When clicking a button app kills process

Basically I've created a soundboard app from another app. However i keep getting the same error and I can't understand whats wrong. I'm quite new to xcode and I've searched all over the internet for help. I'll post all information which maybe required and hopefully can get this working.

See this error message?

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0

Now look at all the IBAction methods you've listed (-pushAbout, etc.).

You'll notice that -pushBetter is not listed among them.

You need to write a -pushBetter method and wire it up to the UIButton.

---

It looks like you're somehow sending a pushBetter method call to your view controller which it is apparently not prepared for (according to your code and the error):

-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0' 

Can you to a global search for "pushBetter" and see where it is in your project??
