The name of the image asset or file. For images in asset catalogs, specify the name of the image asset. For PNG images, you may omit the filename extension. For all other file formats, always include the filename extension.
The bundle containing the image file or asset catalog. Specify
nilto search the app’s main bundle.
The image configuration that you want. Use this parameter to specify traits and other details that define which variant of the image you want. For example, when requesting a custom symbol image, you can specify whether you want the thin, regular, or bold image variant.
An object containing the image variant that matches the specified configuration data, or
nil if no suitable image was found.
When searching the asset catalog, this method checks first for an asset containing a symbol image, and then for an asset containing a bitmap image. Because symbol images are supported only in iOS 13 and later, you may include both types of assets in the same asset catalog. The system automatically falls back to the bitmap image on earlier versions of iOS. You cannot use this method to load system symbol images; use the
system method instead.
This method checks the system caches for an image with the specified name and returns the variant of that image that is best suited for the specified configuration. If a matching image object is not already in the cache, this method creates the image from an available asset catalog or loads it from disk. The system may purge cached image data at any time to free up memory. Purging occurs only for images that are in the cache but are not currently being used.
