在DrEdit中列出Google云端硬盘中的所有文件和文件夹

如果要列出Google驱动器中的所有文件和文件夹，请使用此方法。

-(void)loadDriveFiles
{
GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];
query.q = [NSString stringWithFormat:@"'%@' IN parents", @"root"];
[self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                      GTLDriveFileList *files,
                                                      NSError *error) {
    if (error == nil)
    {
        driveFiles = [[NSMutableArray alloc] init]; // 
        [driveFiles addObjectsFromArray:files.items];

        for (GTLDriveFile *file in driveFiles)
             NSLog(@"File is %@", file.title);
    }
    else
    {
        NSLog(@"An error occurred: %@", error);
    }
}];
}

对于Mime类型，请参考此内容，并在使用或运算符的查询中使用它。

example- GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];
query.q = @" mimeType ='audio/mpeg' or mimeType ='audio/wav' or mimeType ='audio/aac' or mimeType ='audio/aiff'  or mimeType = 'video/mp4'  or mimeType = 'image/png' or mimeType = 'application/zip' ";
