SPPerspective

Animatable widgets from iOS 14. Same animation for transform and shadow.

Customisable duration, perspective and shadow also. For visual edit use example app, check video preview:

Ready for use on iOS 12+. Works with Swift 5+. Required Xcode 12.0 and higher.

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Once you have your Swift package set up, adding as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/ivanvorobei/SPPerspective.git", .upToNextMajor(from: "1.4.1"))
]

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate using CocoaPods, specify it in your Podfile:

pod 'SPPerspective'

If you prefer not to use any of dependency managers, you can integrate manually. Put Sources/SPPerspective folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.

For apply animation for your view, use this code:

view.applyPerspective(.iOS14WidgetAnimatable)

Use this, if need apply non-animation transform:

view.applyPerspective(.iOS14WidgetStatic)

You can customise duration, angle, shadow properties and other. All this customising by configuration file. Configuration can be animatable or static. Above you see .iOS14WidgetAnimatable & .iOS14WidgetStatic, its also configurations wich already have good-usage values same as native widgets.

For get fine configuration, better use example app (video preview). You can in real time see changes in configuration.

Next more details about customise.

When you init new animation configuration, you can set duration:

let animationConfig = SPPerspectiveAnimationConfig(duration: 16, distortion: 600, angle: 10, vectorStep: 3.14, shadow: nil)
view.applyPerspective(animationConfig)

If need change duration for default config, using this:

let animationConfig = SPPerspectiveConfig.iOS14WidgetAnimatable
animationConfig.animationDuration = 8
view.applyPerspective(animationConfig)

Angle is how much the view will rotate. For change it call angle in config:

animationConfig.angle = 10

Also you can customise distortion of perspective. Using this:

animationConfig.distortionPerspective = 600

Both properties allow you configure transform for your view. If you don't know which values shoud using, check use example app (video preview). With sliders you can customize it in detail.

Shadow also using configuration. Static and animation configs contains shadow property.

It simple. For change blur, opacity and color call this in configuration.

animationConfig.shadowConfig?.blurRadius = 5
animationConfig.shadowConfig?.opacity = 0.3
animationConfig.shadowConfig?.color = .black

Translation help customise position of shadow for any state of transform. For example you can want do more vertical translation for show deep transform.

Transform adaptive for each higlight corner. For example startVerticalOffset using when highlight top-center side. For bottom corners available cornerVerticalOffset. For bottom-center side shoud change maximumVerticalOffset . Horizontal trnalation customising by maximumHorizontalOffset.

animationConfig.shadowConfig?.startVerticalOffset = 8
animationConfig.shadowConfig?.cornerVerticalOffset = 18
animationConfig.shadowConfig?.maximumVerticalOffset = 21
animationConfig.shadowConfig?.maximumHorizontalOffset = 12

For get fine result, you shoud use this rule: startVerticalOffset < cornerVerticalOffset < maximumVerticalOffset. Visual transform available in example app (video preview), with it you get fine values.

My English is very bad. You can see this once you read the documentation. I would really like to have clean and nice documentation. If you see gramatical errors and can help fix the Readme, please contact me hello@ivanvorobei.by or make a Pull Request. Thank you in advance!

I love being helpful. Here I have provided a list of libraries that I keep up to date. For see video previews of libraries without install open opensource.ivanvorobei.by website.
I have libraries with native interface and managing permissions. Also available pack of useful extensions for boost your development process.
