objective c - App crash only on iPhone Device and not in Simulator

Question

In my app, when I press a button the method called for that button first assigns my textfield texts directly to NSArray object like:

 val = [[NSArray alloc] initWithObjects: nameText.text, cellText.text, p_emText.text, 
                                      p_cnfrmText.text, s_emText.text, s_cnfrmText.text,
                                      emailText.text, ecnfrmText.text, lat, longt,  
                                      nil];

when I run my app on simulator no app crashing occurs, but when I run it on my iPhone device it gives: Thread 1: program recieved signal "EXC_BAC_ACCESS"

Can anybody tell why this happens and what's the solution for this scenario?

Answer 1

In XCode, go to menu "edit scheme", choose the running configuration and add 'NSZombieEnabled' like in the picture below, when your apps crashes, it will provide you additional infos on the crash that should help you debug it.

EDIT

Note that when your application debug is over, remove the NSZombieEnabled command as it impacts the application performances
