I started creating a simple iOS app that does some operations.
But I'm having some problems when the keyboard appears, hiding one of my textfields.
I think it's a common problem and I did some research but I couldn't find anything that solved my problem.
I want to use a ScrollView rather than animate the textfield to make it visible.
In ViewDidLoad, register the notifications:
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name:UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name:UIResponder.keyboardWillHideNotification, object: nil)
Add below observer methods which does the automatic scrolling when keyboard appears.
@objc func keyboardWillShow(notification:NSNotification) {
guard let userInfo = notification.userInfo else { return }
var keyboardFrame:CGRect = (userInfo[UIResponder.keyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
keyboardFrame = self.view.convert(keyboardFrame, from: nil)
var contentInset:UIEdgeInsets = self.scrollView.contentInset
contentInset.bottom = keyboardFrame.size.height + 20
scrollView.contentInset = contentInset
}
@objc func keyboardWillHide(notification:NSNotification) {
let contentInset:UIEdgeInsets = UIEdgeInsets.zero
scrollView.contentInset = contentInset
}
