我正在尝试向 UITableView 中的节页脚添加一个可点击的按钮以及一些文本。我想获得与 iOS 设置应用程序完全相同的结果(如屏幕截图中的“了解更多...”按钮)。
有人知道苹果是怎么做到的吗?

抱歉,我添加的屏幕截图可能有点误导,因为我在按住按钮以使其更加突出时。这就是页脚实际的样子:
我尝试实现 titleForFooterInSection,然后将手势识别器添加到 willDisplayFooterView 中的标准页脚标签,但在初始调用时标签为 nil。我不确定这是否是一个好方法..
override func tableView(_ tableView: UITableView, titleForFooterInSection section: Int) -> String? {
return NSLocalizedString("This is some random text.", comment: "") + NSLocalizedString("Refresh", comment: "")
}
override func tableView(_ tableView: UITableView, willDisplayFooterView view: UIView, forSection section: Int) {
guard let label = view.subviews[1].subviews.first as? UILabel else {
return
}
let text = label.text!
let underlineAttriString = NSMutableAttributedString(string: text)
let range = (text as NSString).range(of: NSLocalizedString("Refresh", comment: ""))
underlineAttriString.addAttribute(.foregroundColor, value: UIColor.blue, range: range)
label.attributedText = underlineAttriString
view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(refreshTapped)))
}
Jsut 使用 viewForHeaderInSection
override func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return 150
}
override func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let header = UIView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 150));
header.backgroundColor = UIColor.groupTableViewBackground
let label = UILabel.init(frame: CGRect.init(x: 10, y: 10, width: tableView.frame.width-20, height: 100))
label.text = "I tried using your code, but the footer doesn't look like the one from my screenshot. Here's what I got: Screenshot I usually work with storyboards and xibs so I don't really know how to align the text and button"
label.numberOfLines = 4
header.addSubview(label)
let button = UIButton.init(frame: CGRect.init(x: ((tableView.frame.width-100) / 2), y: 90, width: 100, height: 40))
button.setTitle("LoadMore...", for: UIControlState.normal)
button.titleLabel?.font = UIFont.systemFont(ofSize: 12)
button.setTitleColor(.black, for: UIControlState.normal)
button.backgroundColor = .white
button.clipsToBounds = true
button.layer.cornerRadius = 20
header.addSubview(button)
return header
}
