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 
     }

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>

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...
    }
}

@end

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3.0，现在有一个更简单的方法-挂钩到新的运动事件。

主要的技巧是你需要有一些UIView(不是UIViewController)你想要作为firstResponder来接收震动事件消息。这是你可以在任何UIView中使用的代码来获取震动事件:

@implementation ShakingView

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if ( event.subtype == UIEventSubtypeMotionShake )
    {
        // Put in code here to handle shake
    }

    if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )
        [super motionEnded:motion withEvent:event];
}

- (BOOL)canBecomeFirstResponder
{ return YES; }

@end

你可以很容易地将任何UIView(甚至是系统视图)转换为一个视图，只需用这些方法子类化视图(然后选择这个新类型而不是IB中的基类型，或者在分配视图时使用它)就可以获得抖动事件。

在视图控制器中，你想要将这个视图设置为第一响应器:

- (void) viewWillAppear:(BOOL)animated
{
    [shakeView becomeFirstResponder];
    [super viewWillAppear:animated];
}
- (void) viewWillDisappear:(BOOL)animated
{
    [shakeView resignFirstResponder];
    [super viewWillDisappear:animated];
}

不要忘记，如果你有其他视图成为用户操作的第一响应器(如搜索栏或文本输入字段)，当其他视图退出时，你还需要恢复震动视图的第一响应器状态!

即使您将applicationSupportsShakeToEdit设置为NO，此方法也有效。

在我的Diceshaker应用中:

// Ensures the shake is strong enough on at least two axes before declaring it a shake.
// "Strong enough" means "greater than a client-supplied threshold" in G's.
static BOOL L0AccelerationIsShaking(UIAcceleration* last, UIAcceleration* current, 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);
}

@interface L0AppDelegate : NSObject <UIApplicationDelegate> {
    BOOL histeresisExcited;
    UIAcceleration* lastAcceleration;
}

@property(retain) UIAcceleration* lastAcceleration;

@end

@implementation L0AppDelegate

- (void)applicationDidFinishLaunching:(UIApplication *)application {
    [UIAccelerometer sharedAccelerometer].delegate = self;
}

- (void) accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {

    if (self.lastAcceleration) {
        if (!histeresisExcited && L0AccelerationIsShaking(self.lastAcceleration, acceleration, 0.7)) {
            histeresisExcited = YES;

            /* SHAKE DETECTED. DO HERE WHAT YOU WANT. */

        } else if (histeresisExcited && !L0AccelerationIsShaking(self.lastAcceleration, acceleration, 0.2)) {
            histeresisExcited = NO;
        }
    }

    self.lastAcceleration = acceleration;
}

// and proper @synthesize and -dealloc boilerplate code

@end

组织性可以防止震动事件多次触发，直到用户停止震动。
