crash report and rejected by Apple
<p>Hello everyone
<a href="http://stackoverflow.com/editing-help">http://stackoverflow.com/editing-help</a>
I have developed one app for my customer.
I tested it on devices(ipad/ipod touch) with ios 4.2, 4.3.2 3.1.3 under ios deployment target 3.0, 3.1.3, 4.2 
Every case worked well, I sent my customer the source code project.
They compiled on their mac and submitted to app store.
But Apple rejected the app with crash report</p>

<p>I try to duplicate the crash on my device(ipad/ipod touch) but no result.
I just wonder if there is any difference between my mac and my customer's mac causes the error happened.</p>

<p><strong>Update:</strong>
after got the suggestion from here, I dragged the crash log to Organizer and got the translated result:</p>

<p>The crash happened at thread0, step 35, mem address 0x00002c60 
So I called command atos to locate the crash point as below:</p>

<pre><code>atos -arch armv6 -o MyAppName.app/MyAppName 0x00002c60
</code></pre>

<p>it returns</p>

<pre><code>-[AppDelegate setGPictureArray1:] (in MyAppName) (AppDelegate.m:9)
</code></pre>

<p>I show all codes before the line</p>

<pre><code>//AppDelegate.h
#import &lt;UIKit/UIKit.h&gt;
#import "RootViewController.h"
@class RootViewController;
@interface AppDelegate : NSObject &lt;UIApplicationDelegate&gt; {
    UIWindow *window;
    IBOutlet RootViewController *rootViewController;
    NSMutableArray * gPictureArray1; 
    NSMutableArray * gPictureArray2; 

}

@property (nonatomic, retain) NSMutableArray * gPictureArray1;
@property (nonatomic, retain) NSMutableArray * gPictureArray2;
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) RootViewController *rootViewController;
@end

 //AppDelegate.m

#import "AppDelegate.h"
#import "RootViewController.h"
@implementation AppDelegate

@synthesize window;
@synthesize rootViewController;
@synthesize gPictureArray1;//**it looks like the crash happens here**
@synthesize gPictureArray2;
