ios - 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(delegate)方法来改变它的外观，

- (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];
}
