Question

I am using Adobe Air3.4 to develop an app on iOS. However, I met a crash only on release version and this crash doesn’t happen on debug version. But I cannot get any crash info such as callstack from iOS. Do you have any method to deal with this kind of problem?

Answer 1

You can wrap the offending code in a try/catch statement. Inside the catch code block, you get an Error object that you can use to get the stack trace:

try
{
    // some code that throws an exception
}
catch (e:Error)
{
    trace(e.getStackTrace())
}

If you don’t know which code is causing the error, and thus where to add the try/catch statement, you might have some luck with the UncaughtErrorEvent — refer to the examples found at the bottom of the documentation for UncaughtErrorEvent that I linked to.

In fact, if you just want a stack trace in general, create a new Error object and use its getStackTrace() method anywhere in your code.

In addition to checking for errors as above, you should check the crash logs on your device to see if that provides any additional details.
