最近在做一個類似手機來電一樣的讓手機無線震動的功能。蘋果官方給出的介面很簡單總結起來就兩步：

1.往專案中匯入AudiToolbox.framework框架

2.就一句程式碼：

AudioServicesPlaySystemSound (kSystemSoundID_Vibrate);

可以實現震動，但是就那麼以下，我試了使用NStimer來實現不停的震動，可以實現，但是要暫停下來就麻煩了。

在網上搜了些資料，雖然說出了原理，但是具體的實現程式碼還是有點讓人看不懂。以下是我自己總結的寫出來的Demo程式碼，思路清晰簡單，而且拷入工程就能用，不羅嗦直接上程式碼：

    [super viewDidLoad];
    //建立震動開始按鈕
    UIButton *startBtn_c=[[UIButton alloc]initWithFrame:CGRectMake(180, 200, 100, 44)];
    startBtn_c.backgroundColor=[UIColor blueColor];
    [startBtn_c setTitle:@"開始-C" forState:UIControlStateNormal];
    [startBtn_c addTarget:self action:@selector(startButton_cClickedAction) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:startBtn_c];
    //建立震動暫停按鈕
    UIButton *stopBtn_c=[[UIButton alloc]initWithFrame:CGRectMake(40, 200, 100, 44)];
    stopBtn_c.backgroundColor=[UIColor redColor];
    [stopBtn_c setTitle:@"暫停-C" forState:UIControlStateNormal];
    [stopBtn_c addTarget:self action:@selector(stopButton_cClickedAction) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:stopBtn_c];
    // Do any additional setup after loading the view, typically from a nib.
}
