UIAppearence Support for IOS 6

Add navigationbar image for MFMessageComposeViewController class.  For the ios5 below code is working fine.

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];
}

But same code is not working for ios6. So i have given the solution for it.

This is working not working in iOS 6.

[[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];
}
