How to Set the "tintColor" of the Back Button for Popovers in iOS5

I am developing an iPad application. After customizing the popover background by setting it red, I tried to set the "tintColor" of the "Back" button on the popover navigation bar. Otherwise, it looks ugly!

As I am developing the application in iOS5, the new appearance protocol makes customization very easy:


- (void)customizeAppearance
{
    // set the back button tint color
    [[UIBarButtonItem appearance] setTintColor: [UIColor redColor]];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    DBG_CALLED

    

    [self customizeAppearance];

    return YES;

}

Note that DBG_CALLED is my debug macro. However, in this case the update is global and the buttons on the toolbar are updated also which is not what I want!

The solution is specifying where to update the bar button items:

- (void)customizeAppearance

{

    // set the back button tint color for the popovers

    [[UIBarButtonItem appearanceWhenContainedIn:[UIPopoverController class], nil] 

                                   setTintColor:[UIColor redColor]];

}

The end result is what I want exactly:

I love the iOS5!
