This doesn't really matter but why are you doing this CGContextSelectFont(context, [@"Comic Sans MS Bold" UTF8String], 24.0, kCGEncodingMacRoman); Why not just CGContextSelectFont(context, "Comic Sans MS Bold", 24.0, kCGEncodingAscii); I changed the encoding from MacRoman to Ascii since it is actually ascii. You are creating a Constant NSString with the @"" then turning around and asking it for the UTF8 representation of that, which is the same as what i just typed above.
