问题描述
我需要在我的iPhone应用程序中循环播放一个.caf文件。
I need to loop play a .caf file in my iPhone app.
AVAudioPlayer看起来很有前途。但有一个问题。即使我按下了iPhone上的静音按钮，它也不会停止或静音。
The AVAudioPlayer looks promising. But there's one problem. It won't stop or mute even if I pressed the mute button on the iPhone.
我明白，没有办法以编程方式找出该静音按钮是在iOS 5中按下或不按。
And I understand that there would be no way to programmatically find out whether that mute button is pressed or not in iOS 5.
所以，我需要知道的可能是关于AVAudioPlayer或AVAudioSession的一些属性。
So, what I need to know might be some properties about AVAudioPlayer or AVAudioSession. Or, perhaps, I may need to consider other libraries to loop playing my .caf file.
任何想法？
推荐答案
我意识到这是因为我有这行代码
I realized it was because I had this line of code
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: nil];
然后我将其更改为
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil];
然后静音按钮会工作并停止我的AVAudioPlayer ...
Then the mute button would work and stop my AVAudioPlayer...
