Answer 1

If you want to present vc3 from vc1 modally after dismissing vc2, you can present vc3 programmatically in the completion block of your dismiss method which you currently have set to nil. For instance you could write:

[self dismissViewControllerAnimated:YES completion:^{
    UIViewController *vc3 = [[UIStoryboard storyboardWithName:@"storyboardName" bundle:nil] instantiateViewControllerWithIdentifier:@"vc3Identifier"];
    [self presentViewController:vc3 animated:YES completion:nil];
}];

Of course you have to use the correct storyboard name and the view controller's storyboard identifier that you should have set in the storyboard.

If you're using a navigation controller you can also push to the navigation controller which you could use:

[self.navigationController pushViewController:vc3 animated:YES];

instead of:

[self presentViewController:vc3 animated:YES completion:nil];
