Instance Method

setBackgroundImageData(_:)

Sets the button’s background image to the image in the specified data object.

Declaration

func setBackgroundImageData(_ imageData: Data?)

Parameters

imageData

A data object containing the image data in its native format. The image is displayed behind the button’s title text. Specifying nil removes the existing image. You may specify image data that contains multiple images running as an animation. The image is scaled as needed to fill the button’s content area.

Discussion

Use this method when you already have image data in the raw PNG or JPG format. This method sends the data as-is, which lets you send the data in a compressed format. Sending compressed data is often more efficient than sending a UIImage object.
