Question

我在storyboard中使用正确的重用ID创建了两个原型。调试器在我的自定义单元格内的各个断点处停止，但表视图仍然显示空白单元格。是什么给了什么？

提前致谢

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

static NSString *CellID = @"CellIdentifier";
static NSString *CommentCellID = @"CommentCellIdentifier";

// for iOS6+ not specifying forIndexPath:indexPath causes assertion when endUpdates is called

NSUInteger sectionNumber = [indexPath section];
switch (sectionNumber) {
    case 2: {

        // Try to dequeue a cell and create one if necessary
        SDCCommentCell *commentCell = [tableView dequeueReusableCellWithIdentifier:CommentCellID];
        if (commentCell == nil) {
            commentCell = [[SDCCommentCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CommentCellID];
            //cell.cellInsetWidth = kSDCCellInsetWidth;
            commentCell.delegate = self;
        }

        PFObject *object = [parseObjectsArray objectAtIndex:indexPath.row];

        [commentCell setUser:[object objectForKey:kSDCActivityFromUserKey]];
        [commentCell setContentText:[object objectForKey:kSDCActivityContentKey]];
        [commentCell setDate:[object createdAt]];
        return commentCell;
    }
    default: {
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellID forIndexPath:indexPath];
        return cell;
    }
}

}

没关系..我只是想通了。我忘了添加viewDidLoad()

[self.tableView registerClass:[SDCCommentCell class] forCellReuseIdentifier:@"CommentCellIdentifier"];

UITableViewCell子类显示为空
