PlCrashReporter Crash Report not showing backtrace for iOS

Question

I have integrated the PLCrashReporter Framework into my iOS app,

pls. ref : https://www.plcrashreporter.org/

http://rajatwork.com/?p=113

which works completely fine. It generates the crash log, convert it into protobuff format and sends an email in a text file format(with the protobuff data). The problem here is, the data which is decoded, does not match with the device crash log, i.e. it does not show the backtrace(present in the device log).

Below is the device crash log consisting of Last Exception Backtrace which is not present in the PLCrashReport.

Last Exception Backtrace:

20  UIKit                           0x3592b7fc -[UIApplication sendEvent:] + 376
21  UIKit                           0x3592b116 _UIApplicationHandleEvent + 6150
.

So is there a way to add "BackTrace" using PLCrashReport ?
