关于GKPhoto点击放大没有图片只有缺省图

GKPhoto,点进去看看,人家可传递的不止有url,还有UiImage

NSString *photo = self.detailModel.teacherModel.teacher_picture;
        NSString *placeHoldStr = @"ing_morentouxiang";
        NSMutableArray *photos = [NSMutableArray new];
        GKPhoto *photoModel = [GKPhoto new];
        photoModel.url = [NSURL URLWithString:photo ? photo : @""];
        photoModel.placeholderImage = [UIImage imageNamed:placeHoldStr];
        [photos addObject:photoModel];

        //                    if let realurl = URL(string: "https://img2-xz.veimg.cn/TeacherPic/2023062817210128.jpg"){
//                            if let realurl = URL(string: "https://img2-xz.veimg.cn/TeacherPic/2023062817210128.jpg"){
//                                photoModel.url = realurl
//                                photoModel.originUrl = realurl
                                photoModel.image = value.image
//                                print(realurl,"realurl1024")
//                            }
                            photoModel.placeholderImage = UIImage(named: placeHoldStr)

                            photos.append(photoModel)
                            imageView.isUserInteractionEnabled = true
                            imageView.addTapGesture {
                                self?.showAction(photos)
                            }

    func showAction(_ photos: [GKPhoto]) {
        let browser = GKPhotoBrowser(photos: photos, currentIndex: 0)
        browser.showStyle = .none
        browser.loadStyle = .determinate
        browser.isFullWidthForLandScape = false
        browser.isStatusBarShow = true
        browser.view.setNeedsLayout()
        browser.view.layoutIfNeeded()
        // let fromVC = UIApplication.shared.delegate?.window??.rootViewController
        if let vc = self.getviewController(){
            browser.show(fromVC:vc)
        }
     
    }
    public func getviewController()->UIViewController? {

          var nextResponder: UIResponder? = self

          repeat {
              nextResponder = nextResponder?.next

              if let viewController = nextResponder as? UIViewController {
                  return viewController
              }

          } while nextResponder != nil

          return nil
      }
