Objective C Cell Accessory view

Question

When I try to set the accessory view of a table view cell to a custom type image and run it in the simulator, I see that multiple cells have the accessory view image instead of the one that is currently selected. But when I set the accessory view to "cell.accessoryType = UITableViewCellAccessoryCheckmark;", I don't have this problem. Here is the code.

id item = [_items objectAtIndex:row];

if ([_currentVale isKindOfClass:[NSString class]])
{
    if ([item isEqualToString:_currentVale])
    {

        UIImageView *checkmark = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checkmark-outline.png"]];
        checkmark.frame = CGRectMake(0, 0, 20, 20);
        cell.accessoryView = checkmark;
    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
}
else if ([_currentVale isKindOfClass:[NSNumber class]])
{
    if ([item isEqualToNumber:_currentVale])
    {
        cell.accessoryType = UITableViewCellAccessoryNone;

    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;


    }
}

Two images of what I'm talking about. Only one value should be chosen in the picker but there is two showing the checkmark

细胞正在重复使用。您还需要在其他内部将附件视图设置为nil。

在单元格中，您不想显示图像，不要忘记设置

func deleteThisFile(fileToDelete: String) {
    let tempLocalDir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first
    do {
        let directoryContents = try FileManager.default.contentsOfDirectory(at: tempLocalDir!, includingPropertiesForKeys: nil, options: [])
        let tempList = directoryContents.filter{ $0.absoluteString.contains(fileToDelete) }

        //tried these things:
        try FileManager.removeItem(tempList.first) // Argument labels '(_:)' do not match any available overloads
       /*
        * try FileManager.removeItem(at: tempList.first!) // Ambiguous reference to member 'removeItem(atPath:)'
        * 
        * try FileManager.removeItem(atPath: (tempList.first?.absoluteString)!) // Ambiguous reference to member 'removeItem(atPath:)'
        */ 

    } catch let error as NSError {
        print(error.localizedDescription)
    }
}
