iOS dev: How to change text in the textfield?

Question

I'm a beginner trying to create my first app. I'm trying to get the user to enter in a number into the the textfield, the app does what it does, and then the answer gets placed into the textfield itself. I'm using the storyboard to make this.

For example:

User puts '1' into textfield, 'a' gets placed in place once the user presses enter.

Thanks.

You can change the .text property, for example:

self.textField.text = [NSString stringWithFormat:@"%@a", self.textField.text];
