ios - iOS中的Google Drive集成可上传PDF文件

我正在iOS 8中开发应用程序，并且通过安装以下Pod集成了Google云端硬盘:

pod platform :ios, '8.0'

pod 'GoogleAPIClient/Drive', '~> 1.0.0'
pod 'GTMOAuth2', '~> 1.1.0'

当我放置代码以上传PDF文件时，出现以下错误:

在类型'GTLDriveFile *'的对象上找不到属性'title'

使用未声明的标识符'GTLDriveParentReference'。

选择器'queryForFilesInsertWithObject:uploadParameters:'的未知类方法。

这是我的代码:

GTLDriveFile *driveFile = [GTLDriveFile object];

driveFile.mimeType = @"application/pdf";
driveFile.originalFilename = @"database.pdf";
driveFile.name = @"database.pdf";
driveFile.size = fileSizeNumber;
NSString *parentId = @"root";
driveFile.parents = @[parentId];

NSData *fileContent = [[NSData alloc] initWithContentsOfFile:fileName];
GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:fileContent MIMEType:@"application/pdf"];


GTLDriveParentReference *parentRef = [GTLDriveParentReference object];
parentRef.identifier = folderIdentifier; // identifier property of the folder
driveFile.parents = @[ parentRef ];

GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:driveFile uploadParameters:uploadParameters];

[self.service executeQuery:query
              completionHandler:^(GTLServiceTicket *ticket,
                                  GTLDriveFile *updatedFile,
                                  NSError *error) {
                  if (error == nil) {
                      NSLog(@"\n\nfile uploaded into google drive\\<my_folder> foler");
                  } else {
                      NSLog(@"\n\nfile uplod failed google drive\\<my_folder> foler");
                  }
              }];

最佳答案

使用driveFile.name代替driveFile.title

没有GTLDriveParentReference类，因此删除这些行。

使用queryForFilesCreateWithObject代替queryForFilesInsertWithObject
