Display Image on a button from a URL in swift

Question

I need to display the background image of a button by giving the image source from an external URL instead of downloading the image. Is there a possible way to do this in swift.

Answer 1

You can use SDWebImage POD.

yourBtn.sd_setImage(with: <#T##URL?#>, for: <#T##UIControl.State#>, completed: <#T##SDExternalCompletionBlock?##SDExternalCompletionBlock?##(UIImage?, Error?, SDImageCacheType, URL?) -> Void#>)

Answer 2

First you need to get the image data from external URL and then use the image

if let url = URL(string: "YOUR-IMAGE-URL-HERE") {
            do{
                let data = try Data(contentsOf: url)
                self.imageVar = UIImage(data: data)
                if let myImage: UIImage = self.imageVar {
                    YOUR-BUTTON-NAME.setImage(myImage, for: .normal)
                }
            }catch {
                print("error")
            }
        }
