更改UIPrintInteractionController导航栏标题

Question

如何更改UIPrintInteractionController的导航栏标题（打印机选项）？

Answer 1

您可以使用UIPrintInteractionController的委托方法来更改它的外观，

- (UIViewController *)printInteractionControllerParentViewController:   (UIPrintInteractionController *)printInteractionController
{
    return self.navigationController;
}
- (void)printInteractionControllerDidPresentPrinterOptions:(UIPrintInteractionController *)printInteractionController
{
    // self.navigationController.topViewController.navigationController.navigationBar.tintColor=[UIColor redColor];
    self.navigationController.navigationBar.tintColor = [UIColor greenColor];

   // self.navigationController.topViewController.navigationController.navigationBar.barTintColor=[UIColor purpleColor];
   self.navigationController.topViewController.navigationController.navigationBar.tintColor=[UIColor yellowColor];
}

 [[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
    self.navigationController.navigationBar.barTintColor = AppColor;
    self.navigationController.topViewController.navigationController.navigationBar.tintColor=[UIColor whiteColor];

 [[UINavigationBar appearance] setTitleTextAttributes:
