All of my view has a blue navigation bar but when I want user to choose a photo, the UIImagePicker is black. I tried to set the navigation bar of UIImagePickerController to blue using UIBarStyleDefault but it does not work for me, the color is still black. I tried with other UIBarStyle like UIBarStyleBlack and UIBarStyleOpaque as well but it doesn't change the navigation bar of the picker anyway. Here is my code

    // Let the user choose a new photo.
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    imagePicker.navigationBar.barStyle = UIBarStyleDefault;
    [self presentModalViewController:imagePicker animated:YES];
    [imagePicker release];
