Using UIDevice - setOrientation will make app rejected?

Question

To force portrait, I need to use the following snippet and I wish to learn if by using it, will make the app get rejected from appstore approval?

[[UIDevice currentDevice] performSelector:NSSelectorFromString(@"setOrientation:")

Answer 1

Why don't you just use this method? In your AppDelegate.m:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{

        return UIInterfaceOrientationMaskPortrait;
}

It forces the portrait orientation and much safer then anything else. I used it in one of my apps and it was approved by Apple.
