我使用for循环在scrollView中创建标签和按钮.
是否可以删除我的scrollView中的所有对象？ (我想用新内容更新它)

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(199,37,21)
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()
}
解决方法
你试过这个吗？
let subViews = self.scrollView.subviews
for subview in subViews{
subview.removeFromSuperview()
}
