Question

So I am fairly new to objective C and iOS programming. I am learning as I program and have a question. I am trying to modify a UITextField in my FirstViewController with my Second. How do I do this?

I have a UITextField name in FirstViewController and would like to be able to do something like firstViewController.name.text = @"new name"; inside of SecondViewController with a button and have the value changed so that if I switch tabs back to the FirstViewController I see the change has been made.

Thanks in advance for any help.

Answer 1

1、Set the FirstViewController as the delegate of SecondViewController；
2、Use NSNotificationCenter to notify the change event.
