How to get the executable path of a command line tool in Objective C (Foundation framework)?

Question

Hi, I'm trying to work out a way to identify the executable path of a command line tool in Objective C.

Hence, if the executable is /Applications/Utils/MyTool, then that method would return /Applications/Utils

I'm using the Foundation framework.

Any help would be great, thanks

Answer 1

You probably want NSString's stringByDeletingLastPathComponent.

Answer 2

I'm assuming that by /Applications/Utils/MyTool, you mean an application named "MyTool" in the "Utils" directory within the "Application" directory (which is actually the path /Applications/Utils/MyTools.app). In that case, you could get the directory in which the application resides (/Applications/Utils) with the following bit of code:

NSString *appParentDirectory = [[[NSBundle mainBundle] bundlePath] stringByDeletingLastPathComponent];
