ad hoc version exits immediately when try to load the app to memory
<p>I have an app, it worked well on simulator, but the ad hoc version always exit after Default.png launched and started to run on my ipod.</p>

<p>I try to check if there is any problem concerns</p>

<pre><code>•   Case sensitivity.  
•   Read/write bundle files.  
•   Memory Leak
</code></pre>

<p>But everything look likes Ok. The app occupies memory no more than 800K.
I set the breakpoints anywhere but it still exits before debugger reaches them.
No crash reported. </p>

<p><strong>There is an interest thing if I set 1 or more NSAlertView and show in viewDidLoad of rootController(UITabBarController), it will work correctly!</strong></p>

<p>It is my first time to use UITabBarController, I always construct my self's multi viewcontrollers.</p>

<p>I am not sure if this problem relates to the usage of UITabBarController. </p>

<p>My Xcode 3.1.4
os x is 10.6.5</p>

<p>I have sticked on for 3,4 days.</p>

<p>Welcome any comment</p>

<p>Thanks
