Question

Am I the only one who get this problem?

I have few sections and few rows in grouped table view, for registration page. When I slide up and down the page, there’s strange separator bold line appear between two cells. Some of the cell sinks like it has been pressed. Is this a iOS 5.0 bug? I have worked for 3 days for this little problem. Please help!

I have try

self.tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;


and

self.tableView.separatorColor = [UIColor lightGrayColor];

None of them work.

Paul Peelen you’re right and I know what you meant, but I don’t have the knowledge to continue forward. Before I comment the “if(cell == nil)”, everything is the same as what you’ve said. But after I comment it, the label is displayed well and no problem with the separator line anymore, but when I insert the texts into the textField and slide down, and up again, the textField’s text is gone and been refreshed. How do I solve this one?
Below is my code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 
static NSString *CellIdentifier = @"LabelCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

//Here's the problem!
if(cell == nil)
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

cell.selectionStyle = UITableViewCellSelectionStyleNone;

UILabel *keyLbl = [[UILabel alloc] initWithFrame:CGRectMake(15, 8, 100, 30)];
keyLbl.font = [UIFont fontWithName:@"Futura-CondensedExtraBold" size:15.0];
keyLbl.textColor = [UIColor colorWithRed:0.275 green:0.275 blue:0.275 alpha:0.9];
keyLbl.backgroundColor = [UIColor clearColor];


valTxtField = [[UITextField alloc] initWithFrame:CGRectMake(120, 5, 180, 30)];
valTxtField.font = [UIFont fontWithName:@"Futura-CondensedExtraBold" size:18.0];
valTxtField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
valTxtField.delegate = self;
valTxtField.returnKeyType = UIReturnKeyDone;
valTxtField.autocorrectionType = UITextAutocorrectionTypeNo;
valTxtField.autocapitalizationType = UITextAutocapitalizationTypeNone;

if(indexPath.section == 0)
{
    if(indexPath.row == 0)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_EMAIL", nil);
        email_TextField = valTxtField;
    }
    else if(indexPath.row == 1)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_RE_EMAIL", nil);
        reEmail_TextField = valTxtField;  
    }
    else if(indexPath.row == 2)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_PWD", nil);
        password_TextField = valTxtField;
        valTxtField.secureTextEntry = YES;
    } 
    else if(indexPath.row == 3)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_RE_PWD", nil);
        rePassword_TextField = valTxtField;
        valTxtField.secureTextEntry = YES;
    }

}
else if(indexPath.section == 1)
{
    if(indexPath.row == 0)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_FIRSTNAME", nil);
        firstName_TextField = valTxtField;
    }
    if(indexPath.row == 1)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_LASTNAME", nil);
        lastName_TextField = valTxtField;
    }
    if(indexPath.row == 2)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_POSTCODE", nil);
        postCode_TextField = valTxtField;
    }
    if(indexPath.row == 3)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_GENDER", nil);
        gender_TextField = valTxtField;
    }
    if(indexPath.row == 4)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_DOB", nil);
        DOB_TextField = valTxtField;
    }
    if(indexPath.row == 5)
    {
        keyLbl.text = NSLocalizedString(@"REGIS_MOBILE", nil);
        mobile_TextField = valTxtField;
    }
}
[cell addSubview:keyLbl];
[cell addSubview:valTxtField];
[keyLbl release];
[valTxtField release];

return cell;

}

OK, this is mainly because the cell identifier. Since the table view recycle its contents to display every time I scroll up and down, and if I use the same cell identifier, strange behaviour like I mentioned above will happen.

This is my solution to all the strange things happen on displaying the table view:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//Here the solution:
NSString *CellIdentifier = [NSString stringWithFormat:@"RCell%1dR%1d",indexPath.section,indexPath.row];

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) 
{
   //your tableView code...
}
