class UIColormethod

UIColor​.mappedValue()

Creates a lazily-evaluated mapped color or gradient value.

static mappedValue(
  source: UIColor | UIColor.Gradient | UIColor.ColorName,
  fn?: (
    source: UIColor | UIColor.Gradient | UIColor.MappedValue,
  ) => UIColor | UIColor.Gradient | UIColor.MappedValue,
): UIColor.MappedValue;

Notes

• Use this to derive a value that may resolve to either a UIColor or UIColor.Gradient.

Parameters

• source — A color, gradient, or color name string to use as the source.
• fn — Optional transform function; if provided, equivalent to calling .map(fn) on the result.

Return value

A UIColor.MappedValue instance.
