Update :
Apple message:
We found your app crashed on launch so we were unable to review it. Please revise your app and test it on a device to ensure it will launch without crashing, and that it runs as expected, before resubmitting.
I posted full report (without binary image)

Answer 1

You submitted an application without symbols, so Apple couldn't tell you where in your application the fault is. The last bit of your code that is called gets called from
[UITableView _createPreparedCellForGlobalRow:withIndexPath:]
so it will happen in some delegate method of yours where you are preparing a cell, and you are sending a message to some object that doesn't understand it. There's probably more information in their report which you should post. Knowing which method was sent to which kind of object would be very helpful.
Meanwhile, turn on all warnings in your compiler that you can reasonably turn on and fix the problems, then run the static analyser and fix all problems that it finds, then let someone else test your application on a real device, in case you subconsciously avoid problem areas.

Answer 2

Here's what you need to do:
1) You need your archived application, the one you submitted. If not, then disregard the rest of the steps; it's game over.
2) The archive file is a bundle. You must show its contents.
3) Inside you will find a folder marked 'dSYMs.' Inside it you will find a file named <your app name>.app.dSYM. Select it and copy (using Copy/Command-C).
4) Go back one level. Inside the Products/Applications folder you will find your application. It's a bundle as well. You must show its contents.
5) Inside you will find your application's executable file. Now paste the dSYM file you had previously copied here.
6) Fire up your Terminal. cd to the Products/Applications folder in which you just pasted the dSYM file.
7) Now go back to that 'cryptic' report that Apple sent you. I see that you've included more information from the report, but there ought to be a section that shows all the processes that were running on your device at the time, and at the top should be your application. There are two large hexadecimal numbers there. Make a note of the first one. Then go to line 11 in your stack trace. Make a note of that long hexadecimal (0x000000010007435c). You'll need both of these numbers for the next step.
8) On your Terminal's command line enter
atos -o <your application name, including the extension> -l <first hex number> <second hex number>
9) atos should show you something like this:
-[classname method] (in <your app name>) (<file name where your object is located>:<line number>)
Now you'll have the clue you need to go after your problem.
Good luck to you in your endeavors.
