    在我们的iOS里面本身就有实现微信功能摇一摇功能的方法,我们只需要在进行摇一摇 操作时调用相应的方法,就可以了。 //如何实现微信的摇一摇功能 //在 UIResponder中存在这么一套方法 - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0); - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0); - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0); //这就是执行摇一摇的方法。那么怎么用这些方法呢? //很简单,你只需要让这个Controller本身支持摇动 //同时让他成为第一相应者: - (void)viewDidLoad { [superviewDidLoad]; // Do any additional setup after loading the view, typically from a nib. [[UIApplicationsharedApplication] setApplicationSupportsShakeToEdit:YES]; [selfbecomeFirstResponder]; } //然后去实现那几个方法就可以了 - (void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { //检测到摇动 } - (void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event { //摇动取消 } - (void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { //摇动结束 if (event.subtype == UIEventSubtypeMotionShake) { //something happens } }
