SnapTimer

SnapTimer is a custom UIView that behaves exactly the same as the one on Snapchat's stories.

Swift 3.0 Support on master branch! 👌👌 
Swift 2.3 Support on Swift2.3.

Features

• Two different timers, 'outer' and 'inner'.
• Independent animations for each of the timers.
• Customizable colors.
• Completion handlers.
• Fully Swift.

What does it look like?

A picture is worth a thousand words

Installation

You can just clone the repo and copy the SnapTimer folder to your project or you can use one of the following options:

Setting up with CocoaPods

pod 'SnapTimer'

Then:

import SnapTimer

And you are all set!

Setting up with Carthage

• TODO

How do I add it?

• Add a UIView to your Storyboard.

• Select the view, go to the Identity Inspector and set the class to SnapTimerView

  

• Create an @IBOutlet in your view controller and that's it.

  SnapTimerView implements @IBDesignable so the view should automatically render in your Interface Builder. Also it implements @IBInspectable for the view properties:

  

• That's it!

Setting inner and outer values

innerValue and outerValue ranges go from 0 to 100.

• To set values without animations you just have to:

self.snapTimerView.outerValue = 25 self.snapTimerView.innerValue = 50

* To animate values:

    ```swift
self.snapTimerView.animateOuterValue(50)
self.snapTimerView.animateInnerValue(25)

• To animate values setting the time and a completion handler:

  self.snapTimerView.animateOuterToValue(50, duration: 30) {
      puts("Done!")
  }
  
  self.snapTimerView.animateInnerToValue(100, duration: 30) {
      puts("Done!")
  }
  

Pausing and resuming animations:

if your app goes to background or the Notifications/Control center are opened you may want to pause the animations, to do that SnapTimer has two handy methods:

self.snapTimerView.resumeAnimation()
self.snapTimerView.pauseAnimation()
