problem load tableView with data the database

[Gustavo Rocha]

I have problem in show table mode correct..





i think code correct :

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
	return 1;
}


-(NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section {    
    return[listaConta count];
}


- (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] autorelease];
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	}
	
	Conta *conta = (Conta *)[listaConta objectAtIndex:indexPath.row];
	cell.textLabel.text = [conta nomeUser];
    
    cell.textLabel.text = [[NSString alloc] initWithFormat:@"%@", nomeUser];                 
    
   // cell.text =[listaConta objectAtIndex:indexPath.row];
    
    
    
    
    return cell;
}

-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath {
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (void)tableView:(UITableView *)aTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
{
    ControlConta *controlConta = [[ControlConta alloc] init];
    
    [controlConta release];
}

I'm going to guess that nomeUser is a UITextField. UITextField's have a NSString property called "text". So instead of using initWithFormat, just assign it directly like so:

cell.textLabel.text = conta.nomeUser.text;

//Broken down
UITextField *textField = conta.nomeUser;
NSString *textInsideTextField = textField.text;
cell.textLabel.text = textInsideTextField;

this don't work...

Conta *conta = (Conta *)[listaConta objectAtIndex:indexPath.row];

    UITextField *textField = conta.nomeUser;
    NSString *textInsideTextField = textField.text; //error
    cell.textLabel.text = textInsideTextField;

Okay so it is a NSString object. Your first code should should work, try setting the detailTextLabel.text to nil.

You are probably setting the textLabel to nil. Set the detailTextLabel to nil. Like I said before though, revert back to your old code except don't create a new string object, just assign it directly with nomeUser.
