iphone app hangs in AppDelegate (?)
<p>No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller.  In fact, control passes out of the last "}" in applicationDidFinishLaunching.  But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there).  The last line is, UIApplication _performInitializationWithURL:sourceBundleID:].  I missed a step? I executed a step improperly? </p>
