内容顶部的IOS键盘建议栏

对于我的RMIT课程，我正在阅读《应用程序开发与Swift》一书，现在正在研究滚动视图

我实现了书中告诉我的代码，使滚动视图移动到键盘之外，但它没有注意到键盘顶部的建议栏，因此这肯定不理想，因为它是我试图输入文本的电话号码字段

我使用的代码如下

    func registerForKeyboardNotifications() {
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWasShown(_:)),name: .UIKeyboardDidShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillBeHidden(_:)), name: .UIKeyboardWillHide, object: nil)
}

@objc func keyboardWasShown(_ notification: NSNotification) {
    guard let info = notification.userInfo,
        let keyboardFrameValue = info[UIKeyboardFrameBeginUserInfoKey] as? NSValue
        else {return}
    let keyboardFrame = keyboardFrameValue.cgRectValue
    let keyboardSize = keyboardFrame.size

    let contentInsets = UIEdgeInsetsMake(0.0, 0.0, keyboardSize.height, 0.0)
    scrollView.contentInset = contentInsets
    scrollView.scrollIndicatorInsets = contentInsets
}

@objc func keyboardWillBeHidden(_ notification: NSNotification) {
    let contentInsets = UIEdgeInsets.zero
    scrollView.contentInset = contentInsets
    scrollView.scrollIndicatorInsets = contentInsets
}

我想知道这段代码是否是在建议栏出现之前编写的，是否有一种新的方法包括建议栏。

用

UIKeyboardFrameEndUserInfoKey

替换此键

UIKeyboardFrameEndUserInfoKey
