Hi All,
This is a real doosey of a problem, been bugging me and now holding me back
for a week.
The app loads and runs fine - well it did until I added a UIPickerView. I've
done this before and its been fine, so I'm not sure what different with this
one, but I get two errors when I change its value.
The first is a popup exception:
Objective-C exception thrown. Name: NSInvalidArgumentException Reason:
-[__NSCFArray pickerView:titleForRow:forComponent:]: unrecognized selector
sent to instance 0xf800830
the second is in the application output:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Any and all help is gratefully received!
Thanks,
Scott
