UICollectionView cell.ViewWithTag 为 UILabel 返回 nil [英] UICollectionView cell.ViewWithTag returning nil for UILabel

问题描述

这个标签似乎返回 nil，即使我正确设置了重用标识符和标签.

This label seems to return nil, even though I have the reuseIdentifier and tag set properly.

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    var identifier: String = "CollectionCell"
    var cell: UICollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier(identifier, forIndexPath: indexPath) as! UICollectionViewCell

    // Configure the cell


    //save till later, when images are actually present

    //var cellItem1 = hostManager[indexPath.row * 2]

    let label:UILabel = cell.viewWithTag(1) as! UILabel
    return cell

}

程序在标签设置为 viewWithTag 的地方中断.我没有为单元设置自定义类，只有原型.标签设置在情节提要上.收到错误EXC_BAD_INSTRUCTION...".任何帮助将不胜感激，谢谢！

The program breaks where the label is set = to the viewWithTag. I have no custom class set for the cell, just the prototype. The tag is set on the storyboard. Getting an error "EXC_BAD_INSTRUCTION...". Any help would be appreciated, Thanks!

推荐答案

尝试从 viewDidLoad 中删除这一行:

Try removing this line from viewDidLoad:

self.collectionView!.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier)
