diese Frage wurde schon viele Male hier erwähnt, aber mein Fall ist etwas anders, was ich tue, dass es eine zwei UITableViewController in UITabBarController gibt, wenn ich zum zweiten UITableViewController die CellForRowAtIndextPath-Methode nicht zum Füllen der UITableViewController gefeuert wird mit den Daten, die von meinem Server mit AFNetworking nach der Suche für viele Lösung über das Internet die ganze Frage gezogen werden, dass ich wie question 1, question 2, question 3, question 4, question 5,cellForRowAtIndexPath nicht innerhalb UITabBarController aufgerufen
sie nicht enthalten UITabBarController gefunden e ist der Code, den ich zu verwenden Ich versuche:

Können Sie ein NSLog von do [Ereignisse zählen] innerhalb numberOfRowsInSection –
es mir auch in zwei Fall geben Null, wenn ich AFHTTPrequest innen RowForIndexPath tue oder mit ViewDidLoad –
vielleicht weil Ihre Anfrage Null Elemente zurückgeben oder liege ich falsch? –
