How to organize an API URL in Objective-C

Question

I am trying to organize my entire API url in a single file, what I do, I created a header file and added the following lines

#define LOGIN_URL @"http://192.168.100.100/api/login" #define SIGNUP_URL @"http://192.168.100.100/api/signup" #define PRODUCTS_URL @"http://192.168.100.100/api/products" #define EMPLOYEE_URL @"http://192.168.100.100/api/employee" #define GET_PRODUCTS_URL @"http://192.168.100.100/api/getproducts" #define CLIENTS_URL @"http://192.168.100.100/api/clients" 

Here the base url is http://192.168.100.100/ , which will change, I always need to find and replace the IP address. Are there any more efficient ways to organize an Url API?

Hey, you can organize your entire API URL using the following code

 #define SITE_URL(url) @"http://192.168.100.100/api" url #define LOGIN_URL SITE_URL("/login") #define SIGNUP_URL SITE_URL("/signup") #define PRODUCTS_URL SITE_URL("/products") #define EMPLOYEE_URL SITE_URL("/employee") #define GET_PRODUCTS_URL SITE_URL("/getproducts") #define CLIENTS_URL SITE_URL("/clients")

I personally like to use constants over #define

This is how I will do what you are trying to do.

MyAppConstants.h

 extern NSString * const kLOGIN_URL; extern NSString * const kSIGNUP_URL; extern NSString * const kPRODUCTS_URL; extern NSString * const kEMPLOYEE_URL; extern NSString * const kGET_PRODUCTS_URL; extern NSString * const kCLIENTS_URL; 

MyAppConstants.m

 NSString * const kLOGIN_URL = @"/login" NSString * const kSIGNUP_URL = @"/signup" NSString * const kPRODUCTS_URL = @"/products" NSString * const kEMPLOYEE_URL = @"/employee" NSString * const kGET_PRODUCTS_URL = @"/getproducts" NSString * const kCLIENTS_URL = @"/clients" 

Then when I use constants, I would do something like ...

 NSURL *loginURL = [NSURL URLWithString:[baseUrl stringByAppendingString:kLOGIN_URL]];
