My problem is this when i am reloading the tableview then the new data is rewritten on the old data that makeks content blurred and unclear and in method <code>cellForRowAtIndexPath</code> i used this code of removing label then it is also not working properly.......</p> <pre><code>NSArray *subviews = [[NSArray alloc] initWithArray:cell.contentView.subviews]; for (UILabel *subview in subviews) { [subview removeFromSuperview]; } [subviews release]; </code></pre> <p>This code is showing a row at a time otherwise no one...</p> <p>The code of <code>cellForRowAtIndexPath</code> is this....</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *identifier = @"Cell"; UITableViewCell *cell = [tableView1 dequeueReusableCellWithIdentifier:identifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease]; } cell.selectionStyle = UITableViewCellSelectionStyleNone; NSDictionary *dict = [appDelegate.webDataList objectAtIndex:indexPath.row]; tableView.backgroundColor = [UIColor colorWithRed:0.39 green:0.39 blue:0.39 alpha:0.39]; if([appDelegate.dataArray count]&gt;0){ imgView.backgroundColor = [UIColor clearColor]; imgView =[[UIView alloc ] initWithFrame:CGRectMake(0,0,320,45)]; imgView.tag= indexPath.row+250; [cell.contentView addSubview:imgView]; button=[UIButton buttonWithType:UIButtonTypeCustom]; button.frame=CGRectMake(291, 5, 19, 21); img =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"swap_re" ofType:@"png"]]; [button setBackgroundImage:img forState:UIControlStateNormal]; [button addTarget:self action:@selector(swapButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; button.tag= indexPath.row+250; [imgView addSubview:button]; button=[UIButton buttonWithType:UIButtonTypeCustom]; button.frame=CGRectMake(-25, 5, 19, 21); img =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"swap_re" ofType:@"png"]]; [button setBackgroundImage:img forState:UIControlStateNormal]; [button addTarget:self action:@selector(swapButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; button.tag= indexPath.row+250; [imgView addSubview:button]; button=[UIButton buttonWithType:UIButtonTypeCustom]; button.frame=CGRectMake(5, 7, 19, 21); button.tag = indexPath.row+250; img =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"delete" ofType:@"png"]]; [button setBackgroundImage:img forState:UIControlStateNormal]; [button addTarget:self action:@selector(deleteButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; [imgView addSubview:button]; NSArray *arr = [[appDelegate.dataArray objectAtIndex:indexPath.row] componentsSeparatedByString:@"/"]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(34,9,140,20)]; label.text = [arr objectAtIndex:1]; label.tag = indexPath.row+250; [label setFont:[UIFont fontWithName:@"Georgia" size:14]]; [label setNumberOfLines:0]; label.textAlignment = UITextAlignmentLeft; label.textColor = [UIColor whiteColor]; label.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight; label.backgroundColor = [UIColor clearColor]; [imgView addSubview:label]; [label release]; NSDictionary *dict1 =[appDelegate.webDataList objectAtIndex:indexPath.row]; label = [[UILabel alloc] initWithFrame:CGRectMake(181, 7, 75, 20)]; label.tag = indexPath.row+250; label.text = [dict1 objectForKey:@"time"]; [label setFont:[UIFont fontWithName:@"Georgia" size:16.0]]; label.textAlignment = UITextAlignmentLeft; [label setBackgroundColor:[UIColor clearColor]]; label.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight; [label setTextColor:[UIColor whiteColor]]; [imgView addSubview:label]; [label release]; } return cell; } </code></pre> <p>and in my code i am not able to use the method <code>reuseTableViewCellWithIdentifier:</code> because i want each label and button tag should be same because i have to fetch them else where.</p>
