When I use [dic writeToFile:path atomically:YES]; I received a crash like this：

I think the NSDictionary contains more items ,failed when malloc memory.
How to write a large dictionary to file? or other best way?
So can someone help me please what I'm doing wrong?

can someone explain why these crashes keep occurring?
I don't think it makes sense to turn the NSDictionary into another NSDictionary with [NSDictionary dictionaryWithDictionary:] ... also NSDictionary can be non-nil but contain 0 key entries (an empty dictionary).
Perhaps you want: NSDictionary *apnsPayload = [userInfo objectForKey: #"alert"]; ?

I have check my code, no NSArray is used.It seems that the run loop was dispatch the touch event, and generate a NSArray, but I am not sure about it and what let to the crash.
You cannot insert nil into an NSArray, if you want to put a placeholder object into your array you can use [NSNull null]. The solution to your problem is to find the nil object that you're attempting to insert and refrain from inserting it, or alloc/init it and then insert.
If you post the rest of your code we may be able to pinpoint the problem more specifically.
I'm trying to analyze a log for what appears to be an intermittent crash.

Looking through the trace with the exception, I see a CF_forwarding_prep_0 message, which is followed by an [NSProxy doesNotRecognizeSelector] exception. Reading that, is it a safe assumption that the cause of the issue is that there's a pointer to a tableview delegate that isn't being set to nil? That's about the only discernible thing I see here.
Any help would be most appreciated. Thanks!
it shows error log as below, who can tell me how could I find the code where induce this crash? thanks.
my device is iphone IOS 5.0,thanks very much.

Go to breakpoints tab on xcode, in the bottom left hand corner there is a little plus button. Press it, click add exception breakpoint. Don't change any of the breakpoint settings and click done.
If you run your program again it should break on the line of code witch is crashing. As long as it is your code thats coursing this rather then an incorrect outlet in IB.
Hope this helps

For some reason, the files were missing. I reinstalled Xcode from the AppStore and it started working again.
I have no idea how the files were missing.
