Enable keyboard return key

Question

I would like to enable the keyboard return key only when some uitextfields are not empty. I read this question How to disable/enable the return key in a UITextField?

Is this the only way? Is it true this could cause Apple to reject the app?

Answer 1

You can use the textFieldShouldReturn: method to prevent the return key from returning.
