Tablo Manzara modunda telefonu yerleştirdiğimde yalnızca yükleri göster

Question

Uygulamayı çalıştırdığımda, yüklü olmadığı, ancak telefonumu yatay moda getirdiğimde boş girişleri gösteren özel bir tablo görünümü var. Görünüşe göre, bana gerçekten mantıklı gelmiyor. Baska öneri?

Answer 1

Alamofire.request doğada zaman uyumsuz olmasıdır. Bu nedenle, tablo ilk yüklendiğinde, istek hala devam ediyor ve draftStandings ürününüzde veri yok. Döndürdüğünüzde, tablo yeniden yüklenir ve o zamana kadar draftStandings tablonun gösterdiği bazı veriler vardır.

İstek yanıtında draftStandings ayarladıktan sonra tableView.reloadData() eklemeye çalışın.
