How do I apply mask to a UITextField ? I found some ways to apply a mask to a UITextField , but it did not seem to me to be a very correct thing to do. It could be an example of a simple phone mask. It can be in Swift or Objective-C.
OBS: a way that does not look like a "gambiarra"
You can use VMaskTextField where you just have to enter a mask to take on the formatting.
For example:
self.maskTextField.mask = @"(##) ####-####";
Other examples:
You need to implement the "shouldChangeCharactersInRange" method of TextField.
Inside the method applies the validation of the text that you want whenever there is a change in the text. A great solution I've come to use , allows you to easily apply a reg the text to get that same formatted text.
Analyze the code and apply your needs
