Im developing my app and yesterday while I was playing with it crashed. I wasnt debugging, so I thought I'd take a look at the crash log today.
But my surprise is that I can't see anything that can give me some info, here it is:

Hope you can help me with this, thanks.
Without the app still in memory I'm not sure there's much you can do. From experience I guess you messaged an object that has been dealloc'd. (Maybe the datasource object for your MKMapView?) I'd try running your app with zombies enabled to track it down.

I have an App that works perfectly on Debug (device and simulator) but once I archive it for AdHoc it just crashes.
Even with the Distribution provision files selected y clic play and works fine.
Now if I make an .ipa through AdHoc... it loads and crashes... 1seg... not even open.
I guess maybe something is wrong, but how on earth I can find the bug if there's any? I don't have any log message and it's a big big App.
Any idea?
Thanks.
By the way, this is what I get:

I have not been able to reproduce this particular crash myself but it has been reported via our crash reporting tool and is being experienced by several hundred of our users. Finding it hard to debug or reproduce.
It happens on all hardware platforms but only on iOS 6. Any help or insights will be highly appreciated.

Try setting the delegate method of the locationManager to nil in the dealloc method of the class you are using it in
Something like this:
-(void) dealloc
{
self.locationManager.delegate = nil;
}
What might be happening is that the object is being deallocated (maybe due to low memory) and the location manager is trying to send a message to a non existing delegate.
I have a random-looking crash related to UIKit and I can't seem to figure out what is wrong.
Does anyone see a familiar pattern here or do you think this might be a random OS-related crash? Is there a way to find out which Buttons or UI-elements were involved here?

Are you familiar with the concept of a stack trace? What you are looking at are the lines of code execution from the crash (0) back to a recent frame entry. As such, this is referred to as a 'back trace' since it goes backwards from the point that the code stopped executing.
I have no knowledge of your code, but you can see from line 14 of the back trace that you received a low memory warning. This warning caused a chain of unload events, including a deallocation of a UITableView (line 3).
This is immediately followed by the _sigtramp, which probably indicates an EXC_BAD_ACCESS. My guess, without seeing the rest of your code, is that you are accessing something that has been released by the low memory unload situation.
I have a strange problem with my app, sometimes, very rare in fact, when run on iPhone4, it crashes right at the beginning, I got the crash log, but I really can't make anything of it. I'm kind of stuck, where should I look? Here is the log:

I was not able to find any pattern for the crash, it simply happens like maybe once in 30-40 app start-ups. What beats me, beside the fact that I don't know how the interpret the crash log, is why this happens so rare, with no apparent reason?
You need to symbolicate that crash log before you can see exactly which part of your code is crashing.
