ios - Call a function while the phone is being shaken

Question

I'm making an app that uses motionBegan to call a function. However it just call my function once when I shake my phone, then once more if I stop and shake it again. While I want to have the func active as long as I'm shaking the phone. Any ideas what I should do ?

尝试这个：

迅速：

override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
        if motion == .motionShake {
            print("Device Shaked")
        }
}

Objective-C

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if (event.type == UIEventSubtypeMotionShake)
    {        
        NSLog(@"Device Shaked") ;
    }
}
