如何列出多个Mime类型文件来自Google云端硬盘？

Question

我想列出来自Google Drive的mp3,mp4,mkv,avi,aac,wmv文件,现在我只能列出mp3文件,但我想列出其他扩展文件......
我怎么能利用query.q = @"mimeType ='audio/mpeg'"; 用于多个扩展

//我试过这个

-(void)loadDriveFiles
{

GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];

query.q = @"mimeType ='audio/mpeg' ";




UIAlertView *alert = [GoogleUtilities showLoadingMessageWithTitle:@"Loading files"

                                                         delegate:self];

[self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,

                                                          GTLDriveFileList *files,

                                                          NSError *error) 
{       
    [alert dismissWithClickedButtonIndex:0 animated:YES];

    if (error == nil)
    {

        if (self.driveFiles == nil) 
        {     
            self.driveFiles = [[NSMutableArray alloc] init];

        }

        [self.driveFiles removeAllObjects];           
        [self.driveFiles addObjectsFromArray:files.items];         
        [self.tableView reloadData];

    } else {

        NSLog(@"An error occurred: %@", error);

        [GoogleUtilities showErrorMessageWithTitle:@"Unable to load files"

                                           message:[error description]

                                          delegate:self];

    }

}];
}
// Thanks In Advance
