手机振动,摇一摇,截屏

添加AudioToolbox.framework  //然后在头文件中声明 #import//声音提示
#import 
// 声音 振动
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);//振动
AudioServicesPlaySystemSound(1007);//声音

//注册通知  iOS7提供一个崭新的推送方法：UIApplicationUserDidTakeScreenshotNotification。只要像往常一样订阅即可知道什么时候截图了。
    //    注意：UIApplicationUserDidTakeScreenshotNotification 将会在截图完成之后显示。现在在截图截取之前无法得到通知。
    //    希望苹果会在iOS8当中增加 UIApplicationUserWillTakeScreenshotNotification。（只有did, 没有will显然不是苹果的风格...）
