我是iOS开发的新手。我正在使用多个TextField和TextView的视图。我正在尝试移动视图以避免键盘隐藏编辑TextField,TextView内容。下面的代码适用于所有TextFields但是当TextView是时它不会移动视图编辑。希望你能理解我的问题。 提前谢谢。
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: .UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: .UIKeyboardWillHide, object: nil)
}
deinit {
NotificationCenter.default.removeObserver(self)
}
var keybordenabled = false
@objc func keyboardWillShow(notification: NSNotification) {
if(keybordenabled == false){
adjustInsetForKeyboardShow(show: true, notification: notification)
keybordenabled = true
}
}
@objc func keyboardWillHide(notification: NSNotification) {
keybordenabled = false
adjustInsetForKeyboardShow(show: false, notification: notification)
}
func adjustInsetForKeyboardShow(show: Bool, notification: NSNotification) {
let userInfo = notification.userInfo ?? [:]
let keyboardFrame = (userInfo[UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
let adjustment = (keyboardFrame.height * (show ? 1 : -1)) + 20
scrollView.contentInset.bottom += adjustment
scrollView.scrollIndicatorInsets.bottom += adjustment
self.view.layoutIfNeeded()
}
func textViewDidBeginEditing(_ textView: UITextView)
{
if (textView.text == "Enter comment here...")
{
textView.text = ""
textView.textColor = .black
}
textView.becomeFirstResponder()
}
func textViewDidEndEditing(_ textView: UITextView)
{
if (textView.text == "")
{
textView.text = "Enter comment here..."
textView.textColor = .lightGray
}
textView.resignFirstResponder()
}

This is work Me!
override func viewWillAppear(_ animated: Bool) {
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillDisappear), name: Notification.Name.UIKeyboardWillHide, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillAppear), name: Notification.Name.UIKeyboardWillShow, object: nil)
}
override func viewWillDisappear(_ animated: Bool) {
NotificationCenter.default.removeObserver(self)
}
@objc func keyboardWillAppear(_ notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y == 0{
self.view.frame.origin.y -= keyboardSize.height
}
}
}
@objc func keyboardWillDisappear(_ notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y != 0{
self.view.frame.origin.y += keyboardSize.height
}
}
}

@Jhon您可以使用IQKeyboard第三方库来处理文本字段和文本视图滚动键盘的外观。使用此 IQKeyboard SDK将管理所有文本字段和textView的自动滚动,同时还可以节省您的工作和时间。
