I'm trying to build a UIColor from a comma-delimited list of values for RGB, which is "0.45,0.53,0.65", represented here by the colorConfig object...
NSScanner *scanner = [NSScanner scannerWithString:colorConfig];
[scanner setCharactersToBeSkipped:[NSCharacterSet characterSetWithCharactersInString:@"\n, "]];
float red, green, blue;
return [UIColor colorWithRed:[scanner scanFloat:&red] green:[scanner scanFloat:&green] blue:[scanner scanFloat:&blue] alpha:1];
But my color is always coming back as black. So I logged the values to my console and I'm seeing Red = -1.988804, Green = -1.988800, Blue = -1.988796
What am I doing wrong?
