logging - My iOS app crashes on start up -
i have been developing ios app , of sudden when start debugger bunch of machine code , halts here:
0x2c70bb: popl %ebp 0x2c670bc: ret
i no output in log. when run zombies or leaks app runs fine, when use simulator nothing. put breakpointer in first line of code in app delegate , doesn't hit it.
any tips? went in code working code before happened , same thing. ive been developing ios 2 years , first.
i have searched solution have found nothing.
if app delegate not hitting crashing within autorelease pool statement in main.m.
without full stack trace it's difficult debug. i'd recommend following:
- make sure main window , root xibs ok
- stripping basics app delegate
also, inside main.m file, should see similar this:
uiapplicationmain(argc, argv, nil, nsstringfromclass([appdelegate class]));
the fourth argument delegateclassname, , apple docs says:
delegateclassname
name of class application delegate instantiated. if principalclassname designates subclass of uiapplication, may designate subclass delegate; subclass instance receives application-delegate messages. specify nil if load delegate object application’s main nib file.
so double check delegate class name being set either in applications main xib, or in delegate - i'd suggest being explicit , adding if isn't there.
