ios後台播放

iphone上邊後台運行修改設定檔 添加Required background modes

然後再程式裡適當的位置調用如下代碼

-(void)activeBackGroundPlayer{    /**/    [[AVAudioSession sharedInstance] setDelegate: self];    [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: nil];    UInt32 doSetProperty = 0;    AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryMixWithOthers,sizeof (doSetProperty),&doSetProperty);    NSError *activationError = nil;    [[AVAudioSession sharedInstance] setActive: YES error: &activationError];  }

播放器類 繼承

UIApplicationDelegate

最後建立播放器的時候設定委託到self就可以了

player = [[AVAudioPlayer alloc]initWithContentsOfURL:fileURL error:nil];        [player prepareToPlay];        [player setDelegate:self];        [player play];
