cocoa - Locating bundles by identifier

Question

I want to create a bundle from an arbitrary bundle identifier
e.g. com.apple.iokit.IOStorageFamily

It's not an unreasonable thing to do as bundle IDs are supposed
to be unique, however the obvious code does not work:

NSString* bID = @"com.apple.iokit.IOStorageFamily";
NSBundle* bundle = [NSBundle bundleWithIdentifier:bID];

This code only works for bundles you've already loaded
(hello, chicken and egg problem), and in fact, you have
to know a little more than you'd like about the the identifier
before you can do anything. For the above style of ID
I grep out the final component and tranform it into
/System/Library/Extensions/IOStorageFamily.kext
which I then load by path.

Is this the state of the art or is there a more general way?

Answer 1

Use this

NSString *path = [[NSWorkspace sharedWorkspace] absolutePathForAppBundleWithIdentifier:@"com.apple.TextEdit"];
