Question

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?

Answer 1

In the NIB file is the “Size & Position” for the view set to “Frame”? I should be Layout.
