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.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
