IOS 10 - Swift 3.0: Arrête la fonction déléguée pour enregistrer l'image

Question

Je crée une application avec swift 3, xCode 8.2 et IOS10. L'interface dispose d'un écran de vision thermique (FLIR ONE). Ma question est, comment puis-je prendre une photo? Mon code est:

import UIKit 

class ThermalCameraVC: UIViewController, FLIROneSDKImageReceiverDelegate, FLIROneSDKStreamManagerDelegate { 


    //MARK: OUTLETS 
    @IBOutlet weak var imageView: UIImageView! 
    @IBOutlet weak var labelStatusCamera: UITextField! 
    @IBOutlet weak var labelCargeCamera: UITextField! 
    @IBOutlet weak var icnCancelPicture: UIButton! 
    @IBOutlet weak var icnUploadPicture: UIButton! 
    @IBOutlet weak var iconTakePicture: UIButton! 


    //MARK: VARIABLES 
    var simulatorStatus = false 
    var cameraBussy = false 


    override func viewDidLoad() { 
     super.viewDidLoad() 
     FLIROneSDKStreamManager.sharedInstance().addDelegate(self) 
     FLIROneSDKStreamManager.sharedInstance().imageOptions = FLIROneSDKImageOptions(rawValue: FLIROneSDKImageOptions.blendedMSXRGBA8888Image.rawValue)! 

     icnCancelPicture.isHidden = true 
     icnUploadPicture.isHidden = true 
    } 

    //MARK: CANCEL PICTURE 
    @IBAction func cancelPicture(_ sender: Any) { 
     cameraBussy = false 
    } 


    //MARK: UPLOAD PICTURE AMAZON S3 
    @IBAction func uploadPicture(_ sender: Any) { 


    } 

    func flirOneSDKDelegateManager(_ delegateManager: FLIROneSDKDelegateManager!, didReceiveBlendedMSXRGBA8888Image msxImage: Data!, imageSize size: CGSize){ 
    let image = FLIROneSDKUIImage(format: FLIROneSDKImageOptions.blendedMSXRGBA8888Image, andData: msxImage, andSize: size) 

     //HERE I NEED TO STOP THE DELEGATED FUNCTION TO SAVE THE IMAGE !! 
     if self.cameraBussy{ 
      //cameraBussy = false 

     }else{ 
      DispatchQueue.main.async{ 

       self.imageView.image = image 
      } 

     } 
    } 

    @IBAction func takeThermalPicture(_ sender: Any) { 
     cameraBussy = true 
     icnCancelPicture.isHidden = false 
     icnUploadPicture.isHidden = false 
     iconTakePicture.isHidden = true 
    } 

    } 

Comment puis-je arrêter le flux de données dans cette fonction déléguée? Parce qu'il appelle continuellement.

Définissez la valeur du délégué sur zéro.

@IBAction func takeThermalPicture(_ sender: Any) { 

     FLIROneSDKStreamManager.sharedInstance().addDelegate(nil) 
     cameraBussy = true 
     icnCancelPicture.isHidden = false 
     icnUploadPicture.isHidden = false 
     iconTakePicture.isHidden = true 

    }
