You can use the URL scheme Gmail to create a subclass of UIActivity:

The code below was extracted this answer: https://stackoverflow.com/a/12766330/3726577

//ActivityViewCustomActivity.h
@interface ActivityViewCustomActivity : UIActivity

@end

//ActivityViewCustomActivity.m
@implementation ActivityViewCustomActivity

- (NSString *)activityType {
    return @"googlegmail";
}

- (NSString *)activityTitle {
    return @"Gmail";
}

- (UIImage *)activityImage {
    // Note: These images need to have a transparent background and I recommend these sizes:
    // iPadShare@2x should be 126 px, iPadShare should be 53 px, iPhoneShare@2x should be 100
    // px, and iPhoneShare should be 50 px. I found these sizes to work for what I was making.

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        return [UIImage imageNamed:@"iPadShare.png"];
    }
    else
    {
        return [UIImage imageNamed:@"iPhoneShare.png"];
    }
}

- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems {
    NSLog(@"%s", __FUNCTION__);
    return YES;
}

- (void)prepareWithActivityItems:(NSArray *)activityItems {
    NSLog(@"%s",__FUNCTION__);
}

- (UIViewController *)activityViewController {
    NSLog(@"%s",__FUNCTION__);
    return nil;
}

- (void)performActivity {
    NSString *email = @"googlegmail:///co?subject=Check it out&body=Check the application";
    email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];

    [self activityDidFinish:YES];
}

@implementation ViewController2

- (void)viewDidLoad{
    [super viewDidLoad];

    NSString *textItem = @"Check the application";

    ActivityViewCustomActivity * ca = [ActivityViewCustomActivity new];

    UIActivityViewController *activityVC =
    [[UIActivityViewController alloc] initWithActivityItems:@[textItem] applicationActivities:[NSArray arrayWithObject:ca]];

    activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll];
    [activityVC setValue:@"Check it out" forKey:@"subject"];

    activityVC.completionHandler = ^(NSString *activityType, BOOL completed)
    {
        NSLog(@" activityType: %@", activityType);
        NSLog(@" completed: %i", completed);
    };

    [self presentViewController:activityVC animated:YES completion:nil];
}
