Question

我正在使用photoEditing应用程序，我需要在其上添加贴纸，我有一个视图名称是viewImageBackground，在此视图中我有一个图像视图。使用以下代码我在图像视图上添加贴纸。

    if selectedPhotos == "Goodies" {

            switch indexPath.row {

            case 0:
                addStickers(#imageLiteral(resourceName: "Goodies-1.png"))

                break
            case 1:
                addStickers(#imageLiteral(resourceName: "Goodies-2.png"))

                break
            case 2:
                addStickers(#imageLiteral(resourceName: "Goodies-3.png"))

                break
            case 3:
                addStickers(#imageLiteral(resourceName: "Goodies-4.png"))

                break

            default:
                break
            }
        }

添加贴纸功能

    func addStickers(_ imgImage: UIImage) {

    hideTextButtons()

    textView = UIView(frame: CGRect(x: 100, y: 100, width: 100, height: 100))
    textView?.backgroundColor = UIColor.clear
    viewImgBackground.addSubview(textView!)

    //Content view

    gesture = "Stickers"

    var imgSticker  = UIImageView(frame: CGRect.init(x: 0.0, y: 0.0, width: 80, height: 80))
    imgSticker.image = imgImage
    imgSticker.contentMode = UIViewContentMode.scaleAspectFill

    imgSticker.isUserInteractionEnabled = true
    imgSticker.isMultipleTouchEnabled = true

    textView?.addSubview(imgSticker)

    deleteView = UIImageView(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
    deleteView?.backgroundColor = UIColor.clear
    deleteView?.image = UIImage(named: "close_gold.png")
    deleteView?.isUserInteractionEnabled = true
    let singleTap = UITapGestureRecognizer(target: self, action: #selector(self.singleTap))
    deleteView?.addGestureRecognizer(singleTap)
    textView?.addSubview(deleteView!)

    panGesture = UIPanGestureRecognizer.init(target: self, action: #selector(handlePanGesture(_:)))
    panGesture.delegate = self

    pinchGesture = UIPinchGestureRecognizer.init(target: self, action: #selector(handlePinchGesture(_:)))
    pinchGesture.delegate = self

    textView?.addGestureRecognizer(panGesture)
    textView?.addGestureRecognizer(pinchGesture)

    rotateView = UIImageView(frame: CGRect(x: 0, y: (textView?.frame.size.height)! - 25, width: 25, height: 25))
    rotateView?.backgroundColor = UIColor.clear
    rotateView?.image = UIImage(named: "button_01.png")
    rotateView?.isUserInteractionEnabled = true
    textView?.addSubview(rotateView!)

    let panRotateGesture = UIPanGestureRecognizer(target: self, action: #selector(self.rotateViewPanGesture))
    rotateView?.addGestureRecognizer(panRotateGesture)
    panRotateGesture.require(toFail: panRotateGesture)

    let snapshotImage = UIImage.imageWithView(view: viewImgBackground)
    count += 1

    logoImages.append(snapshotImage)


}

现在我的观点如下图所示

现在的问题是，我需要使用此代码添加多个贴纸手势我的条件是满意的50％贴纸添加到手势的图像视图但我需要添加多个贴纸，这意味着每当我点击每个贴纸新的imageview与需要添加贴纸，但此代码只会添加一个贴纸并替换贴纸内部视图。我该如何实现呢？

注意：每当我点击重置按钮我需要删除所有这些贴纸，所以你在这里宣布imgSticker作为一个局部变量，这是不值得的所以我该怎么做才能添加多个贴纸图像视图。

请帮助，谢谢！
