Question

I use a for-loop to create labels and buttons inside my scrollView. Is it possible to remove all objects indside my scrollView? (I would like to update it with new content)

for peop in personArray{

        scrollView.clearContent ??????


        // Name label
        var label: UILabel = UILabel()
        label.frame = CGRectMake(8, CGFloat(nameHeight), 183, 21)
        label.backgroundColor = UIColor.whiteColor()
        label.textColor =  UIColor(red: 90/255.0, green: 187/255.0, blue: 206/255.0, alpha: 1.0)
        label.textAlignment = NSTextAlignment.Left
        label.font = UIFont (name: "HelveticaNeue-Light", size: 14)
        label.text = " \(peop.getName()) - \(sex)"
        self.scrollView.addSubview(label)


        //Delete button
        var button = UIButton.buttonWithType(UIButtonType.System) as UIButton
        button.tag = playerId
        button.frame = CGRectMake(199, CGFloat(nameHeight), 37, 21)
        button.backgroundColor = colorWheel.colorsArray[7]
        button.setTitle("Slet", forState: UIControlState.Normal)
        button.addTarget(self, action: "delAction:", forControlEvents: UIControlEvents.TouchUpInside)
        button.setTitleColor(UIColor.whiteColor(), forState: UIControlState.Normal)
        self.scrollView.addSubview(button)
        button.titleLabel!.font = UIFont(name: "HelveticaNeue-Light", size: 14)


        scrollHeight = scrollHeight + 29
        nameHeight = nameHeight + 29
        playerId++
    }
    scrollView.contentSize = CGSize(width: 20.0, height: CGFloat(nameHeight))
}

func delAction(sender: UIButton!){
    personArray.removeAtIndex(sender.tag)
    updatePeople()
}

Have you tried this ?

let subViews = self.scrollView.subviews
for subview in subViews{
    subview.removeFromSuperview()
}
