Orientation implementation issue Storyboard

I use storyboard and have lot of viewcontroller. I'm facing issue on Orientation. I have tried different ways which has provided stackoverflow. But i did't get any answer. Is there any issue on Xcode 6.0 with ios 8?

My implementation process:

step 1:

I have added below code in Newscontroller.m

-(BOOL)shouldAutorotate {
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)self{
    return UIInterfaceOrientationMaskPortrait;
}

Now question is ... i need disable orientation specific view controllers like keep only portrait. Any one having idea?
