⚠️ UnsplashPhotoPicker is not compatible with Objective-C.

Installation

Swift Package Manager

To integrate UnsplashPhotoPicker into your Xcode project using Switf Package Manager, open dependency manager through File > Swift Packages > Add Package Dependency....

and insert repository URL:

https://github.com/unsplash/unsplash-photopicker-ios.git

To add dependency in your own package, just specify it in dependencies of your Package.swift:

.package(
  name: "UnsplashPhotoPicker",
  url: "https://github.com/unsplash/unsplash-photopicker-ios.git",
  .upToNextMajor(from: "1.2.0")
)

Carthage

To integrate UnsplashPhotoPicker into your Xcode project using Carthage, specify it in your Cartfile:

github "unsplash/unsplash-photopicker-ios" ~> 1.2

Run carthage update to build the framework and drag the built UnsplashPhotoPicker.framework into your Xcode project.

CocoaPods

To integrate UnsplashPhotoPicker into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '12.1'
use_frameworks!

target '<Your Target Name>' do
    pod 'UnsplashPhotoPicker', '~> 1.2'
end

Then run pod install.

Git submodule

If you prefer not to use any of the aforementioned dependency managers, you can integrate UnsplashPhotoPicker into your project manually as a git submodule by running the following command in the project's folder:

$ git submodule add https://github.com/unsplash/unsplash-photopicker-ios.git

Drag the UnsplashPhotoPicker.xcodeproj file into your Xcode project, then drag the UnsplashPhotoPicker.framework to your target's "Embedded Binaries".

Usage

❗️Before you get started, you need to register as a developer on our Developer portal. Once registered, create a new app to get an Access Key and a Secret Key.

Configuration

The UnsplashPhotoPicker is configured with an instance of UnsplashPhotoPickerConfiguration:

UnsplashPhotoPickerConfiguration(accessKey: String,
                                 secretKey: String,
                                 query: String,
                                 allowsMultipleSelection: Bool,
                                 memoryCapacity: Int,
                                 diskCapacity: Int)

Property	Type	Optional/Required	Default
accessKey	String	Required	N/A
secretKey	String	Required	N/A
query	String	Optional	nil
allowsMultipleSelection	Bool	Optional	false
memoryCapacity	Int	Optional	50
diskCapacity	Int	Optional	100

Presenting

UnsplashPhotoPicker is a subclass of UINavigationController. We recommend that you present it modally or as a popover on iPad. Before presenting it, you need to implement the UnsplashPhotoPickerDelegate protocol, and use the photoPickerDelegate property to get the results.

protocol UnsplashPhotoPickerDelegate: class {
  func unsplashPhotoPicker(_ photoPicker: UnsplashPhotoPicker, didSelectPhotos photos: [UnsplashPhoto])
  func unsplashPhotoPickerDidCancel(_ photoPicker: UnsplashPhotoPicker)
}

Using the results

UnsplashPhotoPicker returns an array of UnsplashPhoto objects. See UnsplashPhoto.swift for more details.
