U have done web services perfectly, now wat u have to do is parse it to an array
First download the SBJSON files in this link
https://github.com/stig/json-framework/
Then, copy them to your workspace. Then, in the viewController add this
#import "SBJson.h"
Your JSON data contains values in the form of dictionary
SO, to parse them
SBJsonParser * parser=[SBJsonParser new];
NSDictionary * jsonData=(NSDictionary *)[parser objectWithString:outputData];
NSArray * arr=(NSArray *)[NSDictionary objectForKey:@"animal"];
I think this will help
