Remove @“” from NSString or typecast NSString into variable name

Question

I read a NSString from file and then I want to #define this as a UIColor so I can quickly change color\'s.

I want something to work like so:

#define GRAY         


        

Answer 1

You could load the colors into a NSDictionary.

// Put this in some global scope
NSDictionary *colors = [NSDictionary dictionaryWithObjectsAndKeys: 
    [UIColor darkGrayColor], @"GRAY", nil];

// using the dictionary
myController.view.backgroundColor = [colors objectForKey:kColor];
