Overview

Chronos is a collection of useful Grand Central Dispatch utilities. If you have any specific requests or ideas for new utilities, don't hesitate to create a new issue.

Utilities

• DispatchTimer - A repeating timer that fires according to a static interval, e.g. "Fire every 5 seconds".
• VariableTimer - A repeating timer that allows you to vary the interval between firings, e.g. "Fire according to the function interval = 2 * count."

Usage

Quick Start

CocoaPods

Add the following to your Podfile:

pod 'Chronos-Swift'

Carthage

Add the following to your Cartfile:

github "comyarzaheri/Chronos-Swift" "master"

Using a Dispatch Timer

import Chronos

var timer = DispatchTimer(interval: 0.25, closure: {
            (timer: RepeatingTimer, count: Int) in
                println("Execute repeating task here")
            })

/** Starting the timer */
timer.start(true) // Fires timer immediately

/** Pausing the timer */
timer.pause()

/** Permanently canceling the timer */
timer.cancel()

Using a Variable Timer

import Chronos

var variableTimer: VariableTimer = VariableTimer(closure: { 
            (timer: RepeatingTimer, count: Int) -> Void in
                println("Execute repeating task here")
        }) {(timer: VariableTimer, count: Int) -> Double in
                return Double(2 * count) // Return interval according to function
        }

/** Starting the timer */
timer.start(true) // Fires timer immediately

/** Pausing the timer */
timer.pause()

/** Permanently canceling the timer */
timer.cancel()
