UITextContentType.OneTimeCode in Xamarin iOS

问题

i'm trying to implement the OTC into my app. I'm doing the next:

_txtField = new UITextField()
{
   UserInteractionEnabled = true,
   TextContentType = UITextContentType.OneTimeCode
};
_txtFieldDelegate = new UITextFieldDelegate();
_txtField.Delegate = _txtFieldDelegate;

I got the SMS, but i have nothing to fill the TextField, what more i need to get this works?

回答1:

Firstly,OneTimeCode is available after iOS 12.0.So,add the following code

if (UIDevice.CurrentDevice.CheckSystemVersion(12, 0))
{
  _txtField.TextContentType = UITextContentType.OneTimeCode;          
}

And set the textField as BecomeFirstResponder after you send the request of get SMS.

 _txtField.BecomeFirstResponder();

Then the SMS code will appear on the keyboard.And it will auto fill when you click it.
