To integrate JSON framework in IOS applications use following steps.
  • Have a look at the features Introductions at google’s home page
  • Download and extract the source from GitHub
  • Rename directory named Classes to JSON.
  • This step will involve some small individual steps
    • Move the renamed directory to Classes directory of target project
    • Open target project choose Classes group
    • Now right click and choose Add -> Existing files and add JSON to it.
  • Usage
    • Import json.h in the class you wish to use json.
    • For ObjC to JSON you can call JSONRepresentaion on any object
      NSArray *arr=[NSArray arrayWithObjects:@"1",@"2",@"3",nil];
      NSLog(@"%@",[arr JSONRepresentation]);
      logs [“1″,”2″,”3”];
    • For JSON to ObjC you need to parse the string to convert JSON to an ObjC object.
      SBJsonParser *parser=[[SBJsonParser alloc] init];
          NSArray *arr2=[parser

And that’s it,you are done with JSON Integration.
