransaction setCompletionBlock:^{
    [coverView removeFromSuperview];
}];
[animation setDuration:0.8];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[coverView layer] addAnimation:animation forKey:nil];
[CATransaction commit];

Answer 2

[CATransaction begin];
CATransition *animation = [CATransition animation];
[CATransaction setCompletionBlock:^{
    [TransparentView removefromSuperview];
}];
[animation setDuration:0.8];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[TransparentView.view layer] addAnimation:animation forKey:nil];
[CATransaction commit];

完成动画 - 过渡后删除子视图
