Answer 1

just reload table after get response.
in your case
[req2 startAsynchronous];}
-(void)requestFinished:(ASIHTTPRequest *)request
{
tableResourceArray=[request.responseString JSONValue];
[tableName reloadData]; // ** that's you need**
NSLog(#"TempArray:%d",tableResourceArray.count);
}
-(NSInteger)tableView: (UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return tableResourceArray.count;
}
