在iOS6中进入全屏后，MPMoviePlayerController会中断/停止 [英] MPMoviePlayerController breaks/stops after going to fullscreen in iOS6

问题描述

我有一个 MPMoviewPlayerViewController 嵌入到 UIView 对象中。当我在嵌入模式下启动播放器时，一切正常并且符合预期。如果用户然后点击全屏切换（或者如果我使用 setFullscreen：animated 以编程方式更改为全屏），则播放器全屏显示，电影播放另一秒钟，之后屏幕变黑，只有正在加载... 消息。

此行为仅在使用iOS 6（也是iPad 6.0模拟器）时出现，在运行iOS 5的设备上，一切都按预期工作。

电影源是应用程序包中的本地文件。

在比赛中进入全屏调试输出如下：

有人知道为什么玩家会停止工作吗？

添加了 github上的示例项目

解决方案

我自己解决了。当我将Movie Player作为子视图添加到容器视图时，我不需要使用用 MPMoviePlayerViewController 创建的实际视图控制器，该控制器旨在用于呈现它modally或其他vc层次结构。

为了让电影播放器​​视图可以作为子视图添加到其他视图的单一目的 MPMoviePlayerController 的视图属性已足够。

直到iOS 6都有效，但iOS 6在资源管理/生命周期方面似乎有所不同。

示例项目使用工作代码进行更新。

I have a MPMoviewPlayerViewController embedded into an UIView object. When I start the player in the embedded mode everything works fine and as expected. If the user then taps onto the fullscreen toggle (or if I change to fullscreen programmatically using setFullscreen:animated) the player goes fullscreen, the movie plays for another second and after that the screen goes black with only a "Loading..." message.

This behavior only appears using iOS 6 (also iPad 6.0 Simulator), on devices running iOS 5 everything works as intended.

The movie source is a local file from the app bundle.

Upon playing & entering fullscreen the debug output is as follows:

Has somebody an idea why the player stops working?

Edit: Added an example project on github

解决方案

I solved it by myself. As I add the Movie Player as a subview to a container view I don't need to use the actual view controller created with the MPMoviePlayerViewController which is intended to be used to present it modally or in some other vc hierarchy.

For the single purpose of having a Movie Player view that can be added to some other view as a subview the MPMoviePlayerController's view property is sufficient.

Until iOS 6 both worked but iOS 6 seems to differ in terms of ressource management/lifetime.

The example project is updated with working code.
