在iOS7中不推荐使用:AudioSessionSetProperty

Question

如何替换以下代码行(AudioSessionSetProperty 从iOS 7开始,不推荐使用Xcode抱怨):

    UInt32 doChangeDefaultRoute = 1;
    AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof(doChangeDefaultRoute), &doChangeDefaultRoute);

Answer 1

你会想做点什么

AVAudioSession *audioSession; // get your audio session somehow

BOOL success = [audioSession overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&error];
if(!success)
{
    NSLog(@"error doing outputaudioportoverride - %@", [error localizedDescription]);
}

此API适用于iOS 6及更新的iOS版本.
