ios - 添加 UIGestureRecognizer 以从左向右滑动我的 View

Question

我有一个具有不同 UIViewControllers 的 UIStoryboard，我想添加另一个 UIViewController(如仪表板)，当用户从左侧滑动 ipad 时，仪表板将出现然后当他向后滑动时，当前 View 将被恢复。

这可能吗？如果是的话，任何提示如何做到这一点或 UIGestureRecognizer 的任何好的教程？

谢谢。

Answer 1

UISwipeGestureRecognizer * swipeleft=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeleft:)];
swipeleft.direction=UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:swipeleft];

//向右滑动

UISwipeGestureRecognizer * swiperight=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swiperight:)];
swiperight.direction=UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:swiperight];

//实现手势方法

-(void)swipeleft:(UISwipeGestureRecognizer*)gestureRecognizer 
{
       //Do what you want here
}

-(void)swiperight:(UISwipeGestureRecognizer*)gestureRecognizer 
{
    //Do what you want here
}

试试这个。

这是上述代码的 swift 版本。

向左滑动

var swipeleft = UISwipeGestureRecognizer(target: self, action: Selector("swipeleft:"))
swipeleft.direction = .left
view.addGestureRecognizer(swipeleft)

向右滑动

var swiperight = UISwipeGestureRecognizer(target: self, action: Selector("swiperight:"))
swiperight.direction = .right
view.addGestureRecognizer(swiperight)

方法实现...

 @objc func swiperight(sender: UITapGestureRecognizer? = nil) {
        // Do what u want here
    }

 @objc func swipeleft(sender: UITapGestureRecognizer? = nil) {
        // Do what u want here
    }
