Ios 崩溃：com.apple.main-thread BasePostCell.collectionView（u3;：cellForItemAt:）

我从crashlytics公司撞车了，你能告诉我这是什么原因吗？它是连接到AuthManager还是BasePostCell

此崩溃表明在cellForItemAt委托方法中生成单元格时存在问题，因此首先尝试重新生成此问题，该问题提供了有关crashI的更多详细信息，但无法在设备或模拟器上复制此问题。请共享您的集合视图委托code@SilverskyTechnology如果您在这里显示控制台日志中打印的崩溃原因，那就太好了！不会生成崩溃，但我认为这一行中的单元格中存在问题“collectionView.dequeueReusableCell（for:indexPath）as FeedPostCarouselCollectionViewCell”正确的方法是“let cell=collectionView.dequeueReusableCell（with ReuseIdentifier:“FeedPostCarouselCollectionViewCell”，for:indexPath）as！FeedPostCarouselCollectionViewCell”

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return assets.count == 1 ? 0 : assets.count
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(for: indexPath) as FeedPostCarouselCollectionViewCell
    if !assets.isEmpty {
        let photo = assets[indexPath.row]
        cell.configure(with: photo)
    }
    return cell
}
