setValue:forUndefinedKey: issue that makes no sense UIActivityIndicatorView

In ViewController.m I am allocating a class like so:

myClass = [[MyClass alloc]init];

but when I set a breakpoint in that class it's throwing an exception before it even hits ViewDidLoad of:

[<MyClass 0x1a4a60> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key activityIndicator.'

But the thing is the class doesn't use an interface file and there is not a single UIActivityIndicatorView in the entire project. Can some please help, I have spent hours trying to address this and it makes no sense to me.

Have you checked the xib file of your ViewController to see if there is invalid outlet connection? – Valent Richie Jun 17 '13 at 15:21
Yeah, just checked. There are no invalid outlet connections. – Matt Jun 17 '13 at 15:34

Maybe try to do clean build or even delete the app first from the simulator. – Valent Richie Jun 17 '13 at 15:59
I did that, an deleted derived data. It doesn't make sense. If I comment out the line that allocates it, the app works, but if it's uncommented it crashes, despite there being no xib's and no Activity Indicators – Matt Jun 17 '13 at 16:27
Got it working. Had to delete the class completely from project and reimported and it worked. – Matt Jun 17 '13 at 16:35
wow its doing it again – Matt Jun 18 '13 at 16:47
Go to the project you imported it from, and see if it links to an activityIndicator in that project. – AMayes Jun 18 '13 at 21:26
