Detecting if UIColor was created with colorWithPatternImage

Question

I have a UIColor that is passed into me. I need to detect if it is a plain color (e.g. created with colorWithRed:green:blue:alpha:) or if it is a color that was created with colorWithPatternImage.

How can I tell what kind of color a UIColor is, simple color or otherwise?

Answer 1

You should be able to use the CGColorGetPattern function with the CGColor property, and check for NULL.

if( CGColorGetPattern( myColor.CGColor ) != NULL ) {}
