I have added an image(A) in my PDF file. However, when I click on image A to add an image to overwrite image A, the delegate I receive is as follows
override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, onTouchesCancelled touches: Set, with event: UIEvent?) → Bool {

I should have received the function call from
override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, onTouchesEnded touches: Set, with event: UIEvent?) →

I don’t know why this error occurs.

Please describe your issue and provide steps to reproduce it:

class CustomImageTool: CustomToolBase {
    private var startPosition: PTPDFPoint!
    private var readyFirstPosition: Bool = false
    private var clickPoint: PTPDFPoint? = nil
    private var imageGeometry: PTAnnot!
    private var uuid: String = ""
    private let DIVIDE_BY: Double = 8

    required init(pdfViewCtrl: PTPDFViewCtrl) {
        super.init(pdfViewCtrl: pdfViewCtrl)
    }
        
    override class var createsAnnotation: Bool {
        return true
    }

    override var annotClass: AnyClass {
        return CustomImageTool.self
    }

    override var annotType: PTExtendedAnnotType {
        return .imageStamp
    }
    
    override func getToolType() -> CustomToolType {
        return CustomToolType.image
    }

    override var allowScrolling: Bool {
        return false
    }

    override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, handleTap gestureRecognizer: UITapGestureRecognizer) -> Bool {
        return true
    }
    
    override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, onTouchesBegan touches: Set<UITouch>, with event: UIEvent?) -> Bool {
        let numberOfTouches = touches.count

        return true
    }
    
    override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, onTouchesMoved touches: Set<UITouch>, with event: UIEvent?) -> Bool {
        return true
    }
    
    override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, onTouchesEnded touches: Set<UITouch>, with event: UIEvent?) -> Bool {
      // todo : add image
        return true
    }
    
    override func pdfViewCtrl(_ pdfViewCtrl: PTPDFViewCtrl, onTouchesCancelled touches: Set<UITouch>, with event: UIEvent?) -> Bool {
       // todo : canceled
        return true
    }
