ios - Data repeat in UITableView when scrolling

Question

I use bellow codes to show data on TableView but when scrolling, data repeat and other data lost.

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

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

}

cellForRowatindexpath ():

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"CellIdentifier";

    UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

        UILabel *FileNameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 100, 30)];
        FileNameLabel.backgroundColor = [UIColor clearColor];
        FileNameLabel.font = [UIFont fontWithName:@"Helvetica" size:16];
        FileNameLabel.font = [UIFont boldSystemFontOfSize:16];
        FileNameLabel.textColor = [UIColor blackColor];
        NSLog(@"Reseversed TEMP array %@",FileCompletedArray);
        FileNameLabel.text =[FileCompletedArray objectAtIndex:indexPath.row];
        [cell.contentView addSubview: FileNameLabel];
        [FileNameLabel release];



    }
        return cell;
}

Do you have any solutions? Thanks in advance

Answer 1

use cell Identifier different

For example like bellow...

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    NSString *CellIdentifier = [NSString stringWithFormat:@"%d,%d",indexPath.section,indexPath.row];

    UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        /// write your code here..
    }
}

OR set nil like bellow..

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    //static NSString *CellIdentifier = @"CellIdentifier";    

    UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:nil];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];
        /// write your code here..
    }
}
