Ich habe eine SWRevealViewController-Anwendung. Ich habe erfolglos versucht, die Hintergrundfarbe mit self.view.backgroundColor zu setzen. Das Beispiel, das ich unten zeige, ist ein UIViewController, der eine tableView mit einer leeren UIView() - Fußzeile enthält, um die tableView zu beenden, wenn sie fertig ist. Ich versuche, die Hintergrundfarbe zu setzen, um den restlichen Raum zu füllen. Mein Code unten.Self.view.backgroundColor funktioniert nicht

Der von Ihnen angegebene Code _never_ versucht, 's zu setzen elf.view.backgroundColor', Ihre Frage ergibt also keinen Sinn. – matt
Entschuldigung, ich habe es wieder bearbeitet. Ich hatte es früher aus Frustration herausgenommen und versucht, andere Lösungen zu finden. – Praveen
