Drop in replacement for downloading UIImages asynchronously

Supported OS & SDK Versions

Swift 3
iOS 10 or Later
Developed in XCode 8

Installation

Drag AsynImageView.Swift to your project.

Usage

Image can be asynchronously loaded in three different ways using AsyncImageView

Usage 1

Load image from URL

let aImageView = AsyncImageView(frame: "YOUR_IMAGEVIEW_FRAME")
aImageView.imageURL = URL(string: "YOUR_IMAGE_URL")
self.view.addSubView(aImageView)

Usage 2

Load image directly from string. This is just a convinience.

let aImageView = AsyncImageView(frame: "YOUR_IMAGEVIEW_FRAME")
aImageView.imageURLString = "YOUR_IMAGE_URL_STRING"
self.view.addSubView(aImageView)

Usage 3

Load image using completion handler. This usage is helpful if you need to load images asynchronously without subclassing UIImageView from AsyncImageView. For example, UIButton's imageView can be loaded asynchronously with this usage without requiring any subclassing of AsyncImageView.

let button = UIButton(type: .custom)
button.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
button.loadImageAsync(fromURL: URL(string: "YOUR_IMAGE_URL")!, for: .normal) 
self.view.addSubview(button)

or simply

let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
imageView.loadImageAsync(fromURL: URL(string: "YOUR_IMAGE_URL")!)
self.view.addSubview(imageView)
