手势小记

一：.拖动手势
1.获取手势所在的视图

-(void)panAction:(UIPanGestureRecognizer *)gesture {

    UIView *bgView = gesture.view;//bgView就是添加手势的视图    

}

2.获取手势接触屏幕的初始坐标

-(void)panAction:(UIPanGestureRecognizer *)gesture {

    CGPoint point
= [gesture locationInView:self.view]; 

}

二：touch事件（接触屏幕时响应的事件）

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{

//获取接触屏幕时的初始坐标

    UITouch *touch = touches.anyObject;

    CGPoint point = [touch locationInView:self.view];

}
