# CFBundleCopyResourceURLInDirectory(_:_:_:_:) Returns the location of a resource contained in the specified bundle directory without requiring the creation of a CFBundle object. ``` func CFBundleCopyResourceURLInDirectory(_ bundleURL: CFURL!, _ resourceName: CFString!, _ resourceType: CFString!, _ subDirName: CFString!) -> CFURL! ``` ## Parameters `bundleURL` The bundle to examine. `resourceName` The name of the requested resource. `resourceType` The abstract type of the requested resource. The type is expressed as a filename extension, such as `jpg`. Pass `NULL` if you don’t need to search by type. `subDirName` The name of the subdirectory of the bundle’s resources directory to search. Pass `NULL` to search the standard CFBundle resource locations. ## Return Value A CFURL object describing the location of the requested resource, or `NULL` if the resource cannot be found. Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029). ## Discussion This function provides a means to obtain package information for a bundle without first creating a bundle. However, since CFBundle objects cache search results, it is faster to create a CFBundle object if you need to repeatedly access resources. Note that searches are case-sensitive, even on file systems (such as HFS+) that are not case sensitive with regards to file names. --- Copyright © 2026 Apple Inc.
