現在、firebaseデータベースのコンテンツが読み込まれているtableViewがあります。私は、セルに埋め込まれるべき特定の情報を印刷することができ、物理的にセルにデータが取り込まれていて、データが取り込まれた適切な長さにスクロールすることができます。なぜ情報にアクセスして細胞を移植するのか、データを細胞に挿入しないのかどうかはわかりません。TableViewには行は埋め込まれていますが、内容はありません
のtableView：

class Articles: UITableViewController {
var vcType:String = "Home"
//var valueTopass = [[String:String]]()
var rooms = [Room]()
var articleCell = ArticlesCell()

override func viewDidLoad() {
super.viewDidLoad()
if self.vcType == "Home"
{
self.rooms += ArticlesManager.sharedClient.rooms
}
else
{
if let obj = ArticlesManager.sharedClient.catRooms[self.vcType.lowercased()] //as? [Room]
{
self.rooms += obj

'reloadData'または' cellForRowAt'メソッドの中の他のテーブル更新メソッドを決して呼び出さないでください。悪い、悪い、悪い。それらの呼び出しを取り出し、何が起こるかを見てください。 – rmaddy
無関係ですが、なぜ 'NSIndexPath'のすべての用途ですか？ 'IndexPath'を使用してください。 – rmaddy
