I have updated my app to IOS7 and now I have very strange issue.
When I start app it start to do what it suppose to do and after 3-5 minutes app stops to work.
But not completely. It stops to send notifications, track location etc.
And if I try to make some action I get this in console:

libc++abi.dylib: terminating with uncaught exception of type NSException
Any idea what is this?
App works fine in IOS6.
Create an exception breakpoint in Xcode that stops on all exceptions. Then the debugger will stop when that exception is raised. It looks like it is in
[UINib instantiateWithOwner:options:]
But I can't tell if you are calling that or the system.
See here for a related issue: Terminating app due to uncaught exception 'NSUnknownKeyException'
I must test this on real phone just to be sure.
I have a piece of code that refreshes some labels in the view every X seconds.
It works fine until IOS7. On IOS7 app crashes after 3 minutes and I get the error from the question.
Every time I refresh labels in the view I was opened a new connection to sqlite to get data.
In IOS7 I get error so I made one instance of data access class and init it only in viewDidLoad() and now it works fine.
If after test I confirm that I am right I will definitely make singleton pattern of my data access class.
