supportedInterfaceOrientations returns an NSUInteger. It returns all of the interface orientations that the view controller supports, a mask of interface orientation values.

You need to return values defined in UIInterfaceOrientationMask Enum, like the following shows:

}

- (NSUInteger)supportedInterfaceOrientations {
    return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}
