That's not what was happening, but you may be on to something.
If you name an outlet 'textField', then the nib loading machinery will look for a method called -setTextField: in order to wire the outlet. That's probably going to fail in quite a few cases because the name is far too generic and it's not unlikely that a method called -setTextField: exists that has nothing to do with said outlet. The wiring up will fail if that method does not in fact simply assign the outlet.
It's a really good idea to name your outlets in some fashion that indicates both their type and their function. If nothing else it makes identifying them in IB easier, for example, a good name might be 'mCountOfWidgetsTextField'.
This name tells you a) that it's a data member of the class - 'm' for member, b) that it represents 'countOfWidgets' and c) that it is expected to be a text field. It also means that accidentally misleading the nib loader is far less likely.
It's certainly worth trying a better, less generic name and see if that fixes your issue.
