Chapter 10 – Windows and Menus and Sheets
Page 206, “Loading a Nib With NSWindowController” paragraph
The code inside the loadEasyWindow: method and also the EasyWindow nib file must be modified as follows, in order to work with the recent (as of august 2013) version of Xcode and Objective-C:
EasyWindow nib file:
- add the easyController object to a mutable array (i called it controllers) in order to avoid its automatic release at the end of the method and so avoiding the premature deletion of the new window (Easy Window). Just place the array declaration** somewhere in the app delegate class, in the public or private interface (private would maybe make more sense) and then add the following line to the loadEasyWindow: method: [self.controllers addObject:easyController];
- set the File's Owner class to NSWindowController (using the identity inspector);
- set the window outlet of the File's Owner to the window in the EasyWindow nib file (ctrl-drag from the File's Owner icon to the window).
** Don't forget to actually instantiate the array! Do that in its getter or in the applicationDidFinishLaunching: method, for example.
