Answer 1

try this will help you.. this is the post method for updating data in WS .

NSString *post =[NSString stringWithFormat:@"uid=%@&firstname=%@&lastname=%@&phone=%@&bday=%@&about_me=%@&image=%@&image_code=%@&contact_number=%@",LoginID,fname,lname,cn,bday,abtme,strimage11,c11,cn];


NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];


NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"YOUR LINK"]];

[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

NSError *error;
NSURLResponse *response;
NSData *uData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:uData encoding:NSUTF8StringEncoding];
//    
NSMutableDictionary *temp = [data JSONValue];
//    
NSLog(@"%@",temp);

I am assuming you have your edited data, then

1. Form your json. There are several libraries out there which can help you.
2. Know the hostname of your server.
3. Know which API to hit on your server.
4. then pass this json as POST (GET is also ok, but POST is preferred).
5. Process this received json on your server.

Hope this helps. Nothing much to it actually.
