CGContextSetRGBFillColor requires CGFloat values for R,G,B and alpha (from 0.0 to 1.0), so you'll have to convert every component of the hex color to values between 0.0 and 1.0.. How to remove NSString Related Memory Leaks? In your case:. XCode, iPhone, WebKit Framework - What am I missing?
// R = 0xe3 / 0xff = 0.890 // G = 0xf3 / 0xff = 0.953 // B = 0xfb / 0xff = 0.984 // A = 0xff / 0xff = 1.000  CGContextSetRGBFillColor(context,0.89,0.953,0.984,1.0); 
You must convert your hex color string to r,g,b,a values like this:.
NSString  *color = @"0xe3f3fbff";  unsigned r,g,b,a;  [[NSScanner scannerWithString:[color substringWithRange:NSMakeRange(2,2)]] scanHexInt:&r]; [[NSScanner scannerWithString:[color substringWithRange:NSMakeRange(4,2)]] scanHexInt:&g]; [[NSScanner scannerWithString:[color substringWithRange:NSMakeRange(6,2)]] scanHexInt:&b]; [[NSScanner scannerWithString:[color substringWithRange:NSMakeRange(7,2)]] scanHexInt:&a];  CGContextSetRGBFillColor(context,r/255.0,g/255.0,b/255.0,a/255.0);
