iOS音頻播放器靜音切換音頻會話的IOS

Question

如何在ios中靜音音頻播放器？主頁按鈕被按下時是否靜音？還有如何爲ios設置音頻會話？

Answer 1

爲靜音

[timeraudioPlayer setVolume:0.0]; 

對於音頻會話

AVAudioSession *audioSession = [AVAudioSession sharedInstance]; 
    NSError *err = nil; 
    [audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err]; 
    if(err) 
    { 
     NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]); 
     return; 
    } 
    [audioSession setActive:YES error:&err]; 
    err = nil; 
    if(err){ 
     NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]); 
     return; 
    }
