Overview

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

   ![ej1](images/ej1.gif)

* 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()

Check the sample project!

Cool ways to improve it?

Hey, If you have cool ideas to add to this please feel free to send a PR! Also if you are using this in your app and what to let me know I'll be happy to add a section here with the apps currently using this!

Can't Clear when Preparing For Reuse

I'm experiencing a bug where I have a couple timers in UITableViewCells and when scrolling sometimes the timers are set to the of another cell.

Ex: cell one: timer is at 30% ^ | | v cell two timer is supposed to be at 100% but displays at 30%

I've tried to put self.timer.animateOuterValue(0) in prepare for reuse but it didn't help

Thanks, Kevin

Animating timer with Duration does not work unless on main thread
@andresinaka When animating the timer with duration, it doesnt work unless run on the mainthread like so...perhaps this should be done in the timer object otherwise you will be left wondering why it doesnt work.

DispatchQueue.main.async { snapTimer.animateOuterToValue(100, duration: 100, completion: nil) }

Cant access Timer properties
@andresinaka The color properties are inaccessible apparently because of internal access controls.

let snapTimer = SnapTimerView(x: 0, y: 0, w: 24, h: 24) //How I initialize. Im not using storyboards
