Hey there,
I made an application with UE 4.10.4 and launched on my iPad Air with success, but this one crashed after the launch screen.
Now, how can I understand why my app crashes after that point?

Thanks.

Hey I.,

Please provide additional information about your project, the type of iOS device you’re on as well as the logs. You can learn how to obtain the logs from your iOS device by looking through the following [documentation][1].

Thanks!

Hi ,
well since I opened this thread, many things changed, but I still got some problems. Now I know how to obtain logs, but now that’s the situation:

If I click on LAUNCH from the UNREAL EDITOR: I got no errors, but the application crashes on my device just after the splash screen. With no logs!

If I export everything as a iOS project: I got an “Unknown Error” as fatal error, and in the Output Log, Unreal says this: “IPP ERROR: Application exception: System.IO.IOException: The file is too long. This operation is currently limited to supporting files less than 2 gigabytes in size.”
The same project was built succesfully before to set up properly all the various settings into the IOS section in Project Settings. That’s weird.

My project doesn’t not contain any particular and complicated meshes, just a couple of particles effect.

My device is an APPLE iPAD Air.
I attached the “output log” when I try to export my project as an iOS Project.[link text][1]

Could you please tell me whether or not the file size is less than 2GB?

Upload the logs from your iOS device that you’re receiving a crash on. Please follow the documentation link from my original post.

Thanks!

Sorry. I’m back, I was working on the Android version in the meantime, and I hadn’t access to the iPad.

I followed the documentation linked, and I attached the log here.[link text][1]

I uploaded a log, sorry.

Hey ,

Are those the only logs you were able to obtain? They seem to be cut off. Do you have any other logs that you could provide?

Thanks!

I am having the exact same problem, is there a fix? Please, this is becoming stressful as I am trying to get the app approved for a client. Thanks.
