(You can also use the initWithPath: instance method to initialize a new bundle object.) This method takes a string parameter representing the full path to the bundle directory. To obtain the bundle at a specific path using Cocoa, call the bundleWithPath: class method of the NSBundle class. Creating a bundle by path is useful in situations where you are defining frameworks or other loadable bundles and know in advance where those bundles will be located. If you want to access a bundle other than the main bundle, you can create an appropriate bundle object if you know the path to the bundle directory. Programs launched by xinetd often experience this problem when xinetd changes the current directory to /. If neither of these is present, the bundle routines might not be able to find the main bundle directory. Bundles rely on either the path to the executable being in argv or the presence of the executable's path in the PATH environment variable. If the agent that launched the program did not specify the full path to the program's executable in the argv parameters, the main bundle value might be NULL.

The bundle code may try to create a main bundle to represent your program’s contents, but doing so is not possible in all cases. If a program is not bundled, attempting to get the main bundle might return a NULL value. When retrieving the main bundle from any application, the returned value might be NULL in the following situations: When getting the main bundle, it is still a good idea to make sure the value you get back represents a valid bundle. Listing 3-1 Getting a reference to the main bundle using Cocoa To get the main bundle in a Cocoa application, call the mainBundle class method of the NSBundle class, as shown in Listing 3-1. The main bundle is also the easiest to retrieve because it does not require you to provide any information. If you are an application developer, this is the most commonly used bundle. The main bundle is the bundle that contains the code and resources for the running application. The following sections outline the different ways you can get a reference to one of these types. Locating and Opening Bundlesīefore you can access a bundle’s resources, you must first obtain an appropriate NSBundle object or CFBundleRef opaque type. And at least in Objective-C applications, you can use whichever type suits your needs. Although these types are not directly interchangeable, they provide comparable features.

This chapter shows you how to use the NSBundle class and CFBundleRef opaque type to locate files and obtain other information about your bundle. By letting the bundle determine the location of the file, you are always assured of loading the correct file. The reason is that the path to the desired file can vary depending on the user’s native language and the bundle’s supported localizations. Instead, you use the NSBundle class or CFBundleRef opaque type to obtain the path to the file you want. When writing bundle-based code, you never use string constants to refer to the location of files in your bundle. Next Previous Accessing a Bundle’s Contents
