UIColor

public extension UIColor

UIColor extension.

  • Helper method to instantiate a UIColor object any number of ways. E.g.

    With integer literals:

    UIColor(0xF00)
UIColor(0xFF0000)
UIColor(0xFF0000FF)

    Or string literals:

    UIColor("f00")
UIColor("FF0000")
UIColor("rgb(255, 0, 0)")
UIColor("rgba(255, 0, 0, 0.15)")

    Or (preferably), if you want to be a bit more explicit:

    UIColor(.HEX(0xFF0000))
UIColor(.RGB(255, 0, 0))
UIColor(.RGBA(255, 0, 0, 0.5))

    If a provided value is invalid, the color will be white with an alpha value of 0.

    Note

    Formula for brightness derived from W3C Techniques For Accessibility Evaluation And Repair Tools, and formula for alpha-blending attributed to StackOverflow.
