Without any details (like a completely symbolicated crash log and the corresponding code) this is like looking into a crystal ball: we have to guess.
From the crash log I'd say you create an array (via [NSArray arrayWithObjects:]) and feed it something that is not an Objective-C object. Maybe you forgot to add nil as the last object in the list? It's necessary so Objective-C knows where your list of objects ends.

DarkDustarrayWithObjects: takes a nil terminated list of object ids. You might have forget the nil
myArray = [NSArray arrayWithObjects:aDate, aValue, aString, nil];
Check reference

Sylvain G.You are getting EXC_BAD_ACCESS that means you are trying to reach a released object. Best practice is to put some break points and go step by step. I also recommend you to turn the zombies on. Product->Edit Scheme->Diagnostics and check Enable Zombie Objects.
after you do this when you crash you can see the point you crash and which method is trying to reach the released object.

omarmarisThe crash log gives you some information, which is not much, but better than nothing if you are not able to reproduce the crash yourself.
As you can see from these lines:
4 CoreFoundation 0x00027ef4 +[NSArray arrayWithObjects:] + 356
5 - 0x00033fcc 0x1000 + 208844
6 - 0x00033f46 0x1000 + 208710
7 UIKit 0x0022fb26 -[UISearchDisplayController searchBar:textDidChange:] + 78
the crash happens after a change in your searchBar, which triggers the corresponding action in your code. The action then tries to create an array and it crashes.
So, I would start checking the action that you associated to the search bar and see what happens there. You could also post it here, so that we can have a look.
