Alright, I'll try and make this brief as possible. I wanted to a UIToolbar above my keyboard, and it took me a while to figure it out, and I eventually did, but when I tried adding function to the buttons *next* and my program would soon not compile.
The entire error message can be seen here:

@Abizern suggested I should read the . Anyways it's super late, or super early however you look at it. The updated project can be found here:ViewControllerWelcome.m
Just download the zip, and try and build and you will see what I am talking about. The error probably lies somewhere in the file.
