Somewhere in your code you must be doing myUIView.inputNumber = myValue
Or
On you storyboard, check all the views one of them will have an unconnected property called inputNumber

Hope this helps

Not much of a chance of us helping without some source code and tell us what your app has in it.

Just a call stack makes it pretty hard to debug.

Maybe a screen shot of the storyboard showing some properties.

 

[PhoneyDeveloper]

Your storyboard or nib has a reference to an IBOutlet named inputNumber that doesn't exist. Right click on the view controller in the storyboard/nib and the black HUD window will appear showing the IBOutlets. Remove the inputNumber IBOutlet.
