- This is a quick sample app to show how iTunesLibrary.framework works. - In order to use iTunesLibrary.framework, your application must be codesigned with a Mac developer profile from Apple. -- This is the same thing that Gatekeeper looks for. -- If you see an error involving OSStatusError 100005, it means that your app is not codesigned. -- This sample app sets CODE_SIGNING_IDENTITY to a generic "Mac Developer", but, you may wish to change this to your own identity. - When setting up a new project, you will need to set the Framework Search Path to include /Library/Frameworks. -- This is because /Library/Frameworks is a nonstandard location for a system framework, and Xcode doesn't search it by default.
