iOS: Background image navigation bar mail compose view controller

Since iOS 5 it is easy to customize the background image of UINavigationBar, but it seems that there is something that I am missing when it comes to setting the background image for MFMailComposeViewController. I use the following snippet to set up an instance of MFMailComposeViewController.

if ([MFMailComposeViewController canSendMail])) {
    // Initialization
    MFMailComposeViewController *vc = [[MFMailComposeViewController alloc] init];
    [vc setModalPresentationStyle:UIModalPresentationFormSheet];

    // Navigation Bar
    [[vc navigationBar] setBackgroundImage:[UIImage imageNamed:@"navbar_top"] forBarMetrics:UIBarMetricsDefault];

    // Configuration
    [vc setMailComposeDelegate:self];

    // Present Mail Compose View Controller
    [self presentViewController:vc animated:YES completion:nil];
}

While the bar button items are properly skinned, the navigation bar of the mail compose view controller is not. Am I overlooking something?

Just add some code in your "myAppDelegate.m" as follows:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    ...
    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"blueBarBG.png"] forBarMetrics:UIBarMetricsDefault];
    ...
}

Hope it will help you

after u present the controller

// Present Mail Compose View Controller
[self presentViewController:vc animated:YES completion:nil];

add the image as an imageView like this

UIImage *image = [UIImage imageNamed: @"navbar_top.png"];
UIImageView * iv = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,42)];
iv.image = image;
iv.contentMode = UIViewContentModeCenter;
[[[vc viewControllers] lastObject] navigationItem].titleView = iv;
[[vc navigationBar] sendSubviewToBack:iv];
[iv release];

but I believe there is some kind of protection that came with iOS4.

It is clearly stated here that you MUST NOT change the interface provided by Apple.

http://developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMailComposeViewController_class/Reference/Reference.html

Important: The mail composition interface itself is not customizable and must not be modified by your application. In addition, after presenting the interface, your application is not allowed to make further changes to the email content. The user may still edit the content using the interface, but programmatic changes are ignored. Thus, you must set the values of content fields before presenting the interface.

i have searched the forums and some have got their app rejected, so i guess u should refrain urself from doing this.

hope it helps. happy coding :)

You can do this because MFMailComposeViewController class inherited from 

UINavigationController : UIViewController : UIResponder : NSObject

But go through the apple documentation. Apple wont allow to do so.

EDIT : refer custom-background-for-uinavigationbar link.

I think u might have given wrong image name: navbar_top it might be navbar_top.png or navbar_top.jpg

U can try this:

if([[UINavigationBar class] respondsToSelector:@selector(appearance)]) //iOS >=5.0
{
  [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navbar_top.png"] forBarMetrics:UIBarMetricsDefault];
}
