My app is rejected from the iOS store because the app is terminated after user log in. I'm not able to reproduce the problem (local devices, TestFlight), it looks like it only happens when the app is running in production.
I have symbolicated the crash report that I got from the App Store review team. I understand that a abort() is called ontThread 0. But I have a hard time understanding the crash report. I'm new to crash reports so I appreciate the help!

I am facing a crash with the following log. Basically I am trying to add an Image to a web view through camera.
The flow is as follows:
1. I take a picture through camera using Image Picker controller, save it into PhotosAlbum and get the image data.
2. Then I upload that image to the server, get the related data to that image.
3. Then I call a JS function to insert the URL received of the image in the web view.
After repeating the steps 1-3 for a couple of times, I get a crash on this particular thread.

We use WKWebView to show some web page. And using WKUserContentController as bridge to do some call between H5 and Native.
So, how to debug this kind of crash?
I tried to read the source code of Webkit, but it is useless. I only figure out that the WebKit network process is about to exit when crash happened.
We tried to reload webview when WKKit process crashed, and the crash is gone。
- (void)webViewWebContentProcessDidTerminate:(WKWebView *)webView {
[_webView reload];
}
my app crash in IMGSGX543GLDriver ,the most difficult is there are not any code of my app in the crash log and i cannot reproduce it .This issue cost me several days and I still have no idea. Any ideas you guys provide, I will try. Thank you for your help.

Recently, I upgradie my iPad app's code to support iOS 4.0. I just added the following methods with no actual code in them in my AppDelegate:
applicationWillEnterForeground:
applicationDidBecomeActive:
applicationWillResignActive:
applicationDidEnterBackground:
I imagined there shouldn't be any change on my 3.2 device, as it shouldn't even be aware of these methods.
However, I received the following "failed to resume in time" time out, on my 3.2 device, which shouldn't do any resuming. This just doesn't make sense to me. Any ideas?
