嵌入式UIWebView YouTube音量 [英] Embedded UIWebView YouTube Volume

问题描述

我正在使用可在UIWebView中显示YouTube影片的iOS应用程式。一切都很好，除非...

I'm working on an iOS app that can display YouTube videos in a UIWebView. Everything is working great except...

第一次播放视频时，它以〜10％的音量播放。设备音量设置为100％，播放器音量在UI中显示为100％。退出网络视图并使用我们的原生流媒体播放器在应用中播放歌曲，然后返回到播放的视频的音量正确。

The first time a video is played it plays at ~10% volume. The device volume is set at 100% and the player volume shows 100% in the UI. Backing out of the web view and play a song in the app using our native streaming player then go back to the video it plays at the correct volume.

t工作...

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [[MPMusicPlayerController applicationMusicPlayer] setVolume:1.0];
}

---

---

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [[MPMusicPlayerController iPodMusicPlayer] setVolume:1.0];
}

两个调用都只是在屏幕上刷新音量改变的UI，

Both calls just flash the volume changed UI on screen and do nothing for the WebView volume.

推荐答案

如果您有任何想法，

经过一些更多的研究，我只需要从内置的音频播放器设置回放类型。

After some more research I just needed to set the playback type back from the built in audio player.

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
BOOL ok;
NSError *setCategoryError = nil;
ok = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];

沿着这些线。
