In my App, I do not use any CGContext stuff. I just have a UITextView
, UIButton
and UILabel
. Not much codes added yet. Just set the content of UITextView
by:
[self.text_view setText:@"123"];
How to resolve the error ?
I'm using Xcode 5.0 (build 5A1413), iOS 7 Simulator (64-bit Retina 4"), Mac OS X 10.8.5
