iOS 8.3 : Why is the navigation bar background color for MFMailComposeViewController still white?

Question

Seems for iOS 8.3 the navigation bar background color for MFMailComposeViewController is white no matter what I do. How do I change the background color properly? Here is the code I am using. Simple and straight forward.

    MFMailComposeViewController* myMailViewController = [[MFMailComposeViewController alloc] init];
    myMailViewController.mailComposeDelegate = self;
    [myMailViewController.navigationBar setBackgroundColor:[UIColor orangeColor]];
    [self presentViewController:myMailViewController animated:YES completion:nil];

I tried many other alternatives such as changing the tint of the navigation bar, but I am getting the same result. Is this a bug? Any suggestions or tips is appreciated.

Answer 1

[UINavigationBar appearance].barTintColor = [UIColor yourColor];

应该在MFMailComposer实例化之前调用它。
