iOS在Google Drive Api上使用上载图像（错误“GTLServer中的断言失败…”）

我正在尝试在我的iOS应用程序中使用Google Drive。尝试上载文件时，出现以下错误：

2013-06-17 14:38:57.964 GTL Demo[6495:11303] *** Assertion failure in -[GTLService uploadFetcherWithRequest:fetcherService:params:](), /Users/huylx612/demo2/google-api-objectivec-client-read-only/Source/Objects/GTLService.m:565

这是我的相关代码：

- (void)uploadPhoto:(UIImage*)image
{
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"'Quickstart Uploaded File ('EEEE MMMM d, YYYY h:mm a, zzz')"];
    GTLDriveFile *file = [GTLDriveFile object];
    file.title = [dateFormat stringFromDate:[NSDate date]];
    file.descriptionProperty = @"Uploaded from the Google Drive iOS Quickstart";
    file.mimeType = @"image/png";

    NSData *data = UIImagePNGRepresentation((UIImage *)image);

    GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:data MIMEType:file.mimeType];
    GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:file
                                                       uploadParameters:uploadParameters];
    UIAlertView *waitIndicator = [self showWaitIndicator:@"Uploading to Google Drive"];

    [self.driveService executeQuery:query
                       completionHandler:^(GTLServiceTicket *ticket,GTLDriveFile *insertedFile, NSError *error)
                {
                      [waitIndicator dismissWithClickedButtonIndex:0 animated:YES];
                      if (error == nil)
                      {
                          NSLog(@"File ID: %@", insertedFile.identifier);
                          [self showAlert:@"Google Drive" message:@"File saved!"];
                      }
                      else
                      {
                          NSLog(@"An error occurred: %@", error);
                          [self showAlert:@"Google Drive" message:@"Sorry, an error occurred!"];
                      }
                }];
}
