iOS 16 中通过 UIPasteboard 获取剪贴板中的内容时，系统会弹出对话框提醒用户是否允许粘贴。如果不想显示该对话框，建议使用新增的 UIPasteControl 控件来读取剪贴板的内容。
// Created by YungFan
import UIKit
class ViewController: UIViewController {
lazy var textField: UITextField = {
let textField = UITextField(frame: CGRect(x: 20,
y: 200,
width: UIScreen.main.bounds.width - 40,
height: 40))
textField.borderStyle = .roundedRect
return textField
}()
// UIPasteControl
lazy var pasteControl: UIPasteControl = {
// 创建配置
let config = UIPasteControl.Configuration()
// 背景色
config.baseBackgroundColor = .orange
// 图标与文字颜色
config.baseForegroundColor = .green
// 形状
config.cornerStyle = .capsule
// 显示模式
config.displayMode = .iconAndLabel
// 创建UIPasteControl
let pasteControl = UIPasteControl(configuration: config)
// 设置target，获取剪切板内容后粘贴的位置
pasteControl.target = textField
pasteControl.frame = CGRect(x: 0, y: 0, width: 200, height: 60)
pasteControl.center = view.center
return pasteControl
}()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(textField)
view.addSubview(pasteControl)
}
}
注意：当剪贴板为空时，该按钮处于禁用状态。
