Answer 1

You should make another uinavigationcontroller and present uiactivityviewcontroller from there. In this code _image is a UIImage yo wan to share. BlankViewController is just place holder viewcontroller you can create in IB you can also make it's view's background colour to clear and do what ever appearance changes you want to do.

__weak  CurrentViewController  *weakSelf    =   self  ;

UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[_image] applicationActivities:nil]   ;
UIViewController        *viewC  =   [[UIViewController alloc] initWithNibName:@"BlankViewController" bundle:nil] ;
UINavigationController  *navC   =   [[UINavigationController alloc] initWithRootViewController:viewC]  ;
activityViewController.completionHandler = ^(NSString *activityType, BOOL completed)
{
    [weakSelf dismissViewControllerAnimated:NO completion: ^ {
        ;    // Your completion handler
    }]  ;
};
[self presentViewController:navC animated:NO completion: ^ {
    [navC presentViewController:activityViewController animated:YES completion: ^ {
        ;
    }]  ;
}];
