Ich habe ein Uitextfield programmgesteuert erstellt, wodurch das Uitextfield eine Eigenschaft des ViewController erstellt wird. Ich muss die Tastatur mit der Rückkehr und der Berührung auf dem Bildschirm entlassen. Ich konnte den Bildschirm Touch in die Entlassung bringen, aber das Drücken der Rückkehr funktioniert nicht. Möglich zu tun?[code]#import
