objective c - EXC_BAD_ACCESS in NSWindowController -

-

ok, situation bit complicated nature of issue should pretty simple more familiar me me cocoa memory management.

a few details : - main app, i'm loading "loadable" bundle (which consists of nswindowcontroller) - both projects (the main app , "plugin") arc-enabled

in plugin code, have custom initialization method :

- (id)initwithapi:(id)api {     pluginwindowcontroller* newpluginwindowcontroller = [super initwithwindownibname:@"pluginwindow"];      if (newpluginwindowcontroller)     {         [newpluginwindowcontroller setapi:api];     }      return newpluginwindowcontroller;  }

this how api declared :

@property (unsafe_unretained) id api;

now, here's catch :

  • i'm initializing using initwithapi: , api being set.
  • when i'm testing api's value in - (void)windowdidload: still shows fine.
  • however : when trying same thing within method (actually ibaction triggered button click in plugin's window)... trying [self api] triggers exc_bad_access error.

what doing wrong? ideas?

either declare property weak, if want automatically set nil when object dies, or strong, if want keep object alive (strong want).

unsafe_unretained result in dangling pointer if object deallocated (that's why called "unsafe"..)

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
