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 
     }

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)];

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>

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。

最简单的解决方案是为你的应用程序派生一个新的根窗口:

@implementation OMGWindow : UIWindow

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if (event.type == UIEventTypeMotion && motion == UIEventSubtypeMotionShake) {
        // via notification or something   
    }
}
@end

然后在你的应用委托中:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[OMGWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    //…
}

如果你使用的是故事板，这可能会更棘手，我不知道你在应用委托中需要精确的代码。

你需要通过accelerometer:didAccelerate: method检查加速度计，这是UIAccelerometerDelegate协议的一部分，检查这些值是否超过了震动所需的移动量的阈值。

在AppController底部的accelerometer:didAccelerate:方法中有一些不错的示例代码。m在GLPaint例子中，这个例子可以在iPhone开发者网站上找到。
