README.md

Hero is a library for building iOS view controller transitions. It provides a declarative layer on top of the UIKit's cumbersome transition APIs—making custom transitions an easy task for developers.

Carthage compatible Version License Xcode 9.0+ iOS 8.0+ Swift 4.0+ 中文 README Donate

      

Hero is similar to Keynote's Magic Move. It checks the heroID property on all source and destination views. Every matched view pair is then automatically transitioned from its old state to its new state.

Hero can also construct animations for unmatched views. It is easy to define these animations via the heroModifiers property. Hero will run these animations alongside the Magic Move animations. All of these animations can be interactively controlled by user gestures.

At view controller level, Hero provides several template transitions that you can set through heroModalAnimationType, heroNavigationAnimationType, and heroTabBarAnimationType. These can be used as the foundation of your custom transitions. Combine with heroID & heroModifiers to make your own unique transitions.

      

By default, Hero provides dynamic duration based on the Material Design Motion Guide. Duration is automatically determined by changes to distance and size—saving you the hassle, while providing consistent and delightful animations.

Hero doesn't make any assumptions about how the view is built or structured. It won't modify any of your views' states other than hiding them during the animation. This makes it work with Auto Layout, programmatic layout, UICollectionView (without modifying its layout object), UITableView, UINavigationController, UITabBarController, etc...

Example Gallery

Checkout the Example Gallery Blog Post for a general idea of what you can achieve with Hero

Usage Example 1

View Controller 1
redView.hero.id = "ironMan"
blackView.hero.id = "batMan"
View Controller 2
self.hero.isEnabled = true
redView.hero.id = "ironMan"
blackView.hero.id = "batMan"
whiteView.hero.modifiers = [.translate(y:100)]

Usage Example 2

View Controller 1
greyView.hero.id = "skyWalker"
View Controller 2
self.hero.isEnabled = true
greyView.hero.id = "skyWalker"

// collectionView is the parent view of all red cells
collectionView.hero.modifiers = [.cascade]
for cell in redCells {
	cell.hero.modifiers = [.fade, .scale(0.5)]
}

You can do these in the storyboard too!

Installation

CocoaPods

Add the following entry to your Podfile:

pod 'Hero'

Then run pod install.

Don't forget to import Hero in every file you'd like to use Hero.

Carthage

Add the following entry to your Cartfile:

github "HeroTransitions/Hero"

Then run carthage update.

If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained over at Carthage.

Swift Package Manager

To integrate using Apple's Swift package manager, add the following as a dependency to your Package.swift:

.package(url: "https://github.com/HeroTransitions/Hero.git", .upToNextMajor(from: "1.3.0"))

and then specify "Hero" as a dependency of the Target in which you wish to use Hero. Here's an example PackageDescription:

// swift-tools-version:4.0
import PackageDescription

let package = Package(
    name: "MyPackage",
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyPackage"]),
    ],
    dependencies: [
        .package(url: "https://github.com/HeroTransitions/Hero.git", .upToNextMajor(from: "1.3.0"))
    ],
    targets: [
        .target(
            name: "MyPackage",
            dependencies: ["Hero"])
    ]
)

Manually

  • Drag the Sources folder anywhere in your project.

FAQ

Not able to use Hero transition even when self.hero.isEnabled is set to true

Make sure that you have also enabled self.hero.isEnabled on the navigation controller if you are doing a push/pop inside the navigation controller.

Views being covered by another matched view during the transition

Matched views use global coordinate space while unmatched views use local coordinate space by default. Local coordinate spaced views might be covered by other global coordinate spaced views. To solve this, use the useGlobalCoordinateSpace modifier on the views being covered. Checkout Coordinate Space Wiki page for details.

Push animation is shown along side my custom animation

This is the default animation for navigation controller provided by Hero. To disable the push animation, set self.hero.navigationAnimationType to .fade or .none on the navigation controller.

How do I use a different default animation when dismissing

You can use the animation type .selectBy(presenting:dismissing) to specify a different default animation for dismiss.

For example:

    self.hero.modalAnimationType = .selectBy(presenting:.zoom, dismissing:.zoomOut)
