Answer 1

If you want to run your entire app in portrait mode only you can change these settings on your target. Just use the check boxes to select which orientations you would like to support.

You can set the following method.

#define IS_IPHONE                               (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

#define SCREEN_WIDTH                            ([[UIScreen mainScreen] bounds].size.width)
#define SCREEN_HEIGHT                           ([[UIScreen mainScreen] bounds].size.height)
#define SCREEN_MAX_LENGTH                       (MAX(SCREEN_WIDTH, SCREEN_HEIGHT))
#define SCREEN_MIN_LENGTH                       (MIN(SCREEN_WIDTH, SCREEN_HEIGHT))

#define IPHONE4                                 (IS_IPHONE && SCREEN_MAX_LENGTH < 568.0)
#define IPHONE5                                 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)
#define IPHONE6                                 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)
#define IPHONE6PLUS                             (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)



-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
        if (IPHONE6 || IPHONE6PLUS) {
            return (interfaceOrientation == UIInterfaceOrientationPortrait);
        }
        return nil;
    }

Or you can use the one more method

- (BOOL)shouldAutorotate {
    return NO;
}
