Instance Property

allowsCachingHighQualityImages

A Boolean value that determines whether the image manager prepares high-quality images.

Declaration

var allowsCachingHighQualityImages: Bool { get set }

Discussion

If true (the default), the image manager prepares images at high quality. This option produces better images, at a high performance cost.

For faster performance when preparing large numbers of images—such as while the user is scrolling quickly through a collection of thumbnails—set this property to false.
