In meinem Projekt habe ich die linke Ansicht und die rechte Ansicht erstellt, es zeigt dynamisch zwei verschiedene Ansichten, Linke Seite erstellen FirstView und die FirstView innerhalb zeigen Titel, Kommentare, Bild und Video. Und auch RightView-Seite erstellen secondView innerhalb Show Titel, Kommentare, Bild und Video. Bild und Video zeigen nur einige der Ansichten. Das Design ist komplett programmatisch erstellt, mein Design unten gegeben wird,UIButton Aktion ruft Swift nicht auf?
Mein Problem Play-Taste (UIButton) Aktion nicht aufgerufen wird, warum?
Ich weiß nicht, ist meinen Code unten geben, UIButton Name: btnPlay, Aktion Name: buttonAction:
import UIKit

@IBOutlet weak var scrollViewBase: UIScrollView!

var rightView = UIView()
var wholeYLeft = CGFloat()
var wholeYRight = CGFloat()
let btnPlay = UIButton()
var myArrayOfDict: NSArray = [

Ich mache etwas ähnliches. Was ist lblInset in deinem Code? – nadi9
seine benutzerdefinierte Klasse für 'UILabel' –
groß. Vielen Dank für Ihre Hilfe – nadi9
