Objective C UIColor to NSString
ios, ios6, nsstring, objective-c, uicolor
Solution
Just expanding on the answer that @Luke linked to which creates a CGColorRef to pass to CIColor:
CGColorRef colorRef = [UIColor grayColor].CGColor;
You could instead simply pass the CGColor property of the UIColor you're working on like:
NSString *colorString = [[CIColor colorWithCGColor:[[UIColor redColor] CGColor]] stringRepresentation];
Don't forget to import the Core Image framework.
Side note, a quick and easy way to convert back to a UIColor from the string could be something like this:
NSArray *parts = [colorString componentsSeparatedByString:@" "];
UIColor *colorFromString = [UIColor colorWithRed:[parts[0] floatValue] green:[parts[1] floatValue] blue:[parts[2] floatValue] alpha:[parts[3] floatValue]];
Problem
I need to convert a UIColor to an NSString with the name of the color i.e. ``` [UIColor redColor]; ``` should become ``` @"RedColor" ``` I've already tried`[UIColor redColor].CIColor.stringRepresentation` but it causes a compiler error
