Error 'CGContextSetBlendMode' & 'CGContextSetStrokeColorWithColor'

Hi guys,

I just notice that these errors appear in the xcode console. Sounds important, as it says “this is a serious error”…

In brief, my code is a storyboard containing a ‘newTextField’ and some ‘checkboxes’. Haven’t got time to pin it down yet. Hoping someone could a give some heads-up whether this error is worth-while looking into.

Device : iPad ios 7.0.2

xcode : 5.0 (5A1413)

Thanks
