Question

嗨朋友我在桌子上显示图像表示表格有10个单元格

但我只在两个单元格上显示图像

当我滚动表视图时，这个图像逐个显示在所有单元格上

所以我在这里做错了什么。

static NSString * identifier = @“CellTypeLabel”;

    // create custom cell
CustomizedTableCells* cell = nil;   
if (cell == nil)
    cell = [[[CustomizedTableCells alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease];

    // cell accessory type
cell.accessoryType =  UITableViewCellAccessoryDisclosureIndicator;

cell.imageView.image = nil;

NyhtrAppDelegate *appDelegate = (NyhtrAppDelegate *)[[UIApplication sharedApplication] delegate];
NSXMLElement* node = [appDelegate.items objectAtIndex:indexPath.row];
NSLog(@"\n Output :: %@ :: ", [node XMLString]);

    // set the lable name for a cell
if(node != NULL)
{       
    int width = cell.contentView.bounds.size.width-50;
    if([[[node elementForName:@"pubDate"] stringValue]length] > 0)
        [cell setCellWithTitleAndSize:[[node elementForName:@"title"] stringValue] rect:CGRectMake(45, 0, width, 35) size: 17];
    else
        [cell setCellWithTitleAndSize:@"N/A" rect:CGRectMake(45, 0, width, 35) size: 17];       
}   

NSXMLElement* iconElement = [self getIconElementForThisDomain:[self getDomain:node]];

NSString* iconImageUrl = nil;
if (nil != iconElement)
    iconImageUrl = [[iconElement elementForName:@"retina-icon"]stringValue];
else
    iconImageUrl = @"http://nyhtr.se/icon/nyheter24.png";   

// cached images    
NSString* imageName = [[UICachedImageMgr defaultMgr] imageNameFromURLString:iconImageUrl];
UIImageProxy* imageProxy = [UICachedImageMgr imageWithName:imageName userInfo:self];

cell.imageView.image = imageProxy.image;     

return cell;

Answer 1

检查以下方法并仅将图像添加到匹配的indexpath.row整数值

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    //check the indexPath
    if(indexPath.row==0 || indexPath.row==5){
    }
    else{
    //other stuff
    } 

}

如果您使用单元格出列，则您出列的单元格可能是包含图像的单元格之一。

因此，如果您的单元格已经出列，则必须检查图像是否存在并将其删除。

UIITabelViewCell显示不正确的图像
