IOS Swift3 how to delete custom UIView randomly
I am creating an iOS app in swift 3 where I am creating dynamic UIViews. I need to delete a custom view in a random way. Please help me, I have been stuck with this for a long time. thanks in advance
class ViewController: UIViewController {
var myView: subView!
var y : CGFloat!
@IBOutlet weak var addButton: UIButton!
override func viewDidLoad() {
y = 1
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func cancelbutton(_ sender: UIButton) {
myView.removeFromSuperview()
}
@IBAction func buttonAction(_ sender: Any) {
y = y + 110
myView = subView(frame: CGRect(x: 80, y: y, width: 300, height: 100))
myView.backgroundColor = UIColor.green
myView.actionButton.addTarget(self, action: (#selector(cancelbutton(_:))), for: UIControlEvents.touchUpInside)
self.view.addSubview(myView)
}
}
As you can see in the above image, when I click Close, the SubView (custome View) is closed, but where the MyView with green color does not go and stays there. Someone please help .........
required init?(coder aDecoder: NSCoder)
{
super.init(coder: aDecoder)
Bundle.main.loadNibNamed("subView",owner: self, options:nil)
self.addSubview(self.views)
Bundle.main.loadNibNamed("subView",owner: self, options:nil)
self.addSubview(self.views)
}
override init(frame: CGRect)
{
super.init(frame: frame)
Bundle.main.loadNibNamed("subView", owner: self, options: nil)
views.frame = bounds
self.addSubview(self.views)
}
@IBAction func buttonAction(_ sender: Any) {
views.removeFromSuperview()
}

What you are doing wrong is that you are adding multiple subViews that you have selected and not deleting. Please change your code as shown below. The thing is, whenever you add a new one subView
, you also set its tag value and when you select a view to remove its tag value and put a statement if
on that tag value.
class ViewController: UIViewController {
var myView: subView!
var y : CGFloat!
var tag : Int = 0
@IBOutlet weak var addButton: UIButton!
override func viewDidLoad() {
y = 1
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func cancelbutton(_ sender: UIButton)
{
let selectViewTagValue : Int = sender.tag /// save the selected view tag value
for object in self.view.subviews {
if ((object is subView) && object.tag == selectViewTagValue)
{
object.removeFromSuperview()
}
}
}
@IBAction func buttonAction(_ sender: Any) {
y = y + 110
myView = subView(frame: CGRect(x: 80, y: y, width: 300, height: 100))
myView.tag = tag
myView.actionButton.tag = tag
tag = tag + 1
myView.backgroundColor = UIColor.green
myView.actionButton.addTarget(self, action: (#selector(cancelbutton(_:))), for: UIControlEvents.touchUpInside)
self.view.addSubview(myView)
}
