iOS 手勢滑動事件綁定

UIGestureRecognizer 手勢響應基類
－ UITapGestureRecognizer //點擊手勢識別器，可以是點擊一次，或多次都能識別
－ UIPinchGestureRecognizer //捏合手勢識別器，用于視圖的放大縮小
－ UIRotationGestureRecognizer //旋轉手勢識別器
－ UISwipeGestureRecognizer //滑動手勢識別器，向上、下、左、右滑動
－ UIPanGestureRecognizer //拖動手勢識別器
－ UILongPressGestureRecognizer //長按手勢識別器，常見的有長按跳出一個界面用以編輯

這里演示的是

UISwipeGestureRecognizer  // 上下左右的滑動

ps: 參數詳解：self設置代理類，@selector設置事件響應，

然后要設置響應的是哪個view的手勢

這里設置的是

self.gameView

/*
 * 綁定手勢事件，上下左右
 **/
- (void)bindAction {
    UISwipeGestureRecognizer *recognizer;
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeRight)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
    [self.gameView addGestureRecognizer:recognizer];
    
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeLeft)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
    [self.gameView addGestureRecognizer:recognizer];
   
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeTop)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
    [self.gameView addGestureRecognizer:recognizer];
    
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeBottom)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];
    [self.gameView addGestureRecognizer:recognizer];
}
