unregister(imageWith:)
Unregisters the image with the specified trait collection from the image asset.
Declaration
func unregister(imageWith traitCollection: UITraitCollection)Parameters
- traitCollection:
A trait collection containing the traits for a previously registered image. This method matches only the trait values, so you don’t need to specify the same object you used at registration time.
Discussion
This method searches for an image whose trait collection matches the one in the traitCollection parameter. The traits in both collections must match exactly, and the matching trait collection must be associated with an image that you registered previously.
