ios-Google硬盤列出多個mime類型文件

Google硬盤列出多個mime類型文件

要從谷歌硬盤中類出 mp3,mp4,mkv,avi,aac,wmv 文件。目前我只能列出mp3文件。
我的代碼
怎麼使用query.q = @"mimeType ='audio/mpeg' 查詢多個擴展？

-(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];   
    }
}];
}
//非常感謝

最佳回答：

在查詢中使用邏輯運算符

比如mimeType = 'audio/mpeg' or mimeType = 'audio/mp3'
