swift 点击响应视图之外的地方

 

 

需求：点击红框 才 隐藏view，

现象，在touch Began 里面写的时候， 红色和蓝色框都会消失

    /// 点击containerView 之外的地方隐藏
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        
        super.touchesBegan(touches, with: event)
        if let touch = touches.first{
            let location = touch.location(in: self)
            let convertPoint = self.convert(location, to: containerView)
            if !containerView.bounds.contains(convertPoint){
                hiddendShareView()
            }
        }
    }


    /// 点击隐藏当前界面
    private func hiddendShareView() {
        UIView.animate(withDuration: 0.25, animations: {
            self.alpha = 0
            self.layoutIfNeeded()
        }) { (res) in
            self.removeFromSuperview()
        }
    }
