Crash without warning xcode

Question

I am developing the application for over 6 month. After everithing was developed and tested, I put app aside for 2 weeks and now when I run it it start crashing without any warning:

Even if I hit Continue Execution over 20 times still nothing in log.

I have all exceptions break point and malloc_errer_break set.

App crash when I move from screen to screen (When I open 2 screen or when I close it).

Answer 1

Let me guess - you need to change a property to strong (from weak). Name of that problematic property you will find in the console after enabling check for zombies (press ⌘⇧< then check Enable Zombie Objects in Diagnostics/Memory Management)

Answer 2

Most of the time EXC_BAD_ACCESS happens when you use an object that no longer exists.

You could check for Zombies during run-time to see if you use any of your object which doesn't exist anymore.

Answer 3

This a very generic error, I suggest to review your code and try again and as Anc Ainu said the reason is of using an object thats no longer exists.

Answer 4

1. I recommend to set up Exception breakpoint to get place from which your app crashes. To make this breakpoint enabled go to breakpoint tab, then tap on plus button and choose 'Add Exception Breakpoint'.

2. And yes, enabling NSZombies also could help you.
