Answer 1

You won't be able to open like a popup a UIViewController.
For that you will have to use a simple UIView
Add the UIview (popup shape like) to your current view.
- (void) initPopUpView {
popup.alpha = 0;
popup.frame = CGRectMake (160, 240, 0, 0);
[self.view addSubview:popup];
}
- (void) animatePopUpShow {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[UIView setAnimationDelegate:self];
[UIView setAnimationWillStartSelector:#selector(initPopUpView)];
popup.alpha = 1;
popup.frame = CGRectMake (20, 40, 300, 400);
[UIView commitAnimations];
}

(void)popup
{
UIView *AView1=[[UIView alloc] initWithFrame:CGRectMake(self.view.frame.size.width/2,self.view.frame.size.height/2, 0, 0)];
[AView1 setBackgroundColor:[UIColor redColor]];
[UIView animateWithDuration:2.5 animations:^{AView1.frame = CGRectMake(35, 10, self.view.frame.size.width-70, self.view.frame.size.height-100);}];
