OffLine时,FIRStorageUploadTask putData无法完成

Question

我正在尝试处理用户在应用程序离线时尝试上传和映像时会发生什么.有时它工作,firebase完成一个域错误,我能够创建一个上传任务,但是,如果设备离线,我最近永远不会调用完成块,我得到一个不在firebase文档中的日志消息.

以下是上传图片的代码:

[self.storageRef child:imagePath] putData:imageData metadata:fileMeta
    completion:^(FIRStorageMetadata * _Nullable metadata, NSError * _Nullable error) {
        if (error) {
            NSLog(@"Error uploading: %@", error);
            //create local task
            [self createUploadTaskForCurrentUserWithContentType:fileMeta.contentType filePath:imagePath isPhoto:NO];
            return;
        }
        NSLog(@"Project image upload successful");        
    }];

这是我在网上重新上线后得到的日志消息:

}

注意:这在联机时工作正常,唯一的问题是当我尝试在离线时运行代码时.
