淡入查看 [英] fade View IN and OUT

问题描述

大家早上好

我对这个问题完全感到困惑。

I'm totally confused with this problem.

我有3个UIWebViews而应该发生的是webView1淡入（起作用）淡出和WebView2淡入......

I have 3 UIWebViews and what should hapen is webView1 fades in (that works) fades out und WebView2 fades in......

到目前为止，我做到了：

I made it so far with:

CATransition *Animation = [CATransition animation];
[Animation setDuration:4.0];
[Animation setType:kCATransitionFade];
[Animation setSubtype:kCATransitionFade];
[Animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];


transitioning = YES;

if (transitioning) {
    [self.webView1.layer addAnimation:Animation forKey:nil];
    self.webView1.hidden = YES;
    self.webView2.hidden = NO;

有人可以帮我吗？

当它在webView中消失时，即使背景颜色设置为其他颜色，它也会从白色逐渐消失！
我不能影响颜色吗？

And when it fades in the webView fades from white even the background color is set to an other color! can't I effect the color?

推荐答案

您应该使用 UIView 隐式动画。例如，从webView1到webView2的交叉淡入淡出：

You should use UIView implicit animations. For instance, a cross fade from webView1 to webView2:

[UIView beginAnimations:@"fade" context:nil];
self.webView1.alpha = 0.0;
self.webView2.alpha = 1.0;
[UIView commitAnimations];

如果要在动画结束后执行一些代码，请将其插入begin和commit之间：

If you wanna execute some code after the animation finished, insert this between begin and commit:

[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(fadeAnimationDidStop:finished:context:)];

并创建带有签名的didStop方法

and create the didStop method with the signature

- (void)fadeAnimationDidStop:(NSString*)animationID finished:(NSNumber*)finished context:(void*)context`
