iOS Suck at IB, app is crashing when tab is selected. I know its IB related

[dalearyous]

i have an app that has 3 tabs at the bottom and the first two work. the third tab is basically an exact copy of the 2nd tab only its searching different array.

i know it is interface builder. i suck at it and always find it confusing. will anyone take a look at my project? extremely stuck.

Post Console code, so we know what makes it crash.
I think the most obvious thing is, open the mainwindow, press the (second tab for example.)
open the Identity inspector, check out the CLASS name, and change it to the SecondViewController or whatever u have as the controller of the XIB. then at the first tab, check out the NIB it should be loading. This is the most common error..
