在swift 5中，这就是如何捕捉运动并进行检查

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

首先，我知道这是一个老帖子，但它仍然是相关的，我发现投票最高的两个答案并没有尽早检测到震动。下面是如何做到这一点:

将CoreMotion链接到目标构建阶段的项目: 在你的ViewController中: - (BOOL)canBecomeFirstResponder { 返回YES; ｝ - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event ｛ if(运动== UIEventSubtypeMotionShake) { //检测到震动。 ｝ ｝

一个基于第一个答案的swif挑逗版本!

override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
    if ( event?.subtype == .motionShake )
    {
        print("stop shaking me!")
    }
}

这是你需要的基本委托代码:

#define kAccelerationThreshold      2.2

#pragma mark -
#pragma mark UIAccelerometerDelegate Methods
    - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration 
    {   
        if (fabsf(acceleration.x) > kAccelerationThreshold || fabsf(acceleration.y) > kAccelerationThreshold || fabsf(acceleration.z) > kAccelerationThreshold) 
            [self myShakeMethodGoesHere];   
    }

也在接口中的适当代码中设置。即:

@interface MyViewController: UIViewController <UIPickerViewDelegate, UIPickerViewDataSource, UIAccelerometerDelegate>

在swift 5中，这就是如何捕捉运动并进行检查

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

为了在整个应用范围内启用这个功能，我在UIWindow上创建了一个类别:

@implementation UIWindow (Utils)

- (BOOL)canBecomeFirstResponder
{
    return YES;
}

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if (motion == UIEventSubtypeMotionShake) {
        // Do whatever you want here...
    }
}
