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。 ｝ ｝

I came across this post looking for a "shaking" implementation. millenomi's answer worked well for me, although i was looking for something that required a bit more "shaking action" to trigger. I've replaced to Boolean value with an int shakeCount. I also reimplemented the L0AccelerationIsShaking() method in Objective-C. You can tweak the ammount of shaking required by tweaking the ammount added to shakeCount. I'm not sure i've found the optimal values yet, but it seems to be working well so far. Hope this helps someone:

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
    if (self.lastAcceleration) {
        if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7] && shakeCount >= 9) {
            //Shaking here, DO stuff.
            shakeCount = 0;
        } else if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7]) {
            shakeCount = shakeCount + 5;
        }else if (![self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.2]) {
            if (shakeCount > 0) {
                shakeCount--;
            }
        }
    }
    self.lastAcceleration = acceleration;
}

- (BOOL) AccelerationIsShakingLast:(UIAcceleration *)last current:(UIAcceleration *)current threshold:(double)threshold {
    double
    deltaX = fabs(last.x - current.x),
    deltaY = fabs(last.y - current.y),
    deltaZ = fabs(last.z - current.z);

    return
    (deltaX > threshold && deltaY > threshold) ||
    (deltaX > threshold && deltaZ > threshold) ||
    (deltaY > threshold && deltaZ > threshold);
}

PS: 我将更新间隔设置为1/15秒。

[[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0 / 15)];

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。 ｝ ｝

我最终使用撤销/重做管理器教程中的代码示例使其工作。 这正是你需要做的:

在应用的委托中设置applicationSupportsShakeToEdit属性:

    - (void)applicationDidFinishLaunching:(UIApplication *)application {

        application.applicationSupportsShakeToEdit = YES;

        [window addSubview:viewController.view];
        [window makeKeyAndVisible];
}

在视图控制器中添加/重写canBecomeFirstResponder, viewDidAppear:和viewWillDisappear:方法:

-(BOOL)canBecomeFirstResponder {
    return YES;
}

-(void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [self becomeFirstResponder];
}

- (void)viewWillDisappear:(BOOL)animated {
    [self resignFirstResponder];
    [super viewWillDisappear:animated];
}

添加motionEnded方法到你的视图控制器:

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if (motion == UIEventSubtypeMotionShake)
    {
        // your code
    }
}

在ViewController中添加以下方法。M文件，它的工作正常

    -(BOOL) canBecomeFirstResponder
    {
         /* Here, We want our view (not viewcontroller) as first responder 
         to receive shake event message  */

         return YES;
    }

    -(void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
    {
            if(event.subtype==UIEventSubtypeMotionShake)
            {
                    // Code at shake event

                    UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Motion" message:@"Phone Vibrate"delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
                    [alert show];
                    [alert release];

                    [self.view setBackgroundColor:[UIColor redColor]];
             }
    }
    - (void)viewDidAppear:(BOOL)animated
    {
             [super viewDidAppear:animated];
             [self becomeFirstResponder];  // View as first responder 
     }

抱歉把这篇文章作为一个答案而不是评论，但正如你所看到的，我是Stack Overflow的新手，所以我还没有足够的声誉来发表评论!

不管怎样，我第二个@cire关于确保设置第一响应器状态一旦视图是视图层次结构的一部分。例如，在视图控制器viewDidLoad方法中设置第一响应器状态是行不通的。如果你不确定它是否工作，[view becomeFirstResponder]返回一个你可以测试的布尔值。

另一点:如果你不想创建一个不必要的UIView子类，你可以使用一个视图控制器来捕获抖动事件。我知道没有那么麻烦，但还是有选择的。只是移动Kendall放入UIView子类的代码片段到你的控制器并发送becomeFirstResponder和resignFirstResponder消息给self而不是UIView子类。
