How #import searches for files in Objective-C

Question

I can find some information on this topic. I now understand that

#import <my.h> // searches in the system paths
#import "my.h" // searches in the same dir as the source file - is that right?

I have a static library with .h files elsewhere. Can I find a compiler for a new folder for .h files C # import "my.h", as in VC ++

Answer 1

Your understanding is pretty much correct, except that it #import "my.h"searches in the same directory as the source file and all the system paths (the same as the search #import <my.h>).
