How to use dylib file in application?

Question

I have created lib.dylib dynamic library. I want to use that library in my application. What are the Build setting and build phase settings are required? Steps to use the library in objective-c.

Answer 1

so there are 2 ways...

1) if the Dyld is available at link time, then you just link against it. (in Xcode you add it to the link build phase of the target you are building.)

if using a framework: The headers will end up in the header search path so you can #import <framework/header.h> them.

2) if it isn't then you will need to open the dynamic library with dlopen, then you read in each function directly... this is much more of a specialty task, like dealing with a plug-in architecture.

there are some tricky thinks if you are supplying the dynamic lib then there are issues with the library install path being relative to the executable... but you will just have to tackle them if you hit them (start by googling @rpath)
