I want to define the API URL's in a single header file, like
#define BASE_URL                    @"http://xxx.xxx.xxx.xxx/api"
#define POSTS                       BASE_URL @"/user_posts"
#define kAPI_GET_POSTS_LIST_URL     POSTS
#define kAPI_ADD_LIKE_URL(id)       POSTS @"/" id @"/like"
......
But it does not work when the 'id' is dynamic. Is there any better ways to organize API Url's?
                        
bari or ;),
