Hi,
I have created an App for IOS which makes a call to Integration Server (HTTP post), gets business data (in JSON), parse the data and put it into SQLite database.
Whenever I click on the button to download business data from Server, the app crashes. I managed to get the console output during crash.
Here it is:

I’m quite new for Mobile App development as well as for IOS. I read in some internet forums that the above errors are related to wrong Memory management. Either the app has a memory leak or uses more memory. I also found that there is something called Automatic Reference Counting (ARC) which inserts memory management code at compile time.
We write java code at the mobile designer side and upload the whole project to Mobile Administrator server. The questions I have are:
- How the java code is converted into Ojective-C or to a formate that runs in IOS? What all happens in between and how we can influence the compiler to use certain parameters?
- Do you have any suggestion on how the above application should be debugged further?
- Any help or article to analyse crash dump would be helpful.
Thanks in advance,
Siva
