UIColor-HexValues
=================
Being a small, but exquisitely-formed category on UIColor
to create color objects from hex values, and vice versa.
Usage
=====
- Add
UIColor+HexValues.h
andUIColor+HexValues.m
into the project. - Import
UIColor+HexValues.h
into the class.
Converting from hex values to UIColor
+(UIColor *)colorWithHexString:(NSString *)hexString;
- Use with
UIColor *myColor = [UIColor colorWithHexString:@"aa22cc"];
The hex string should not include a #
character. The method will check for non-hex values, or values that are not valid colors.
Converting from UIColor to hex values
+(NSString *)hexValuesFromUIColor:(UIColor *)color;
- Use with
NSString *hexValue = [UIColor hexValuesFromUIColor:[UIColor colorWithRed:0.711 green:0.773 blue:1.000 alpha:1.000];
This will return b5c5ff
.
The returned hex string does not include a #
character.
[UIColor whiteColor]
is treated as a special case, as it isn't within the RGB color space. The return value is ffffff
as would be expected, though.
Tests
