ios - 使用未声明的类型 "tagCell"错误。创建那种 xib 的 UICollectionViewCell

Question

我正在尝试构建标签流布局并且我正在关注这个主题；

http://codentrick.com/create-a-tag-flow-layout-with-uicollectionview/

然后这段代码抛出了这个错误:Use of undeclared type 'tagCell'。

var tagCell = collectionView.dequeueReusableCellWithReuseIdentifier("tagCell", forIndexPath: indexPath) as! tagCell

我创建了这些文件；一个名为 tagCell.xib 的 xib，一个名为 tagCell.swift 的文件。我把这些文件连接到 xib 的自定义类下。我不知道是什么问题，我没有遗漏地跟随主题。也许在 swift 2 中有一些关于它的变化。

我需要帮助。我寻找准备使用通过 swift 编写的库，但我没有找到。我现在必须自己编写代码。

有类(class)。

class tagCell: UICollectionViewCell {

    @IBOutlet weak var tagTitle: UILabel!
    @IBOutlet weak var plusLabel: UILabel!

    override func awakeFromNib() {
        self.backgroundColor = UIColor(red: 0.8, green: 0.8, blue: 0.8, alpha: 1)
        self.tagTitle.textColor = UIColor(red: 0.1, green: 0.1, blue: 0.1, alpha: 1)
        self.plusLabel.textColor = UIColor(red: 0.1, green: 0.1, blue: 0.1, alpha: 1)
        self.layer.cornerRadius = 4

    }

}

您需要在您的单元格上设置重用标识符。

只要打开你的 Storyboard，从 Collection View 中选择单元格并像下面这样设置它:

更新:

此外，您必须始终使用 CamelCase 命名您的类. 因此更改类名、.swift 文件名以及任何你想调用该类的地方，将其命名为 TagCell。断线现在应如下所示:

var tagCell = collectionView.dequeueReusableCellWithReuseIdentifier("tagCell", forIndexPath: indexPath) as! TagCell
