<Error>: CGContextSetStrokeColorWithColor: invalid context 0x0

[purkylin]

Environment: Ipad3, ios7

: CGContextSetStrokeColorWithColor: 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.

I have the same message on iOS 7 on a iPhone 5c. But it is probably the same result on any device.

I'm aware of this but I haven't found a fix yet. Pull requests would be appreciated.

I added symbol break of 'CGPostError' and dumped above log. Hope it help.
I think the issue is only happened in iOS7.

And I traced the error from below statement
titleLayer.string = [self attributedTitleAtIndex:idx];
And set NSForegroundColorAttributeName attribute string causes CG error.
