Cache difference between uimage and constructor Methods

When creating a uiimage object, you can use the class-level constructor + imagenamed: And the instance constructor-initwithcontentsoffile :.

+ Imagenamed: The method creates a cache in the memory. These caches are not cleared until the application is stopped. For images (logos, logos, etc.) that run through the entire application, + imagenamed is recommended for creation. If only one image is used, the following statement is recommended:

Nsstring * Path = [[nsbundle mainbundle] pathforresource: @ "Animal-2" oftype: @ "PNG"]; uiimage * image = [[uiimage alloc] initwithcontentsoffile: path]; ...... [Image release]; // called under MRC
