我可以使用AVAudioPlayer振動播放聲音嗎？

Question

我讓AVAudioPlayer在聊天過程中播放聲音以發出消息警報，我也希望手機振動。 是否可以在AVAudioPlayer中執行此操作，或者我需要使用其他方法？

謝謝

播放聲音：

NSString *source = [[NSBundle mainBundle] pathForResource:@"beep" ofType:@"mp3"];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:source] error:nil];
self.audioPlayer.delegate = self;
self.audioPlayer.numberOfLoops = 0;
self.audioPlayer.volume = 1.0; 
[self.audioPlayer play];

Swift 2.2版本：

var source = NSBundle.mainBundle().pathForResource("beep", ofType: "mp3")!
do {
    audioPlayer = try AVAudioPlayer(contentsOfURL: NSURL.fileURLWithPath(source))
}
catch let error {
    // error handling
}
audioPlayer.delegate = self
audioPlayer.numberOfLoops = 0
audioPlayer.volume = 1.0
audioPlayer.play()

Swift 3.0版本：

var source = Bundle.main.path(forResource: "beep", ofType: "mp3")!
do {
    audioPlayer = try AVAudioPlayer(contentsOfURL: URL(fileURLWithPath: source))
}
catch {
    // error handling
}
audioPlayer.delegate = self
audioPlayer.numberOfLoops = 0
audioPlayer.volume = 1.0
audioPlayer.play()

振動：

AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);

振動在Audiotoolbox.framework而播放聲音在AVFoundation.framework 。

請注意，某些設備（iPod Touch）無法振動，這將無法正常工作。
