Why not simply... [self doSomething] ?

Why not simply [otherClass doSomethingElse] ?
...aka... Why are you using performSelector in the above?

You are sending a message to an object that doesn't respond to that message
(aka no implementation for it). The error message you listed should have
more information about the class of the object you messaged incorrectly,
what does the rest of it say?
Hard to tell what may be going wrong with the limited information you have
posted. I rather not waste time guessing (can think of at least 4 common
things you could be doing wrong).
