This is in my UIviewcontroller image
In simulator its showing like this.

Answer 1

Try changing your simulator to 3.5 Inch, because from what I see you haven't add autolayout to your Views to support 4 Inch.

Answer 2

Most probably the registration controls (UILabel and UItextviews) are added on self.view instead on the view that is of half screen size.

Answer 3

You could go for the code below:
-(void)viewDidLoad
{
backgroundButton = [[UIButton alloc] initWithFrame:CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)]; //Background button to handle tap outside popup view
[backgroundButton addTarget:self action:#selector(tapDetected) forControlEvents:UIControlEventTouchUpInside];
}
-(void)tapDetected /* When user tap outside popup view so as to dismiss the view*/
{
[backgroundButton removeFromSuperview];
[tempView removeFromSuperview];
}
-(void)buttonClicked:(UIButton *)sender /*To create and open popup view */
{
[self.view addSubview:backgroundButton];
tempView = [[UIView alloc] initWithFrame:CGRectMake(15, 100, 300, 300)]; //PopUp View
[tempView setBackgroundColor:[UIColor redColor]];
[backgroundButton addSubview:tempView];
[tempView setAlpha:1];
}
