回答1:

If you want all of our navigation controllers to respect the top view controller you can use a category so you don't have to go through and change a bunch of class names.

 @implementation UINavigationController (Rotation_IOS6)

-(BOOL)shouldAutorotate
{
   return [[self.viewControllers lastObject] shouldAutorotate];
 } 

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject]     preferredInterfaceOrientationForPresentation];
}

@end

As a few of the comments point to, this is a quick fix to the problem. A better solution is subclass UINavigationController and put these methods there. A subclass also helps for supporting 6 and 7.

Try this:

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

i find solution the think which i do is. step one override my UInavigationcontroller by creating a category

step two Replace [self.window addSubview:[navigationController view]]; //OLD

With [self.window setRootViewController:navigationController]; //NEW

回答5:

use this in your Appdelegate.m

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    NSLog(@"Interface orientations");
    if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPad ){

        return UIInterfaceOrientationMaskLandScape;
    }
    else{
        return UIInterfaceOrientationMaskPortrait;
    }
}

It helped me..
