UIImagePickerController 的 pushViewController 把推视图放在导航栏后面

问题描述

当我将视图控制器推入 UIImagePickerController 对象时，视图控制器的视图错位在导航栏后面.无论我选择什么作为图像选择器源.我以模态方式呈现图像选择器并在其委托中执行以下操作

When I push a view controller into UIImagePickerController object, the view controller's view is misplaced behind the navigation bar. no matter what I choose as image picker source. I present image picker modally and do the following in its delegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  [[UIApplication sharedApplication] setStatusBarHidden:NO];
  [picker setNavigationBarHidden:NO];

  SecondViewController *secondVC = [[SecondViewController alloc] init];
  [picker pushViewController:secondVC animated:YES];
  [secondVC release];
}

并且在 SecondViewController 中没有做任何特别的事情.

and in SecondViewController's doing nothing special.

当我将同一个视图控制器推入 UINavigationController 的对象时，它被正确放置在导航栏下方.要使用图像选择器作为导航控制器，我还应该做什么?

When I pushed the same view controller into UINavigationController's object, it is placed correctly beneath the navigation bar.What should I do additionally to use image picker as navigation controller?

推荐答案

我应该设置图像选择器的导航栏的 translucent 在推送第二个视图控制器之前没有属性.

I should have set image picker's navigation bar's translucent property NO before push second view controller.
