问题
I'm working on an iOS app that can display YouTube videos in a UIWebView. Everything is working great except...
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.
Things that don't work...
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[[MPMusicPlayerController applicationMusicPlayer] setVolume:1.0];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[[MPMusicPlayerController iPodMusicPlayer] setVolume:1.0];
}
Both calls just flash the volume changed UI on screen and do nothing for the WebView volume.
If you have any ideas that would be greatly appreciated.

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];
Something along those lines.
