iOS - Not able to add attachment, while launching gmail from my app

I am using MFMailComposeViewController to Compose email with attachment and it's working fine

Now I want to compose image with attachment with native email client. I am using code below

 NSString *customURL =[NSString stringWithFormat:@"googlegmail:///co?to=[t0]&subject=[subject]&body=[body]"];

    NSURL *url = [NSURL URLWithString:customURL];
    if ([[UIApplication sharedApplication]
         canOpenURL:url])
    {

        [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:^(BOOL success) {

            NSLog(@"%d",success);
        }];
    }
    else
    {
        //not installed, show popup for a user or an error
    }

It's working fine with subject and Body, but I am not able to attach attachments(ie:Zip file, screen shots).

is there any way to add attachment, while using gmail or any other client app.
