UItableviewCell Zelle Wiederverwendung Problem

Question

Ich zeige Bilder in scrollview horizontal in UItableviewCell.

Problem ist, wenn ich scrollen tableview Bilder bekam mismatched.Below Referenz mein Code:

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

ManufacturersTableviewCustomCell * cell = (ManufacturersTableviewCustomCell *)[tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath]; 
if (cell == nil) 
{ 
    cell = [[ManufacturersTableviewCustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; 
} 


cell.scrollview.delegate = self; 
cell.backgroundColor = [UIColor clearColor]; 
cell.backgroundView = [UIView new] ; 
cell.selectedBackgroundView = [UIView new] ; 
cell.scrollview.tag = indexPath.row; 
cell.btnViewAll.tag = indexPath.row; 

NSDictionary *dict ; 
NSArray *aryImages; 


if(isFiltered && [aryFilteredProducts count]>0){ 
    dict = [[aryFilteredProducts objectAtIndex:indexPath.row]valueForKey:@"manufacturers"]; 
    aryImages = [[aryFilteredProducts objectAtIndex:indexPath.row]valueForKey:@"sub_categories"]; 
} 
else if([aryProducts count]>0){ 
    dict = [[aryProducts objectAtIndex:indexPath.row]valueForKey:@"manufacturers"]; 
    aryImages = [[aryProducts objectAtIndex:indexPath.row]valueForKey:@"sub_categories"]; 

} 

NSString *strUppercase = [[dict valueForKey:@"manufacturers_name"] uppercaseString]; 
cell.lblManufacturerName.text = strUppercase; 

NSString *strImgUrl = [NSString stringWithFormat:@"%@/%@",KServerUrl,[dict valueForKey:@"original_image"]]; 

if(![[NSURL URLWithString: strImgUrl] isKindOfClass:[NSNull class]]) 
    [cell.imgViewManufacturer setImageWithURL:[NSURL URLWithString:strImgUrl] placeholderImage:[UIImage imageNamed:@"Background.png"] usingActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; 

[cell.viewBorder.layer setBorderColor: [[UIColor colorWithRed:234.0/255.0 green:234.0/255.0 blue:234.0/255.0 alpha:1.0] CGColor]]; 
[cell.viewBorder.layer setBorderWidth: 1.0]; 

[cell.imgViewManufacturer.layer setBorderColor: [[UIColor colorWithRed:234.0/255.0 green:234.0/255.0 blue:234.0/255.0 alpha:1.0] CGColor]]; 
[cell.imgViewManufacturer.layer setBorderWidth: 1.0]; 

CGFloat contentWidth = 0; 

for(int i=0;i< [aryImages count];i++) 
{ 
    if(SCREEN_MAX_LENGTH == 568){ 
     if([aryImages count] >3){ 
      cell.btnViewAll.hidden = NO; 
     } 
     else { 
      cell.btnViewAll.hidden = YES; 
     } 
    } 
    else{ 
     if([aryImages count] >5){ 
      cell.btnViewAll.hidden = NO; 
     } 
     else { 
      cell.btnViewAll.hidden = YES; 
     } 
    } 
    NSDictionary *dictImageData = [aryImages objectAtIndex:i]; 

    UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake([aryImages indexOfObject:dictImageData]*(80 + 5),0,80,80)]; 

    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){ 
     [imgView setFrame:CGRectMake([aryImages indexOfObject:dictImageData]*(130 + 5),0,130,130)]; 
    } 
    [imgView.layer setBorderColor: [[UIColor colorWithRed:234.0/255.0 green:234.0/255.0 blue:234.0/255.0 alpha:1.0] CGColor]]; 
    [imgView.layer setBorderWidth: 1.0]; 
    imgView.tag = i; 
    // add tapgesture 

    UITapGestureRecognizer *tapgestureImg = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(imageTapped:)]; 
    [imgView addGestureRecognizer:tapgestureImg]; 

    NSString *strImgUrlSubCat = [NSString stringWithFormat:@"%@/%@",KServerUrl,[dictImageData valueForKey:@"sub_product_img"]]; 

    imgView.userInteractionEnabled = NO; 

    imgView.image = [UIImage imageNamed:@"Background.png"]; 

    if(![[NSURL URLWithString: strImgUrlSubCat] isKindOfClass:[NSNull class]]){ 
     [imgView setImageWithURL:[NSURL URLWithString:strImgUrlSubCat ] placeholderImage:[UIImage imageNamed:@"Background.png"] usingActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; 
     imgView.userInteractionEnabled = YES; 

    } 
    [cell.scrollview addSubview:imgView]; 

    UIView *vwBackGround = [[UIView alloc]initWithFrame:CGRectMake([aryImages indexOfObject:dictImageData]*(80 + 5), 60, 80, 20)]; 
    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){ 
     [vwBackGround setFrame:CGRectMake([aryImages indexOfObject:dictImageData]*(130 + 5), 90, 130, 40)]; 
    } 
    vwBackGround.backgroundColor = [UIColor blackColor]; 
    vwBackGround.alpha = 0.5; 
    [cell.scrollview addSubview:vwBackGround]; 

    UILabel *lblProductName = [[UILabel alloc]initWithFrame:CGRectMake([aryImages indexOfObject:dictImageData]*(80 + 5)+4, 60, 70, 20)]; 
    lblProductName.font = [UIFont fontWithName:@"Helvetica" size:10.0]; 

    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){ 
     [lblProductName setFrame:CGRectMake([aryImages indexOfObject:dictImageData]*(130 + 5)+4, 90, 120, 40)]; 
     lblProductName.font = [UIFont fontWithName:@"Helvetica" size:17.0]; 

    } 
    lblProductName.textColor = [UIColor whiteColor]; 
    lblProductName.text = [dictImageData valueForKey:@"sub_product_name"]; 
    [cell.scrollview addSubview:lblProductName]; 

    [cell.scrollview bringSubviewToFront:vwBackGround]; 
    [cell.scrollview bringSubviewToFront:lblProductName]; 

    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){ 
     contentWidth += 130 + ([aryImages indexOfObject:dictImageData]==0?0:5); 
    } 
    else{ 
     contentWidth += 80 + ([aryImages indexOfObject:dictImageData]==0?0:5); 

    } 
} 


cell.scrollview.contentSize = CGSizeMake(contentWidth, cell.scrollview.frame.size.height); 

return cell; 
} 

Können Sie bitte vorschlagen, wie dieses Problem zu beheben.

Answer 1

entfernen imageviews vor dem Hinzufügen ..

löste es von unten Code in cellForRowAtIndexPath Zugabe

if ([cell.scrollview subviews]){ 
    for (UIView *subview in [cell.scrollview subviews]) { 
     if([subview isKindOfClass:[UIImageView class]] || [subview isKindOfClass:[UIView class]]){ 
     [subview removeFromSuperview]; 
     } 
    } 
}
