    <p>I really can't figure this out. When I click a link to open Safari from within my app, browse through the webpage, then return to my app, I can open and browse two <code>tabBarItems</code> in my <code>UITabBar</code>. But, when I try to select the one <code>atIndex: 0</code>, I get an <code>EXEC_BAD_ACCESS</code> and the following :(. Can anyone help me figure out how to make this not happen? I currently don't have any code that executes in <code>will</code> or <code>didEnterBackground</code> or <code>Foreground</code>. None. So the problem must be in the <code>UIViewController</code> for the first tab. (Oh and I don't know why it's adding a subview. Related?). Thoughts?</p> <pre><code>Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x0109ba63 objc_msgSend + 23 1 UIKit 0x0031f3df -[UIView(Internal) _didMoveFromWindow:toWindow:] + 966 2 UIKit 0x0031f1b0 -[UIView(Internal) _didMoveFromWindow:toWindow:] + 407 3 UIKit 0x0031f1b0 -[UIView(Internal) _didMoveFromWindow:toWindow:] + 407 4 UIKit 0x0031f1b0 -[UIView(Internal) _didMoveFromWindow:toWindow:] + 407 5 UIKit 0x0031f1b0 -[UIView(Internal) _didMoveFromWindow:toWindow:] + 407 6 UIKit 0x0031f1b0 -[UIView(Internal) _didMoveFromWindow:toWindow:] + 407 7 UIKit 0x0031dfc4 -[UIView(Hierarchy) _postMovedFromSuperview:] + 166 8 UIKit 0x00316dfc -[UIView(Internal) _addSubview:positioned:relativeTo:] + 1080 9 UIKit 0x0031514f -[UIView(Hierarchy) addSubview:] + 57 10 UIKit 0x003725ac -[UITransitionView transition:fromView:toView:] + 563 11 UIKit 0x00371955 -[UITransitionView transition:toView:] + 129 12 UIKit 0x003a6383 -[UITabBarController transitionFromViewController:toViewController:transition:shouldSetSelected:] + 459 13 UIKit 0x003a4d86 -[UITabBarController transitionFromViewController:toViewController:] + 64 14 UIKit 0x003a6b7e -[UITabBarController _setSelectedViewController:] + 263 15 UIKit 0x003a69ed -[UITabBarController _tabBarItemClicked:] + 352` </code></pre>

    1. COdoes it call viewDidLoad in your crashing view controller when the app returns back from bg?

    2. COYep. And two of the three tabs are fine. But I think @rcw3 is correct. It's a memory issue for sure (I have a 1030 x 450 px image loaded that I haven't touched in terms of memory yet). What's the best way to deal with it? Should I reinit the image once it loads again? Or every time ViewDidLoad? I'm struggling with that since it's the cause of this BAD_ACCESS. Thanks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
