How can I load the UIView in my code programatically?

Thanks.

FlipView Approach to load UIView Programmatically

In .h file use this code

  @interface MainViewController : UIViewController {
    IBOutlet UIView *secondaryView;
}
- (IBAction)toggleView:(id)sender; //Action for toggle view
- (IBAction)returnView:(id)sender;


@end

In .m

- (IBAction)toggleView:(id)sender {
        [UIView beginAnimations:nil context:nil];
        [UIView setAnimationDuration:1.0];
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
                               forView:[self view]
                                 cache:YES];
        [[self view] addSubview:secondaryView];
        [UIView commitAnimations];
    }

    //Flips to front when "Done" is pressed
    - (IBAction)returnView:(id)sender {
        [UIView beginAnimations:nil context:nil];
        [UIView setAnimationDuration:1.0];
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
                               forView:[self view]
                                 cache:YES];
        [secondaryView removeFromSuperview];
        [UIView commitAnimations];
    }
