如何在播放音乐时振动 iPhone
我尝试在使用 MediaPlayer 框架播放 iPod 音乐时使用 AudioServicesPlaySystemSound(kSystemSoundID_Vibrate) 振动 iPhone，但在播放音乐时无法让振动工作。我可以使用以下代码在播放 iPod 音乐的同时播放声音，但振动似乎不起作用。
[musicPlayerController play]; // play the iPod music
AudioServicesPlaySystemSound(mySoundFileID); // this function works fine -- it plays an aif sound while the music is playing
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); // But this line doesn't do anything!
有人对我有什么建议吗？多谢！
I am trying to vibrate the iPhone using AudioServicesPlaySystemSound(kSystemSoundID_Vibrate) while playing iPod music with the MediaPlayer framework, but I can't get the vibrate to work while the music is playing. I can play a sound at the same time as the iPod music using the following code, but the vibrate doesn't seem to work.
[musicPlayerController play]; // play the iPod music
AudioServicesPlaySystemSound(mySoundFileID); // this function works fine -- it plays an aif sound while the music is playing
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); // But this line doesn't do anything!
Does anyone have any suggestions for me? Thanks a lot!

你检查过iphone设置中的声音设置吗？您需要将声音下的振动更改为“开”，以防其关闭。
Have you checked the sound setting in iphone setting? You need to changed vibrate to ON under sounds, in case it turned OFF.
