Default.png shows, but not for long
<p>LOTS of Default.png Q's, but I didn't read one like this: I see Default.png, but then the screen goes blank, but no error messages, no abort.  What am I missing?</p>

<p>SDK 4.3, iPhone only, no nib, no schemes, no orientation other than portrait up/down.  Nav controller, 4 tabs.  </p>

<p>App ABC works fine. </p>

<p>Clone XYZ doesn’t.  </p>

<p>info.plist seems identical, including the half dozen icon files; neither app has an entry that contains “MainWindow.”  Analyze and both generate “Build succeeded.”  Run and both display “Attaching to process blah-blah-blah.”  Any combo of reboot and/or restart Mac/XCode/simulator/device doesn’t do a dang thing. There is one difference, though: the drop-down for ABC shows the full device name, two 4.2’s and two 4.3’s; XYZ shows only “IOS Device” and the two 4.3’s.   ABC shows all the NSLogs.  XYZ shows none of them.  And in both cases, the first NSLog is right after</p>

<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
</code></pre>

<p>Clean all targets made no difference. I’m thinking, “Clone NOT.”</p>

<hr>

<p>XJones, here's the code you requested. I've whacked it down as much as I could.</p>

<p>After the above, all the usual labels and text fields follow.</p>

<p>Thanks again for taking the time to slog through it.</p>

<p>I've got my hopes set on a "Duh!"</p>
