Well, your code is sound. I do not see any errors, it looks identical to the code I use in my apps.
Maybe the names you gave the buttons or tab view didn’t stick in IB?
Maybe the hierarchy to get to the button is incorrect… did you check in IB what the order is in the MainMenu.xib (or whatever the nib is named)? You will see the correct hierarchy to your button, very usefull to troubleshoot hierarchies mistakes i find…
Let me know if that helped, otherwise we’ll have to dig deeper!
Good night.
