Question

在我的loginViewController上，有一个 textField 和按钮用于搜索。我想确保在textField中输入文本时，我的界面没有被键盘覆盖，而是滚动到该键盘的大小并且可以访问所有元素。为此，我编写了以下代码：

override func viewDidLoad() {
        super.viewDidLoad()

        NotificationCenter.default.addObserver(self, selector: #selector(kbDidShow), name: NSNotification.Name.UIKeyboardDidShow, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(kbDidHide), name: NSNotification.Name.UIKeyboardDidHide, object: nil)
    }

    @objc func kbDidShow(notification: Notification) {
        guard let userInfo = notification.userInfo else { return }
        let kdFrameSize = (userInfo[UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
        (self.view as! UIScrollView).contentSize = CGSize(width: self.view.bounds.size.width, height: self.view.bounds.size.height + kdFrameSize.height)
        (self.view as! UIScrollView).scrollIndicatorInsets = UIEdgeInsets(top: 0, left: 0, bottom: kdFrameSize.height, right: 0)
    }

    @objc func kbDidHide() {
        (self.view as! UIScrollView).contentSize = CGSize(width: self.view.bounds.size.width, height: self.view.bounds.size.height)
    }

运行应用程序时，我具有滚动条的侧视图，但是界面本身不滚动。可能是什么问题？

尝试使用IQKeyboardManager，这将自动完成您的工作链接-https://github.com/hackiftekhar/IQKeyboardManager

您只需要在AppDelegate中添加此行在每个视图中，所有文本字段都会自动调整。

IQKeyboardManager.sharedManager().enable = true

更改内容偏移，而不是设置contentSize。

 @objc func kbDidShow(notification: Notification) {
    guard let userInfo = notification.userInfo else { return }
    let kdFrameSize = (userInfo[UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
    (self.view as! UIScrollView).contentOffset.y +=  kdFrameSize.size.height
    (self.view as! UIScrollView).scrollIndicatorInsets = UIEdgeInsets(top: 0, left: 0, bottom: kdFrameSize.height, right: 0)
}

SWIFT键盘与内容重叠
