How to define the API Url's in Objective-C

Question

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?

Answer 1

bari or ;),
You can define like this

#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)       [NSString stringWithFormat:@"%@/%@/like", POSTS, id]

And use it

NSString *someId = @"5";
kAPI_ADD_LIKE_URL(someId);

try this.

#define kAPI_ADD_LIKE_URL(id)       [NSString stringWithFormat:@"%@/%d/lik",POSTS,id]

#define BASE_URL                    @"http://www.........."
#define POST                        [NSString stringWithFormat:@"%@/user_posts",BASE_URL]
#define kAPI_GET_POSTS_LIST_URL     POSTS
#define kAPI_ADD_LIKE_URL(uri)      [NSString stringWithFormat:@"%@/%@/like",POSTS,uri]

Hope this will help :)
