SRCountdownTimer Pod status

This is the simple circle countdown with a configurable timer

Demo gif

Installation

The most preferable way to use this library is cocoapods. Add the following line to your Podfile:

pod 'SRCountdownTimer'

and run pod install in your terminal.

Alternatively, you can manually add the files in the SRCountdownTimer directory to your project.

Usage

Create a custom instance of SRCountdownTimer(subclass of UIView) using the storyboard or directly in the code.

You can customize different properties:

public var lineWidth: CGFloat = 2.0
public var lineColor: UIColor = .black
public var trailLineColor: UIColor = UIColor.lightGray.withAlphaComponent(0.5)

public var isLabelHidden: Bool = false
public var labelFont: UIFont?
public var labelTextColor: UIColor?
public var timerFinishingText: String?

The last(timerFinishingText) means the text that will be shown after timer expires. If nil - it'll show the current counter value(0).

Use this method to start the countdown:

public func start(beginingValue: Int, interval: TimeInterval = 1)

To pause:

public func pause()

To resume(will start from the current state of view)

public func resume()

SRCountdownTimerDelegate

@objc optional func timerDidUpdateCounterValue(newValue: Int)
@objc optional func timerDidStart()
@objc optional func timerDidPause()
@objc optional func timerDidResume()
@objc optional func timerDidEnd()
