App crashes on iPod

Question

I have created one application for iPhone. Application does a search for all watersports around the world. It is webservice based application.

My application runs smooth on Simulator without any crash report but when I create ipa file and launch same application on my iPod (I dont have my own iPhone) the application crashes after some time. Scenario of crash is not fixed so I assume this is because of Memory Leak or memory warning.

I used this function didReceiveMemoryWarning to identify memory warning but the function doesn't get called on simulator.

My Xcode version is 4.3 and unfortunately I updated the version of my iPod to iOS 6.0 so I can not test the app by connecting my iPod to the Mac. I am going to update my Mac and Xcode very soon but not soon enough to make this issue resolve/test.

Any ideas?

Answer 1

You can get the crash log from device using the following approaches. Check how-to-find-crash-logs or get-crash-reports-logs-from-iphone-ipad. You can symbolicate the crash log to find out the root cause. Check this question here for more details on that part Symbolicating iPhone App Crash Reports. Once you got the issue, you should be able to fix it.

Answer 2

Try this, put a temporary label then modify it when the didRecieveMemoryWarning is called or make an alert view that pops up when didRecieveMemoryWarning is called.

Also, run with Instruments app, its a great way to monitor your memory usage and identify memory leaks. Also try Product -> Analyze to find memory leaks from in-Xcode. Instruments is part of the SDK just search for it in spotlight.
