Answer 1

you can use the method animate view upward to move the view upward and can move the view downward using the methods below :

    -(void)animateViewUpward
     {
       [UIView beginAnimations: @"upView" context: nil];
       [UIView setAnimationDelegate: self];
       [UIView setAnimationDuration: 0.4];
       [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
       self.view.frame = CGRectMake(0,-110, 320,460);
       [UIView commitAnimations];
     }

   -(void)animateViewDownward
    {
       [UIView beginAnimations: @"downView" context: nil];
       [UIView setAnimationDelegate: self];
       [UIView setAnimationDuration: 0.4];
       [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
       self.view.frame = CGRectMake(0,0, 320,460);
       [UIView commitAnimations];
   }
