Bin ein Anfänger in iOS, erstellt eine Anwendung mit Hilfe der Tabellenansicht. Ich starte nur meine Anwendung, während die App ausgeführt wird, ruft die App nicht die Methode cellForRowIndexPath auf. Verwende Json als Webservice. Im Ausgabefenster werden die Parsing-Daten angezeigt, es wird jedoch nicht im Simulator angezeigt. Ich legte Haltepunkt und ich verstand, dass der CellForRowIndexPath-Pfad nicht aufgerufen wurde. Ich ziehe Datenverkehr und Datendelegat in Dateien onner der XIB-Datei. aber nichts geschieht ... die Tabellenansicht ist erhalten die Anzeige aber noch keine Inhalte ... geschraubt bin .. Jeder bitte helfen Sie mir ...Die Methode cellForRowAtIndexPath-Methode wurde nicht aufgerufen
