UIMoviePlayerControllerDidEnterFullscreenNotification在iOS8中不起作用 [英] UIMoviePlayerControllerDidEnterFullscreenNotification doesn't work in iOS8

问题描述

我正在使用 UIWebView 使用iFrame播放YouTube视频。

我正在使用 UIMoviePlayerControllerDidEnterFullscreenNotification 将youtube屏幕检测到全屏。

如下代码：

I am using UIWebView to play a youtube video with iFrame.
I am using UIMoviePlayerControllerDidEnterFullscreenNotification to detect youtube screen into fullscreen.
Like below code :

[[NSNotificationCenter defaultCenter] addObserver: self
                                         selector: @selector(myMovieEnterFullScreen:)
                                             name: @"UIMoviePlayerControllerDidEnterFullscreenNotification"
                                           object: nil];

它适用于iOS7。

但我尝试在iOS8中运行它。

它不起作用。

我认为通知名称已被更改。

有没有办法在ios8中检测youtube全屏事件？

It works in iOS7.
But I try to run it in iOS8.
It doesn't work.
I think the notification name has be changed.
Has any alternative to detect the youtube fullscreen event in ios8?

推荐答案

markussvensson的实现有一些误报，因为任何UIWindowDidBecomeVisibleNotification都被视为全屏视频播放，但这不是真的。

The implementation by markussvensson has some false alarms, since any UIWindowDidBecomeVisibleNotification is considered as a full screen video playback which is not true.

Selvin的实现AVPlayerItemBecameCurrentNotification可以捕捉电影播放开始，但无法捕捉电影播放停止。

The implementation "AVPlayerItemBecameCurrentNotification" by Selvin can catch movie playback start, but cannot catch movie playback stop.

所以我结合两种实现，它按预期工作。

So I combined both implementations and it works as expected.

1. 将观察者添加到AVPlayerItemBecameCurrentNotification& UIWindowDidBecomeHiddenNotification;

1. Add observer to both AVPlayerItemBecameCurrentNotification & UIWindowDidBecomeHiddenNotification;

当AVPlayerItemBecameCurrentNotification发生时，设置一个标志;

When AVPlayerItemBecameCurrentNotification happens, set a flag;

当UIWindowDidBecomeHiddenNotification发生时，检查标志是否是视频停止播放事件。

When UIWindowDidBecomeHiddenNotification happens, check the flag to see if it is a "video stop playing event".

BTW，AVPlayerItemBecameCurrentNotification未记录，可能为下一个iOS主要版本打破。

BTW, AVPlayerItemBecameCurrentNotification is undocumented and might be broken for the next iOS major release.
