Read Swifty APIs: NSTimer for more information about this project.
You can easily schedule repeating and non-repeating timers (repeats and delays) using Timer.every
and Timer.after
:
Timer.every(0.7.seconds) {
statusItem.blink()
}
Timer.after(1.minute) {
println(“Are you still here?”)
}
You can specify time intervals with these intuitive helpers:
100.ms
1.second
2.5.seconds
5.seconds
10.minutes
1.hour
2.days
You can pass method references instead of closures:
Timer.every(30.seconds, align)
If you want to make a timer object without scheduling, use new(after:)
and new(every:)
:
let timer = Timer.new(every: 1.second) {
println(self.status)
}
(This should be defined as an initializer, but a bug in Foundation prevents this)
Call start()
to schedule timers created using new
. You can optionally pass the run loop and run loop modes:
timer.start()
timer.start(modes: .defaultRunLoopMode, .eventTrackingRunLoopMode)
If you want to invalidate a repeating timer on some condition, you can take a Timer
argument in the closure you pass in:
Timer.every(5.seconds) { (timer: Timer) in
// do something
if finished {
timer.invalidate()
}
}
Note: If you’re running Swift 2, use SwiftyTimer v1.4.1
If you’re using CocoaPods, just add this line to your Podfile:
pod ‘SwiftyTimer’
Install by running this command in your terminal:
pod install
Then import the library in all files where you use it:
import SwiftyTimer
Simply copy Sources/SwiftyTimer.swift
to your Xcode project.
If you like SwiftyTimer, check out SwiftyUserDefaults, which applies the same swifty approach to NSUserDefaults
.
