UICircularProgressRingDelegate

public protocol UICircularProgressRingDelegate: class

This is the protocol declaration for the UICircularProgressRingView delegate property

The ring will be passed to the delegate in order to keep track of multiple ring updates if needed.

  • Delegate call back, called when progress ring is done animating for current value

    Declaration

    Swift

    func finishedUpdatingProgress(forRing ring: UICircularProgressRingView)

    Parameters

    ring

    The ring which finished animating
  • didUpdateProgressValue(to:) Default implementation

    This method is called whenever the value is updated, this means during animation this method will be called in real time. This can be used to update another label or do some other work, whenever you need the exact current value of the ring during animation.

    Important:

    This is a very hot method and may be called hundreds of times per second during animations. As such make sure to only do very simple and non-intensive work in this method. Do any work that takes time will considerably slow down your application.

    • Paramater newValue: The value which the ring has updated to

    Default Implementation

    Declaration

    Swift

    func didUpdateProgressValue(to newValue: CGFloat)
