自定义一个Animation类继承UIWindow

由于获知手机摇动是结合硬件的底层东西，所以要直接在appdelegate里面自定义一个window，这也是Animation这个类的用途。

下面开始讲述代码：

在AppDelegate.h文件里面导入Animation头文件声明一个aWindow

然后在AppDelegate.m文件中的

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中实现你写的界面例如：

   self.aWindow=[[[Animation alloc]initWithFrame:[[UIScreen mainScreen]bounds] ]autorelease];
    
    // Override point for customization after application launch.
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease];
    } else {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease];
    }
    UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:self.viewController];
    nav.navigationBarHidden=YES;

    [self.aWindow addSubview:nav.view];
    [self.aWindow makeKeyAndVisible];

然后介绍Animation类的内容：

在.h文件中声明一个协议方法-(void)AnimateOnePhone;

在.m文件中引用系统的两个接收震动手机的方法

-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    NSLog(@"--------开始摇一摇-------");
}
-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if (motion==UIEventSubtypeMotionShake) {
        [[NSNotificationCenter defaultCenter]postNotificationName:@"StartAnimate" object:self];
    }
}

最后在你所需要接受摇动手机信息的界面作如下操作：

导入头文件

#import<QuartzCore/QuartzCore.h>
#import <AudioToolbox/AudioToolbox.h>

声明一个SystemSoundID soundID;

在- (void)viewDidLoad中写如下代码接受通知

     NSString *path = [[NSBundle mainBundle] pathForResource:@"glass" ofType:@"wav"];
    AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:path], &soundID);
    
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(addAnimations) name:@"StartAnimate" object:nil];

自定义一个调用方法

#pragma mark - 摇一摇动画效果
- (void)addAnimations
{
    AudioServicesPlaySystemSound (soundID);
    
    //让imgup上下移动
    CABasicAnimation *translation2=[CABasicAnimation animationWithKeyPath:@"position"];
    translation2.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    //以图片的中心算起的坐标
    translation2.fromValue=[NSValue valueWithCGPoint:CGPointMake(160, 115)];
    translation2.toValue=[NSValue valueWithCGPoint:CGPointMake(160, 40)];
    translation2.duration=0.5;
    translation2.repeatCount=1;
    translation2.autoreverses=YES;
    
    //让imagdown上下移动
    CABasicAnimation *translation = [CABasicAnimation animationWithKeyPath:@"position"];
    translation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    //以图片的中心算起的坐标
    translation.fromValue = [NSValue valueWithCGPoint:CGPointMake(160, 345)];
    translation.toValue = [NSValue valueWithCGPoint:CGPointMake(160, 420)];
    translation.duration = 0.5;
    translation.repeatCount = 1;
    translation.autoreverses = YES;
    
    [bottomImg.layer addAnimation:translation forKey:@"translation"];
    [upImg.layer addAnimation:translation2 forKey:@"translation2"];
    
    
}
