迅速4 UITableView页脚，绝对底部

Question

I a have created a footer for my UITableView like so:

let customView = UIView(frame: CGRect(x: 0, y: self.view.bounds.height - 50, width: self.view.bounds.width, height: 50))
            customView.backgroundColor = UIColor.red

            commentText = UITextField(frame: CGRect(x: 0, y: 0, width: self.view.bounds.width - 50, height: 50))
            commentText.backgroundColor = UIColor.white
            commentText.layer.borderColor = UIColor.gray.cgColor
            commentText.layer.borderWidth = 1
            commentText.borderStyle = .roundedRect
            commentText.placeholder = "Enter Comment"

            let submitButton = UIButton(frame: CGRect(x: self.tableView.bounds.width - 50, y: 0, width: 50, height: 50))
            submitButton.setTitle("Go", for: .normal)
            submitButton.backgroundColor = UIColor.blue
            submitButton.addTarget(self, action: #selector(self.submitButtonPressed(_:)), for: .touchUpInside)

            customView.addSubview(commentText)
            customView.addSubview(submitButton)

            tableView.tableFooterView = customView

and here is the result of it in the screenshot:

What I am trying to do is have the footer always at the bottom of the screen, is this possible?

Answer 1

A table view footer is always at the end of the table view, after the last row in the table view. This is true no matter how many rows are in the table view.

If you want a view that stays at the bottom of the screen and never scrolls no matter how many rows there are, then you don't want a table view footer. You simply want a view added to the bottom of the screen.

The best solution is to use a UIViewController that has your "footer view" pinned to the bottom and a table view added that fills the rest of the screen.

Answer 2

也许您可以只在屏幕视图的底部添加页脚视图，而不能将其添加为UITableView的页脚视图，因为您不希望在UITableView滚动时移动文本字段和提交按钮。

Answer 3

您可以仅将自定义视图添加到视图本身，而不是tableview。

view.addSubView(customView)
