Die Leute sagen mir, wie ich aus meiner Position herauskommen und so tun, dass, wenn ein neues Ereignis hinzugefügt wird, es der Anfang, nicht das Ende wird. Ich werde sehr dankbar für die Hilfe sein.Wie wird die erste neue Zeile in TableViewCell (swift) eingefügt?
Ich habe drei Arrays und ich hatte sie von den Elternzellen zu sortieren, und in dieser Linie, die ich sehr viel gespielt func Tableview (_ Tableview: UITableView, numberOfRowsInSection Abschnitt: Int) -> Int

Bitte nicht werfen Sie Ihre gesamte View-Controller-Code und erwarten, dass wir das Problem zu finden. Erstellen Sie stattdessen ein [mcve], das das Problem reproduziert und das veröffentlicht. – JAL
was Sie suchen. Könnten Sie das im Detail erläutern? –
Ich möchte die neue Zeile als erste hinzufügen –
