Question

我的应用中包含tableview的视图。我使用 cellForRowAtIndexPath 函数填充tableview，但有时会崩溃并抛出如下错误。它很少发生，但我想解决它！

代码部分：

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

    if (self.productViewType == ProductToShelfViewTypeShelf) {

        static NSString* cellIdentifier = @"ShelfCell";
        ShelfCellView* cell = (ShelfCellView*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
        if (cell == nil) {
            NSArray* nibObjects = [[NSBundle mainBundle] loadNibNamed:@"ShelfCellView" owner:nil options:nil];
            for (id currentObject in nibObjects) {
                if ([currentObject isKindOfClass:[ShelfCellView class]]) {
                    cell = (ShelfCellView*)currentObject;
                }
            }
            [cell initViewStyles];
        }

        Shelf* shelf = [self.shelfList objectAtIndex:indexPath.row];
        cell.shelf = shelf;
        [cell initView];
        return cell;
    }
    else {
        static NSString* cellIdentifier = @"ProductToShelfCell";
        ProductToShelfCellView* cell = (ProductToShelfCellView*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
        if (cell == nil) {
            NSArray* nibObjects = [[NSBundle mainBundle] loadNibNamed:@"ProductToShelfCellView" owner:nil options:nil];
            for (id currentObject in nibObjects) {
                if ([currentObject isKindOfClass:[ProductToShelfCellView class]]) {
                    cell = (ProductToShelfCellView*)currentObject;
                }
            }
            [cell initViewStyles];
        }
        Product* product = [self.products objectAtIndex:indexPath.row];
        cell.product = product;
        [cell initView];
        return cell;
    }

    return nil;
}

在.m文件中添加以下代码，对我有用

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    NSBundle *bundel = [NSBundle bundleForClass:[Yourclassname class]];

    self = [super initWithNibName:nibNameOrNil bundle:bundel];
    if (self) {

        // Custom initialization
    }
    return self;
}

无法在捆绑中加载NIB：＆＃39; NSBundle＆＃39;在ios？
