SwiftPulse

This is an iOS component for creating a single pulsing animation. It's a clone from PulsingHalo - so basically all the credits go to @shu223.

I just needed the single pulse animation (left one of the image) and decided to port it to Swift with some minor changes of the interfaces.

How to use

Add LFTPulseAnimation to your project.
Init LFTPulseAnimation (e.g. with its custom constructor) and add it to the view

pulseEffect = LFTPulseAnimation(repeatCount: Float.infinity, radius:20, position:imageView.center)
view.layer.insertSublayer(self.pulseEffect, below: imageView.layer)

Customization

##radius Use the radius property to set the max size of the pulse effect.

pulseEffect.radius = 60

##color This is is basically a subclass of CALayer so you can access the backgroundColor attribute of CALayer and set it like you are used to it.

##animation duration Use self.animationDuration to set the duration of one animation cycle. Use the self.pulseInterval property to add an interval to the duration.

##animation repeat count Initialize using LFTPulseAnimation(repeatCount: Float.infinity, radius:20, position:iv.center) to set the repeat count or use the repeatCount property

##more properties For more adjustment just look in the code, it's very easy to understand and should be seld documenting.

Issues & PRs

If someone is interested in porting the multiple pulse effect before I will do it just let me know or do a Pull Request ;)

Additional Info

I used the Async library which adds sugar for GCD in Swift. So if you wonder about the Async.background it's just a wrapped GCD call. :)
