Hi everyone,

I am new to iOS programming and am lost on something.
I renamed my original UIIMAGEVIEW from “yelOrb”… which was inefficient for the real object in the end replacing a yellow orb. So I renamed it to “girlHeadView”. (Mind you, this is what I named the UIImageView that you control with arrow keys.)

Now whenever I run the program I get a stink in’ SIGABRT telling me this [in the code above].
I even renamed “girlHeadView” back to “yelOrb”.

I went through my .h & .m file, no stray word or incorrect spelling is causing this.

How am I able to fix this? I just implemented a button function to change the UIImageView (I even commented it all out to see if that caused it- still SIGABRT issue) and I can’t even run the simulator.

Thank you!

Edit: Found my problem, I had to remove and re-add the yelOrb’s image on the storyboard. Odd, but it worked. 🙂

It sounds like there’s an outlet in interface builder connecting the UIImageView to the old property name, yelOrb. Then, when the view controller’s view loads, it tries to make that connection to yelOrb which no longer exists, so you get that error.
