Answer 1

You just need to set size inspector attributes like this:
P.S. Edit 1:You have to return yes in
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
Edit 2:
If you are doing like this you don't need if condition for checking orientation and make frame for it.
