NSBundle provides methods for locating and handling application (and tool) resources at runtime. Resources includes any time of file that the application might need, such as images, nib (gorm or gmodel) files, localization files, and any other type of file that an application might need to use to function. Resources also include executable code, which can be dynamically linked into the application at runtime. These files and executable code are commonly put together into a directory called a bundle.

NSBundle knows how these bundles are organized and can search for files inside a bundle. NSBundle also handles locating the executable code, linking this in and initializing any classes that are located in the code. NSBundle also handles Frameworks, which are basically a bundle that contains a library archive. The organization of a framework is a little difference, but in most respects there is no difference between a bundle and a framework.

There is one special bundle, called the mainBundle, which is basically the application itself. The mainBundle is always loaded (of course), but you can still perform other operations on the mainBundle, such as searching for files, just as with any other bundle.

Return a bundle to access the resources for the (static or shared) library * libraryName, with interface version interfaceVersion. *

Resources for shared libraries are stored into * GNUSTEP_LIBRARY/Libraries/libraryName/Versions/interfaceVersion/Resources/; * this method will search for the first such existing directory and return it. *

*

libraryName should be the name of a library without the * lib prefix or any extensions; interfaceVersion is the * interface version of the library (eg, it's 1.13 in libgnustep-base.so.1.13; * see library.make on how to control it). *

*

This method exists to provide resource bundles for libraries and has no * particular relationship to the library code itsself. The named library * could be a dynamic library linked in to the running program, a static * library (whose code may not even exist on the host machine except where * it is linked in to the program), or even a library which is not linked * into the program at all (eg. where you want to share resources provided * for a library you do not actually use). *

*

The bundle for the library gnustep-base is a special case ... * for this bundle the -principalClass method returns [NSObject] and the * -executablePath method returns the path to the gnustep-base dynamic * library (if it can be found). As a general rule, library bundles are * not guaranteed to return values for these methods as the library may * not exist on disk. *
