ios摇一摇功能
//微信的摇一摇是怎么实现的~发现原来 ios本身就支持
//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
