UIAppearence Support for IOS 6 - unexpected results - objective-c

Question

Below code is perfectly working fine iOS 5, but not on iOS 6 or above.
What I want that for Email composer sheet the navigationBar image will be different then other UINavigationBar classes. I can't understand that debug pointer is responding the appearance method but on device it shows navigationBar image as "bgNavigationBar.png"; expected is "bgNavigationBar_2.png".
Please guide me.......
if ([[UINavigationBar class]respondsToSelector:#selector(appearance)]) {
UIImage *logoImage44 = [[UIImage imageNamed:#"bgNavigationBar.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage:logoImage44 forBarMetrics:UIBarMetricsDefault];
UIImage *ImagePlain = [[UIImage imageNamed:#"bgNavigationBar_2.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearanceWhenContainedIn:[MFMailComposeViewController class], nil] setBackgroundImage:ImagePlain forBarMetrics:UIBarMetricsDefault];
}

This thing is not working in ios6.
[[UINavigationBar appearanceWhenContainedIn:[MFMessageComposeViewController class], nil] setBackgroundImage:[UIImage imageNamed:#"bgNavigationBar_2.png"] forBarMetrics:UIBarMetricsDefault];
Just you need to set this property in your Mail Handler Class.
if (![[UINavigationBar class]respondsToSelector:#selector(appearance)])
{
UIView *backgroundView = [[[UIView alloc] initWithFrame:CGRectMake(0,0,320,44)]autorelease];
[backgroundView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"bgNavigationBar_2.png"]]];
controller.topViewController.navigationItem.titleView = backgroundView ;
}
else
{
UIImage *gradientImagePlain = [[UIImage imageNamed:#"bgNavigationBar_2.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage:gradientImagePlain forBarMetrics:UIBarMetricsDefault];
}
and then reset another image for all other navigation controller's background image.
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self.parentController dismissModalViewControllerAnimated:YES];
UIImage *gradientImagePlain = [[UIImage imageNamed:#"bgNavigationBar.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage:gradientImagePlain forBarMetrics:UIBarMetricsDefault];
}
Hope this will work for you.
