调整 UITabBarController 中视图的大小，使其不出现在选项卡栏后面

我设置了一个应用程序，其中窗口包含一个选项卡栏控制器，其中一个选项卡加载一个名为“ShowCaseView.xib”的 NIB；该文件由自定义 ShowcaseViewController 类拥有。

在 ShowcaseViewcontroller 类中，我添加了一个 UIScrollView 对象，如下所示：

imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]];
[[self view] addSubview:imageScrollView];

我遇到的问题是这个 UIScrollView 对象扩展了 < em>在我的标签栏控制器下面。

所以我不得不手动减少它的插入：

#define TAB_BAR_HEIGHT 48
.
.
UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0);    
[imageScrollView setScrollIndicatorInsets:edgeInsets];

那么，

通常需要从视图中手动扣除标签栏高度（无论是通过减少子视图的大小还是检查器中的视图NIB）？
有没有一种方法可以告诉从选项卡栏加载的 NIB 视图自动调整自身大小，而不是位于选项卡栏后面？

I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib'; this file is owned by a custom ShowcaseViewController class.

In the ShowcaseViewcontroller class I have added a UIScrollView object, like so:

imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]];
[[self view] addSubview:imageScrollView];

The issue I am having is that this UIScrollView object extends beneath my tab bar controller.

So I have had to reduce its insets manually:

#define TAB_BAR_HEIGHT 48
.
.
UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0);    
[imageScrollView setScrollIndicatorInsets:edgeInsets];

So,

Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)?
Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar?
