更改AudioServicesPlaySystemSound（kSystemSoundID_Vibrate）的持续时间 [英] Change the duration of AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)

问题描述

我使用 AudioServicesPlayAlertSound（kSystemSoundID_Vibrate）;

如何选择振动的持续时间？

How can I choose the duration of the vibration?

我只想要一个短暂的震动，就像敲击键盘按钮的点击。

I want only one short vibration, like the "click" from tapping a keyboard button.

推荐答案

如文章，并在此主题，有一种方法可以调整振动的持续时间，默认为0.4秒的振动和0.1秒的静音。

As explained in this article and in this topic, there is a way to adjust the time duration of the vibration, which by default is 0.4 seconds of vibration and 0.1 seconds of silence.

for (int i = 1; i < 60; i++) { 
    [self performSelector:@selector(vibe:) withObject:self afterDelay:i *.3f];
}

选择器：

-(void)vibe:(id)sender {
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
