Logs from App crashing

[shaun-h]

I have been playing around with the objc_utils module and it is really a great module. Although I have been having a few crashes when trying out some specific code now that I'm not asking for help with the code, but does pythonista generate logs when it crashes if so is there something that I could use to read those logs to help with debugging my code, if not it might be a suggestion for a future release that if pythonista crashes it shows on the next start why it happened if that is possible.

Any suggestions would be great thanks.

Just seeing if anyone has any suggestions for this, I have been trying to play with NSUncaughtExceptionHandler but I am having no luck with even accessing it, it appears to be a data type in Foundation framework so if anyone had pointers on how to access that would be awesome.

this was my attempt... the problem i think is that the main runloop does catch exceptions, so there won't be any unhandled exceptions.

# coding: utf-8
from objc_util import *

NSException=ObjCClass('NSException')
def handleException_(exception):
	with open('exception.txt','w') as f:
		f.write('exception'+ObjCInstance(exception).__repr__())
		f.write(dir(exception))
		f.write(vars(exception))

ETYPE = ctypes.CFUNCTYPE(None, c_void_p)
fp = ETYPE(handleException_)
retain_global(fp)

c.NSSetUncaughtExceptionHandler.argtypes=[c_void_p]
c.NSSetUncaughtExceptionHandler(fp)

possibly ther may be a way with applicationWillTerminate_, or c.sighandler.

It is usually easier just to put logging statements in your python to figure out which obj call is crashing.

Thanks for trying, I will go with trying to put log statements in, just thought it might be easier to catch if I missed something though.
