Set path to .dylib path in Cocoa app

I'm developing a Mac OS X Cocoa app and want to use several .dylib libraries. How do I set the path to a .dylib which re开发者_运维技巧sides somewhere in my Application folder? What if the path resides in different directories on different computers or is not existent at all?

Use @rpath. (or @executable_path.) See man 1 dyld.

What if the path resides in different directories on different computers or is not existent at all?

Then your app will fail to load. Use weak linking or load the dylib at runtime with dlopen if the dylib is not essential.
