How to apply mask on a UITextField? I found some ways to apply a mask on a UITextField, but it did not seem to me something very correct to do. It can be an example of telephone mask, very simple. It can be in Swift or Objective-C.

Note: a way that does not look like a "gambiarra"

  • I didn’t understand your question, what do you mean by a "mask"? a regular expression to validate the text?

  • It would set a default for the Uitextfield String. Example: Phone field: (##)####-####

  • Or also example of value field: $##,##

  • 1

    For the phone case, I answered another question here. For monetary value, you can try something from here.

You can use Vmasktextfield where you just need to indicate a mask to take the format.

For example:

self.maskTextField.mask = @"(##) ####-####";

You have to implement Textfield’s "shouldChangeCharactersInRange" method.

Within the method applies the validation of the text you want whenever there is a change in the text. A great solution I came to use, allows you to easily apply a reg and text to get that same formatted text.
