Geek asks and answers

Use the iOS category to create a new color.

I would like to create some new ones UIColorthat will be used in my application. RGB is slightly changed from time to time (the exact color tone is discussed)

Currently, I need to create new colors from RGB, and the code sprinkles and repeats.

Is there a better way where I can create a new color and use it through my application.

[UIColor myNewCustomRedColor]

What is the best example here - this is the category - the right choice - if so, then how? If not, this is the recommended approach.
