我正在工作的应用程序中，我必须保存图像本地，我使用的领域为此，该应用程序采取让我们说，10到40图像一次从图库，并开始写入图像到领域本地数据库和冻结的屏幕在写入过程中，请我如何修改我的代码，使我的应用程序不会冻结在写入事务期间，我被困在这种情况下，任何帮助将不胜感激，谢谢

let imagesAdd = refObject.1
let imageobjectArray = modelObject as! [FacilitiesImagesModel]
do{
    for imageObject in imageobjectArray{
         try realmObj.write {
              imagesAdd?.facilitiesImages.append(imageObject)
             }
     }

     completionHandler(true, "")

 }catch let err{
      realmObj.cancelWrite()
      completionHandler(false, err.localizedDescription)
 }

以下是我的完整方法，我删除了不属于我的问题的额外代码

struct RealmCRUD {

private let realmObj = try! Realm()

func create<T>(modelObject: T, modelObjectType: ModelType, refObject: (PropertyModel?, FacilitiesModel?), completionHandler: @escaping ((Bool, String) -> Void)){

    switch modelObjectType {

    case .FacilitiesImagesModel:
        let imagesAdd = refObject.1
        let imageobjectArray = modelObject as! [FacilitiesImagesModel]
        do{
            for imageObject in imageobjectArray{
                try realmObj.write {
                    imagesAdd?.facilitiesImages.append(imageObject)
                    }
            }

            completionHandler(true, "")

        }catch let err{
            realmObj.cancelWrite()
            completionHandler(false, err.localizedDescription)
        }
        break
    }

    default:
    break
}

我正在从其他类调用此方法，如下所示：

func dismissComplete() {

    var arrayOfFacilitiesImagesModelObj = [FacilitiesImagesModel]()

    for photos in self.selectedAssets{

        if let photo = photos.fullResolutionImage{
            let facilitiesImagesModelObj = FacilitiesImagesModel()
            facilitiesImagesModelObj.facilityPhoto = photo.jpegData(compressionQuality: 0.5)!
            arrayOfFacilitiesImagesModelObj.append(facilitiesImagesModelObj)
        }else{
            print("Unable to select facility photos")
        }

    }

    self.realmCrudObj.create(modelObject: arrayOfFacilitiesImagesModelObj, modelObjectType: .FacilitiesImagesModel, refObject: (nil,self.realmFacilitiesResults), completionHandler: { (success, error)  in

        self.collectionViewReference?.reloadData()

        ProgressHUD.dismiss()

        if !success{
            self.showAlert(title: "Error", description: error)
        }
        })
}

并且我将选择的属性数据传递给这个类中的这个变量

var realmFacilitiesResults: FacilitiesModel?

这是我的设施模型

class FacilitiesModel: Object {

@objc dynamic var facilityName = ""

let facilitiesImages = List<FacilitiesImagesModel>()

let parentProperty = LinkingObjects(fromType: PropertyModel.self, property: "facilities")

}
