Can someone show how can I parse it? The text that i need to parse is in body variable

NSMutableString *body = [[NSMutableString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

I need to insert all info in one Array or in a NSDictionary

Best to use an objective-c parsing library.

This article has a good run down of some of the available ones:

Also, this page has full code samples using one of the libraries:
