Delete ImageView From SubScrollView In Swift - swift

Question

I am having main ScrollView with pages Enable..Under that I have Subscrollviews and ImageView to display images..I want to Delete Selected image from main scrollview..I don't have any idea to how to get that selected imageView from scrollview and remove it...Here is my code...
func createScroll()
{
var arrayImage = NSUserDefaults.standardUserDefaults().objectForKey("ImageArray") as NSMutableArray
var index = NSUserDefaults.standardUserDefaults().objectForKey("Index") as Int
var scroll = UIScrollView(frame: CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height))
var page = UIPageControl(frame: CGRectMake(0, 0, scroll.frame.size.width, scroll.frame.size.height))
page.numberOfPages = arrayImage.count
page.currentPage = 0
page.autoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth
scroll.contentSize = CGSizeMake(scroll.frame.size.width * CGFloat(arrayImage.count - 1) , 0)
scroll.delegate = self
scroll.pagingEnabled = true
scroll.maximumZoomScale = 6
scroll.minimumZoomScale = 0.5
scroll.tag = Tags.Tag_MainScroll.rawValue
scroll.addSubview(page)
view.addSubview(scroll)
scroll.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight
scroll.contentOffset = CGPointMake(scroll.frame.size.width * CGFloat(index - 1) , 0)
}
//MARK: Display Selected Image
func displayImage()
{
var mainScroll : UIScrollView = view.viewWithTag(Tags.Tag_MainScroll.rawValue) as UIScrollView
var arrayImage = NSUserDefaults.standardUserDefaults().objectForKey("ImageArray") as NSMutableArray
var xPosition : CGFloat = 0
for i in 1...22
{
var subScroll = UIScrollView(frame: CGRectMake(xPosition, 0, view.frame.size.width, view.frame.size.height))
subScroll.delegate = self
subScroll.maximumZoomScale = 6
subScroll.minimumZoomScale = 0.5
subScroll.tag = Tags.Tag_SubScroll.rawValue + i
mainScroll.addSubview(subScroll)
var imgToDisplay : UIImage = UIImage(named: "\(arrayImage[i])")! as UIImage
var imgView : UIImageView = UIImageView(frame: CGRectMake((subScroll.frame.size.width - 100 ) / 2,(subScroll.frame.size.height - 100) / 2, 100, 100))
subScroll.contentSize = CGSizeMake(imgView.frame.size.width, imgView.frame.size.height)
imgView.image = imgToDisplay
imgView.tag = Tags.Tag_imgView.rawValue
subScroll.addSubview(imgView)
xPosition += subScroll.frame.size.width
}
}
Here Is my Delete Function...
func Delete()
{
var imgView : UIImageView? = view.viewWithTag(Tags.Tag_imgView.rawValue) as? UIImageView
var scroll : UIScrollView = view.viewWithTag(Tags.Tag_MainScroll.rawValue) as UIScrollView
for img in scroll.subviews
{
imgView = img as? UIImageView
imgView?.removeFromSuperview()
}
}`

Answer 1

HERE is the reference

Answer 2

as per my code this Delete Function is working for me
func Delete()
{
var imgView : UIImageView? = view.viewWithTag(Tags.Tag_imgView.rawValue) as? UIImageView
var scroll : UIScrollView = view.viewWithTag(Tags.Tag_MainScroll.rawValue) as UIScrollView
var number : Int = Int(scroll.contentOffset.x / scroll.frame.size.width)
var page : UIPageControl = view.viewWithTag(Tags.Tag_page.rawValue) as UIPageControl
page.currentPage = number
println("\(page.currentPage)")
if var array : NSArray = NSUserDefaults.standardUserDefaults().objectForKey("ImageArray") as? NSArray
{
arrayImage = array.mutableCopy() as NSMutableArray
}
page.removeFromSuperview()
number++
arrayImage.removeObjectAtIndex(number)
NSUserDefaults.standardUserDefaults() .setObject(arrayImage, forKey: "ImageArray")
println("\(arrayImage[number])")
println("\(arrayImage)")
NSUserDefaults.standardUserDefaults().synchronize()
displayImage()
}
