A collection of useful Grand Central Dispatch utilities in swift
Chronos
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()
