AudioSessionSetProperty在IOS 7.0弃用因此如何设置kAudioSessionProperty_OverrideCategoryMixWithOthers

Question

需要非过时替代品（顺便说一句，我认为这仍然是在link目前苹果文档）：

OSStatus propertySetError = 0; 
UInt32 allowMixing = true; 

propertySetError = AudioSessionSetProperty (
         kAudioSessionProperty_OverrideCategoryMixWithOthers, // 1 
         sizeof (allowMixing),         // 2 
         &allowMixing           // 3 
        ); 

感谢;

使用AVAudioSession：

AVAudioSession *session = [AVAudioSession sharedInstance]; 

NSError *setCategoryError = nil; 
if (![session setCategory:AVAudioSessionCategoryPlayback 
     withOptions:AVAudioSessionCategoryOptionMixWithOthers 
     error:&setCategoryError]) { 
    // handle error 
}
