判断手势事件向左还是向右

首先在view上添加手势 UIPanGestureRecognizer

1 UIPanGestureRecognizer *panGes = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(goAnimation:)];2 3  [self.view addGestureRecognizer:panGes];

 


在滑动方法当中根据 translationInView 这个方法返回的点的正负来判断向左还是向右 大于0说明向左,小于0说明向右 

UIPanGestureRecognizer *pan = (UIPanGestureRecognizer *)sender;CGPoint point = [pan translationInView:self.view];if (point.x>0) {    //向左滑动}else{    //向右滑动}
