The compiler may accept it, but it doesn't interpret it the way you think. You can confirm by checking whether your class formally conforms to the protocols. Try this with your old code and your new code, and compare: NSLog(@"conforms to protocol? %d", [ImportTool conformsToProtocol:@protocol

Re: NSTask argument list

Don't glom the arguments together.  Pass each as a separate array element: "-i", the URL string, "-c", "copy", the output string. And you don't need to quote the arguments, just pass them as is. I hope that makes sense -- I'd make it more code-like if I were at my desk rather than on my phone.

Interesting. I should mention I hadn't turned on sandboxing in this project. When I turn it on, and I set the "User Selected File" entitlement to "Read Only", I get the same behavior as before: TextEdit.app is selected in the panel's column view, and it's treated like a regular (non-bundle) di

How do I present an NSOpenPanel with a particular file pre-selected? I can pre-select a *directory* by setting openPanel.directoryURL. Since the file I want to select is actually a .app bundle, which is really a directory, you might think I'm in luck, but not quite. Here's the code I tried:
