UIProgressView hides when scroll the tableview - iphone

Question

In my iphone app i am having a button, when I click on the button, download operation starts and i am replacing the button with UIProgressView. This UIProgressView will show the download progress. But once a UIProgressView is added, when I scroll it is disappeared. Here is my code:
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UIMenuItemCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
cell = [self getCellContentView:CellIdentifier];
cell.cellitemImage = (UIImageView *)[cell viewWithTag:2];
cell.cellItemButton = (UIButton *)[cell viewWithTag:3];
DataBaseClass *itemObj = [appDelegate.itemArray objectAtIndex:indexPath.row];
NSString *url;
if([itemObj.itemStatus isEqualToString:#"Available"]){
cell.cellItemButton.userInteractionEnabled = YES;
cell.userInteractionEnabled = YES;
[cell.cellItemButton setTitle:#"" forState:UIControlStateNormal];
[cell.cellItemButton setBackgroundImage:[UIImage imageNamed:#"img_normal"] forState:UIControlStateNormal];
[cell.cellItemButton setBackgroundImage:[UIImage imageNamed:#"img_pressed"] forState:UIControlStateHighlighted];
[cell.cellItemButton addTarget:self action:#selector(download) forControlEvents:UIControlEventTouchUpInside];
url = [NSString stringWithFormat:#"%#",itemObj.availableIcon];
}else if([itemObj.itemStatus isEqualToString:#"Downloading"]){
url = [NSString stringWithFormat:#"%#",itemObj.availableIcon];
[cell.contentView addSubview:myprogressView];
cell.cellItemButton.hidden = YES;
}
[cell.cellitemImage setImageWithURL:[NSURL URLWithString:url] placeholderImage:[UIImage imageNamed:#"item01.png"]];
cell.cellItemName.text = [NSString stringWithFormat:#"%#",itemObj.itemName];
return cell;
}
- (void)download{
UIButton *btn = (UIButton *)clickedBtnSender;
UIMenuItemCell *cell = [(UIMenuItemCell *)[[clickedBtnSender superview] superview] retain];
myprogressView = [[[CustomProgressView alloc]initWithFrame:CGRectMake(25, 140, 100, 21)] retain];
myprogressView.tag = selectedTag;
btn.hidden = YES;
for (UIProgressView *currentProgress in cell.contentView.subviews) {
if ([currentProgress isKindOfClass:[UIProgressView class]]){
[currentProgress removeFromSuperview];
}
}
[cell.contentView addSubview:myprogressView];
}
Please help.
EDIT
- (UIMenuItemCell *) getCellContentView:(NSString *)cellIdentifier {
CGRect CellFrame = CGRectMake(0, 0, 150, 60);
CGRect imgFrame = CGRectMake(20, 48, 110, 123);
CGRect btnFrame = CGRectMake(25, 140, 100, 26);
CGRect progressFrame = CGRectMake(25, 140, 100, 21);
UIImageView *itemImg;
UIButton *itemBtn;
UIProgressView *itemProgView;
UIMenuItemCell *cell = [[UIMenuItemCell alloc] init] ;
cell.frame = CellFrame;
//Initialize ImageView
itemImg = [[UIImageView alloc]initWithFrame:imgFrame];
itemImg.tag = 2;
[cell.contentView addSubview:itemImg];
//Initialize Button
itemBtn = [UIButton buttonWithType:UIButtonTypeCustom];
itemBtn.frame = btnFrame;
itemBtn.tag = 3;
itemBtn.titleLabel.textColor = [UIColor blueColor];
itemBtn.titleLabel.font = [UIFont systemFontOfSize:9.0];
[cell.contentView addSubview:itemBtn];
//Initialize ProgressView
itemProgView = [[CustomProgressView alloc]initWithFrame:progressFrame];
itemProgView.tag = 4;
//[cell.contentView addSubview:itemProgView];
return cell;
}

I think you need to have unique cellIdentifier for each cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:#"Cell%d", indexPath.row];
UIMenuItemCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [self getCellContentView:CellIdentifier];
// Some codes here
}
return cell;
}
Additional based on you last edit
Change
UIMenuItemCell *cell = [[UIMenuItemCell alloc] init];
to
UIMenuItemCell *cell = [[UIMenuItemCell alloc] initWithFrame:CellFrame reuseIdentifier:cellIdentifier];
