Question

i am new to iOS Development so please go easy on me.

I have an existing ecommerce site set up using oscommerce that requires a user to log in to view products, i want to build an app that will access this store.

That being said i have been able to successfully connect to the store using the ASIHTTPRequest Library. The only thing i am unsure of is how to get the information back so that i can build my application. i have heard people saying XML, and JSON but i guess i am still not sure how i can get the data on my site into my app. like getting categories into a uitableview for example.

Does anyone have any examples or links to where i might start.

Answer 1

In this function you will get the response of server i:e the ResponseData returned by server,
all you need is to parse this data and save it locally for further use.
For parsing you can there are options to use NSXMLParser, TouchXMLParser, JSON
parsing. Its on you what to use.

- (NSData*)sendRequest
{
   ASIHTTPRequest *getRequest = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:@"http://myurl.com"]];
 NSData *responseData = nil;
    [getRequest start];


    //if we have encounter any error
    NSError *error = [getRequest error];

    if (!error) 
    {
        responseData = [getRequest responseData];

    }

     return responseData;
}
