触摸开始消除视图

Question

我的 ViewController 中有一个视图，它占据了从底部到中间屏幕的一半屏幕。我正在使用 TouchBegan 函数来关闭视图，如果在视图内部以外的其他地方点击，一切都会正常，除了当我触摸视图顶部的 10% 时，它会在不应该关闭的时候关闭，因为触摸仍在视图内允许查看。

这是我展示 vc 的代码：

            guard let vc = storyboard?.instantiateViewController(withIdentifier: "editvc") as? EditTodoViewController else {return}
                vc.modalPresentationStyle = .custom
                present(vc, animated: true)

这是我在该 vc 中的函数：

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch = touches.first
    if touch != viewForVc {
        EditTodoViewController.textFromCellForTodo = ""
        dismiss(animated: true)
    }
}

您应该检查触摸是否不在视图中，而不是检查不同的

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch = touches.first!
    let location = touch.location(in: self.view)
    
    if (!viewForVc.bounds.contains(location)) {
        EditTodoViewController.textFromCellForTodo = ""
        dismiss(animated: true)
    }
}

如果您想在检查包含之前以编程方式更改框架，请检查下面的代码

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        let touch = touches.first!
        let location = touch.location(in: self.view)
        
        // get the frame of view + 10% height
        let viewFrame = CGRect(origin: viewForVc.frame.origin, size: CGSize(width: viewForVc.frame.size.width, height: viewForVc.frame.size.height * 1.1))
        
        if (!viewFrame.contains(location)) {
            EditTodoViewController.textFromCellForTodo = ""
            dismiss(animated: true)
        }
    }
