iOS搖動方法實現

標籤：

 

iOS對於搖動進行了封裝，直接可以使用MotionEvent來實現，代碼如文檔中執行個體，

 

首先設定view為firstResponder

 - (BOOL)canBecomeFirstResponder {    //預設是NO，所以得重寫此方法，設成YES     return YES;}- (void)viewDidAppear:(BOOL)animated {     [self becomeFirstResponder];}然後實現下列方法://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{}
