iOS 手势滑动事件绑定

UIGestureRecognizer 手势响应基类
－ UITapGestureRecognizer //点击手势识别器，可以是点击一次，或多次都能识别
－ UIPinchGestureRecognizer //捏合手势识别器，用于视图的放大缩小
－ UIRotationGestureRecognizer //旋转手势识别器
－ UISwipeGestureRecognizer //滑动手势识别器，向上、下、左、右滑动
－ UIPanGestureRecognizer //拖动手势识别器
－ UILongPressGestureRecognizer //长按手势识别器，常见的有长按跳出一个界面用以编辑

这里演示的是

UISwipeGestureRecognizer  // 上下左右的滑动

ps: 参数详解：self设置代理类，@selector设置事件响应，

然后要设置响应的是哪个view的手势

这里设置的是

self.gameView

/*   * 绑定手势事件，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];  }
