App Error : CGContextRestoreGState: invalid context 0x0

Question

Nov 16 12:34:28 123456789.local iDraw Cross[2926] : CGContextRestoreGState: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.

What does this mean?

Possibly nothing. It depends on the circumstances under which you are seeing the message. There are some Simulator bugs that can cause this message; run the app on a device and see if you get it then. If not, then forget about it. Otherwise, show your code if you want specific help.

With the 7.0.3 iPad simulator it seems to show this for me almost every time a text field becomes first responder. It's very irritating. – jrturton Nov 16 '13 at 20:39
Yes, That is what happens for me too. I cannot get it to do anything now and I don't know what to do. I also am not sure what to post for my source as I don't want too much public as its on the app store. – AwesomeUser Jan 05 '14 at 01:53

That means surface you are trying to use has zero surface size.
