iOS摇动方法实现

iOS摇动方法实现

iOS对于摇动进行了封装，直接可以使用MotionEvent来实现，代码如文档中实例，

首先设置view为firstResponder

 - (BOOL)canBecomeFirstResponder 
{//默认是NO，所以得重写此方法，设成YESreturn YES;
}- (void)viewDidAppear:(BOOL)animated 
{[self becomeFirstResponder];
}然后实现下列方法://很像TouchEvent事件- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{}- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{NSLog(@"shake");
}- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{}
