minimumValueImage
The image that represents the slider’s minimum value.
Declaration
var minimumValueImage: UIImage? { get set }Discussion
The image you specify must fit within the bounding rectangle returned by the minimumValueImageRect(forBounds:) method. If it doesn’t, the slider scales the image to fit. In addition, the slider lengthens or shortens its track as needed to accommodate the image in its bounding rectangle.
Because minimum is a semantic concept, in a right-to-left user interface, the slider automatically flips the image placement, always placing it at the leading end of the slider’s track.
The default value of this property is nil.
