AudioSessionSetProperty在IOS 7.0棄用因此如何設置kAudioSessionProperty_OverrideCategoryMixWithOthers

Question

需要非過時替代品（順便說一句，我認爲這仍然是在link目前蘋果文檔）：

OSStatus propertySetError = 0; 
UInt32 allowMixing = true; 

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

感謝;

使用AVAudioSession：

AVAudioSession *session = [AVAudioSession sharedInstance]; 

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