imgix-objc has been deprecated in favor of imgix-swift. Don't worry though, Objective-C users! imgix-swift works great with Swift and Objective-C codebases! Make sure to check it out.
Official imgix client for iOS and macOS.
Written in Objective-C for maximum flexiblity. It's annotated with nullability so it works well with Swift.
All of the options are implemented as properties with inline documentation so it's easy to manipulate your images without looking up their documentation. Simply create an IGXClient with your host and token. (You can specify nil for your token if you don't want signed URLs.)
Once you have a client, you can call URLWithPath: to generate an imgix URL for a given path. To generate URLs with parameters, just call URLWithPath:andOptions: with an NSDictionary of options instead.
The following example is in Swift, but you can of course use this library in Objective-C as well.
import Imgix
// Create a client
let client = IGXClient(host: "nothingmagical.imgix.net", token: "sMTidnYXXg9NB4qh")
// Generate a signed URL
client.URLWithPath("sam.jpg")
// => https://nothingmagical.imgix.net/sam.jpg?s=...
// Generate another signed URL, with adjusted brightness
client.URLWithPath("sam.jpg", options: ["bri": 10])
// => https://nothingmagical.imgix.net/sam.jpg?bri=10&s=...
