淡出 MPMoviePlayerController 控件 [英] Fading out MPMoviePlayerController controls

问题描述

当我在 MPMoviePlayerController 中开始播放电影时，控件会在顶部停留几秒钟.之后，它们逐渐淡出.

When I start a movie in a MPMoviePlayerController, controls stay at the top for few seconds. After that, they fade out.

当我在 controlStyle 属性中使用 MPMovieControlStyleNone 时，我想模拟这种效果，但控件突然消失了.我尝试使用以下代码使用动画但没有成功:

I want simulate this effect when I use MPMovieControlStyleNone in controlStyle property, but controls disappear abruptly. I tried to use animations without success with the following code:

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.50f];
        self.myMoviePlayer.controlStyle = MPMovieControlStyleNone;
        [UIView commitAnimations];

有人知道我怎么做吗?

任何帮助将不胜感激.

谢谢.

推荐答案

如果我理解正确，您打算以与原始控件类似的方式隐藏自定义控件.

If I understand you correctly, you are planning to hide custom controls in a similar fashion to the original controls.

您将需要使用类似

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.50];
self.customControlsView.alpha = 0.0f;
[UIView commitAnimations];

达到那个效果.controlStyle 不是可动画的属性.

to achieve that effect. controlStyle is not an animatable property.

最重要的是，您需要在 MPMoviePlayerController 的整个生命周期中始终坚持 controlStyle = MPMovieControlStyleNone，因为这是防止原始控件出现的唯一方法.

On tops, you will need to stick to controlStyle = MPMovieControlStyleNone anyways throughout the lifetime of your MPMoviePlayerController as that is the only way to prevent the original controls from appearing.
