README
THIS PROJECT IS NO LONGER MAINTAINED.
Popsicle is a Swift framework for creating and managing interpolations of different value types with built-in UIKit support.
Installation
Carthage
github "DavdRoman/Popsicle"
CocoaPods
pod 'Popsicle'
Manual
Drag and copy all files in the [Popsicle](Popsicle) folder into your project.
At a glance
Interpolating UIView (or any other NSObject) values
First, you need an Interpolator
instance:
let interpolator = Interpolator()
Next, you need to add some Interpolation<T>
instances to your interpolator. In the example below, we are going to interpolate the alpha value of a UIView for times between 0 and 150:
let interpolation = Interpolation(yourView, alpha)
interpolation[0] = 0
interpolation[150] = 1
self.interpolator.addInterpolation(interpolation)
Note alpha
is a built-in KeyPath<T, U>
constant. Popsicle offers a nice set of [UIKit-related KeyPaths](Popsicle/KeyPath.swift) ready to be used. You may also use a completely custom key path.
You can also modify the easing function used at a given time:
interpolation.setEasingFunction(EasingFunctionEaseOutQuad, forTime: 0)
There's a bunch of [built-in easing functions](Popsicle/EasingFunction.swift) to choose from.
Finally, just make your interpolator
vary its time
depending on whatever you want. For example, the content offset of a UITableView
:
func scrollViewDidScroll(scrollView: UIScrollView) {
interpolator.time = Double(scrollView.contentOffset.y)
}
Interpolating custom values
You can declare a value type as interpolable by making it conform to the Interpolable
protocol.
As an example, check out how CGPoint
conforms to Interpolable
:
extension CGSize: Interpolable {
public static func interpolate(from fromValue: CGSize, to toValue: CGSize, withProgress progress: Progress) -> CGSize {
let width = CGFloat.interpolate(from: fromValue.width, to: toValue.width, withProgress: progress)
let height = CGFloat.interpolate(from: fromValue.height, to: toValue.height, withProgress: progress)
return CGSizeMake(width, height)
}
public static func objectify(value: CGSize) -> AnyObject {
return NSValue(CGSize: value)
}
}
