Available where `Self`: `FUIStateTintableImplementation`
  • stateDidChange() Default implementation

    Default Implementation

    Should be invoked by controls, when state is changed. Technique for doing this may vary. Controls are responsible for invoking correclty.

    Declaration

    Swift

    public func stateDidChange()
  • tintColor(for:) Default implementation

    Default Implementation

    public func tintColor(for state: UIControlState) -> UIColor?

    Parameters

    state

    Tintable state as UIControlState

    Declaration

    Swift
