Answer 1

if you use segue between 2 controllers you must overload prepareToSegue method

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// check if it's the good segue with the identifier
if([[segue identifier] isEqualToString:@"blablabla"])
{
    // permit you to get the destination segue
    [segue destinationViewController];
    // then you can set what you want in your destination controller
}
}
