将Interface Builder中的UITextField连接到代码中定义的IBOutlet

Question

Any idea why IB doesn't let me make this connection?

Answer 1

In the Identity Inspector for that views File's Owner, make sure that the Class is set to MainScreenViewController . If you could add a screenshot of your MainScreenViewController.xib window that may be more helpful.

Answer 2

You are trying to link two different IB documents, ie two different .xib files, which is not possible. I think you really only want to have one .xib file here.
