How to get RGB values from UIColor?

Question

Im creating a color object using the following code.

curView.backgroundColor = [[UIColor alloc] initWithHue:229 saturation:40 brightness:75 alpha:1];

How can I retrieve RGB values from the created color object?

Answer 1

float* colors = CGColorGetComponents( curView.backgroundColor.CGColor );

These links provide further details:

• UIColor Reference
• CGColorGetComponents reference

Answer 2

const float* colors = CGColorGetComponents( curView.backgroundColor.CGColor );

Thanks. I had to add the const at the start of the line as it was generating a warning.
