Hi,
Using ios11 autofill on my textfields works great, however I have a "Mobile number" field which I intend to only allow mobile numbers to be entered (ie. no letters), I have written logic in the "shouldChangeCharactersInRange" method to only allow numbers and "+" however this also blocks the autofill feature,
Is there any way to detect if the input is "autofill" and allow it to be entered,
Thanks
I had a similar issue when working with the Password Autofill feature in the iOS 12 beta. As far as I can tell, when users are inputting text, the length of the text returned in `shouldChangeCharactersInRange:replacementString:` is always 1, so I basically look for a length > 1 and assume that it has been either pasted or autofilled.
Code Block var textFieldCountWhenBeginEditing = 0
Code Block func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool { if let text = textField.text { textFieldCountWhenBeginEditing = text.count } return true } func textFieldDidChangeSelection(_ textField: UITextField) { if textField.text != nil && textField != self.mobileTextField { let text = textField.text! let difference = abs(text.count - textFieldCountWhenBeginEditing) let isTextFromSuggestion = difference > 1 && !text.isEmpty if isTextFromSuggestion { Timer.scheduledTimer(withTimeInterval: 0.2, repeats: false) { (_) in // Do something, its from autofill } } textFieldCountWhenBeginEditing = text.count } }
