将嵌套在容器视图控制器中的 UINavigationController 添加到 UITabBarController

问题描述

我有一个 UIViewController(红色)设置为 UITabBarController 的第一个选项卡，如下面的故事板所示.这个视图控制器是一个容器视图控制器，并在它的 contentView(红色视图控制器内的白色矩形)内加载了一个 UINavigationController.

I have a UIViewController (red) set as the first tab of a UITabBarController as shown in the storyboard below. This view controller is a container view controller and loads a UINavigationController inside its contentView (the white rectangle inside the red view controller).

这是我在红色视图控制器的 contentView 中加载导航控制器的代码:

This is my code for loading the navigation controller inside the red view controller's contentView:

- (void)viewDidLoad
{
    [super viewDidLoad];

    // instantiate navigation controller
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UINavigationController *navigationVC = [storyboard instantiateViewControllerWithIdentifier:@"N"];

    // place navigation controller inside content view
    [self addChildViewController:navigationVC];
    navigationVC.view.frame = self.containerView.bounds;
    [self.containerView addSubview:navigationVC.view];
    [navigationVC didMoveToParentViewController:self];
}

根据我对视图控制器包含的了解，这应该工作，因为我明确设置导航控制器的框架.但是，当 tableView 中有足够的单元格超过容器的高度时，当我向下滚动时，tableView 的末尾总会有一个栏.我已将 tableView 的 backgroundColor 设置为 orange 并将单元格的 backgroundColor 设置为 white 为了看到差异.

From what I know about view controller containment this should work as I am explicitly setting the frame for the navigation controller. However, when there are enough cells in the tableView to exceed the container's height there is always a bar at the end of the tableView when I scroll down. I have set the tableView's backgroundColor to orange and the cell's backgroundColor to white in order to see the difference.

如何消除 tableView 末尾的橙色间隙?

How do I get rid of that orange gap at the end of the tableView?

(注意:我不使用自动布局，我需要一个同时适用于 iOS7 和 iOS6的解决方案.)

(Note: I am not using autolayout and I need a solution that works for both - iOS7 and iOS6.)

推荐答案

我知道您也在寻找适用于 iOS 6 的答案，但在 iOS 7 及更高版本上您可以使用

I know you are also looking for an answer which works on iOS 6, but on iOS 7 and above you can use

self.extendedLayoutIncludesOpaqueBars = YES;
