Unsplash API client written in Swift.

Unsplash offers 2 APIs:

• Source API (unlimited requests)
• Official API
• JSON API (5000 requests / hour)

JSON API is in progress and will be available soon in this library.

Requirements

• iOS 8.0+ / Mac OS X 10.9+ / tvOS 9.0+ / watchOS 2.0+
• Xcode 8.0+

Installation

You can use CocoaPods to integrate the library with your project.

pod "UnsplashKit/API" # Official API
pod "UnsplashKit/Source" # Source API

Usage

import UnsplashKit

Official API

First thing you need is an instance of the client for executing requests and parsing responses from the API:

var token = "xxxx"
var client = UnsplashClient { request -> [String: String] in
    return [ "Authorization": "Bearer \(token)"]
}

Since the client supports providing headers for the requests, we'll use that closure to specify the authenticationt tokent that we want to pass in. UnsplashKit doesn't provide the OAuth2 authentication components, but you can use Paparajote instead.

Resources

Once the client is created you can use models' resources that contain the information about the request and about how to parse the JSON response into models whose properties you can access directly to. Here's an example:

let searchPhotos = Search.photos(query: "mountain")
client.execute(resource: searchPhotos) { (result) in
  print(result)
}

The models that contain resources are, User, Photo, Search, Collection. These resources match the endpoints available from the API. If there's any new endpoint which is not supported, you can either create an issue, open a PR or contact hello@caramba.io

Source API

Source API allows you to get an Unsplash image in different ways.

Results

All the calls return the image through a completion block that returns a Result<Image, Error>.

call() { result in
  switch result {
    case .success(let image): //handle image
    case .failure(let error): //handle error
  }
}

You can also ignore the error and get only the result using

call() { result in
  let image = result.value
}

Random photo

UnsplashSource().randomPhoto() { result in
  // handle the result
}

Random from a category

UnsplashSource().randomPhoto(fromCategory: .nature) { result in
    // handle the result
}

Unsplash offers a list of predefined categories. You can ask for a photo from any of these categories.

.buildings
.food
.nature
.people
.technology
.objects

Random from a specific user

UnsplashSource().randomPhoto(fromUser: "carambalabs") { result in
    // handle the result
}

Random from a user's likes

UnsplashSource().randomPhoto(fromUserLikes: "mkwlsn") { result in
    // handle the image
}

Random from a collection

UnsplashSource().randomPhoto(fromCollection: "176316") { result in
    // handle the result
}

Random search term

UnsplashSource().randomPhoto(fromSearch: ["nature", "water"]) { result in
    // handle the result
}

Specific photo

UnsplashSource().photo("WLUHO9A_xik") { result in
    // handle the result
}

Specific image size

If you want to get an image of a specific size you can use the optional size parameter in any call.

UnsplashSource().randomPhoto(fromCategory: .nature, size: CGSize(width: 600, height: 200)) { result in
    // handle the result
}

Fixed daily/weekly photo

The calls random, search, category and user can also be limited to only updating once per day or week. To do so, simply use the optional filter parameter.

UnsplashSource().randomPhoto(filter: .daily) { result in
    // handle the result
}
