                    imagePlaceholder

The image placeholder

By default, this returns an image named “img_placeholder” from the CheetahLoyaltyUI Assets.

Declaration

Swift

static var imagePlaceholder: UIImage? { get }


                    
                    
                    loadImage(for:with:completion:)

Default implementation

Load an image for the given image view with the given url string.

The default implementation of this method tries to create a URL from the given url string and then calls loadImage(for: UIImageView, with: URL). If the given url string is not a valid url, this will do nothing and not also execute the completion closure.

Default Implementation

Undocumented
