如何使MPMoviePlayerController忽略静音开关

Question

我想播放一个视频,MPMoviePlayerController但我希望它忽略静音开关,类似于Youtube视频播放器的行为.

有任何想法吗？

Answer 1

使用该AVAudioSession类别AVAudioSessionCategoryPlayback,您的应用将忽略静音开关,如Youtube应用.

例如(在评论中受到Ken Pletzer的启发):

#import <AVFoundation/AVFoundation.h>

// note: you also need to add AVfoundation.framework to your project's 
// list of linked frameworks
NSError *error = nil;
BOOL success = [[AVAudioSession sharedInstance] 
                setCategory:AVAudioSessionCategoryPlayback 
                error:&error];
if (!success) {
    // Handle error here, as appropriate
}
