You should use the opaque type CGColorRef instead of UIColor on your struct. Then, in the CocoaTouch portion of your code you could get a UIColor instance like this:

UIColor *color = [UIColor colorWithCGColor:colorRef];

I saves you some hassle if you follow that advice of not mixing structs and objects. That leaves you with two possibilities:

  1. Using Objective-C objects: Make "LevelMeterColorThreshold" a class with two properties instead of a struct.
  2. Use C structs and C primitives: Instead of "UIColor" use three floats red/green/blue - if that is sufficient. Then you can reconstruct a UIColor later on.

I probably would pick #1.
