How to determine whether the colour format is RGB or BGR ?

Lets assume ,

 cgcolor = Any_UIColor.cgColor

Now , how can I determine whether components of cgcolor is in RGB or BGR sequence ? (Number of components is 4)

Or, UIColor will always be in R G B format ?!

Solution

  • You can use colorSpace property of CGColor.

    /* Return the color space associated with `color'. */

    @available(iOS 2.0, *)
public var colorSpace: CGColorSpace? { get }

    Example:

        let colorspace = UIColor.red.cgColor.colorSpace

    CGColorSpaceModel will give you the exact model of the color that you are using.

        let colorspace = UIColor.red.cgColor.colorSpace?.model
