Ios 将多个UICollectionViewCell推送到同一UIViewController
我有多个Ios 将多个UICollectionViewCell推送到同一UIViewController,ios,swift,uitableview,uicollectionview,Ios,Swift,Uitableview,Uicollectionview,我有多个UICollectionViewCell的UICollectionView，当我单击任何单元格时，它会将我推到另一个具有UITableView的UIViewController 我只希望每个UICollectionViewCell调用基于indexPath的特定API，并将响应放在UITableView中 例如： 如果我点击“牛肉”单元格，API会像“”一样，以此类推 我根本不使用故事板，我使用的是编程方法 家庭视图： protocol HomeViewDidSelectActionDe

您可以将类别数组项索引分配给UICollectionViewCell 然后，您可以在
didSelectItemAt func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let id = collectionView.cellForItem(at: indexPath)?.tag
let link = "https://apilink.com/recipes/random?search=\(categories[id])"
}
不清楚你在问什么。@kjoe每个单元格都有自己的API，当我单击它时，它必须获取，结果将放在UITableView中，我想要的是如何制作它当你说我想要的是如何制作它时，它是什么？退一步，暂时忘记你所知道的，试着从一个不知道你有什么问题的人的角度来阅读这个问题。你能指出你具体说问题出在哪里吗？你有代码，但问题不清楚你想要什么？点击collectionView时，将点击的对象ID/模型对象发送到详图视图，并根据需要下载data@Caleb很抱歉，如果我的问题不够清楚，我希望每个UICollectionViewCell调用基于indexPath的特定API，并将响应放在UITableView中。我不知道这是否足够清楚，请告诉meMaybe你是对的，但我不认为这对我有用，因为我使用了不同的方法（协议方法）。
