Answer 1

There is no builtin conversion from a hexadecimal string to a UIColor (or CGColor) that I'm aware of. However, you can easily write a couple of functions for this purpose - for example, see http://arstechnica.com/apple/guides/2009/02/iphone-development-accessing-uicolor-components.ars.

Answer 2

I've found the simplest way to do this is with a macro. Just include it in your header and it's available throughout your project.

#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
