json ios5 nothing at the screen - json

Question

i have just install the xcode 4.2.1 with ios5 and i try to use json.
this my code
-(void)start
{
responseData = [[NSMutableData data]retain];
membreArray = [NSMutableArray array];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http:******.php"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[responseData setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[responseData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(#"error %#",error);
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
[responseData release];
jsonArray = [responseString JSONValue];
NSLog(#"array %#",jsonArray);
}
in my NSLog(#"array %#",jsonArray); i can see all records,everything is ok. But in my tableview nothing at the screen.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [jsonArray count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
// Configure the cell.
NSDictionary *dico = [self.jsonArray objectAtIndex:indexPath.row];
cell.textLabel.text = [dico objectForKey:#"name"];
return cell;
}
this code work on xcode 3 but not in xcode 4.
somes helps please.

After you finish loading the data, you need to tell your tableview to reload. I'm not seeing that in your code. Try something like this:
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
[responseData release];
jsonArray = [responseString JSONValue];
NSLog(#"array %#",jsonArray);
/* This tells your tableView to reload */
[tableView reloadData];
}
Also, make sure your TableView is connected in the designer via an IBOutlet. Otherwise your reloadData command will fall on deaf ears.
