ios - 快速处理键盘重叠

Question

在没有 IQKeyboardManagerSwift 或 IHKeyboardAvoiding 等框架的情况下，修复键盘重叠的最佳方法是什么？

Answer 1

设置 ScrollView 底部布局约束，

这使得所有文本字段都可以通过滚动使用，您无需考虑其他设备和键盘高度差异。

@IBOutlet weak var mainScrollViewBottomConstraint: NSLayoutConstraint!

 open override func viewDidLoad() {
        super.viewDidLoad()
        let notificationCenter = NotificationCenter.default
        notificationCenter.addObserver(self, selector: #selector(keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

         notificationCenter.addObserver(self, selector: #selector(keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
    }

    func keyboardWillShow(_ notification: Notification) {
        let userInfo = (notification as NSNotification).userInfo!
        let keyboardSize = (userInfo[UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
        mainScrollViewBottomConstraint.constant = keyboardSize.height
    }

    func keyboardWillHide(_ notification: Notification) {
        mainScrollViewBottomConstraint.constant = 0
    }
