Help with some bug fixes?


#1

Hello -
I am a former iOS BNR student, finished this past July ('12) and I am now attempting to create my first Mac OSX App. I am doing pretty well, its my first app. I am running into a few issues with my app and was wondering if someone could help me identify why I am getting random crashes after certain tasks and advice on how to fix them.

Preference Window Bug
I have a preference window and I can launch it, once I close it I can not launch it again. The “Preferences” option is greyed out in the app menu and all functionality of my app stops working (NSSearchbar, buttons, etc…) If you wait long enough the app will just crash entirely. I think its something to do with how the preferences are saved but I am not sure. Here is my code for the preference controller. Some of the preferences get saved when the preference window is closed but some do not. (Checkbox and Popup Button do, NSTextField does not).

I do not know if I am looking in the right place or not and if there is a better way to share my entire project please let me know.

Thanks!!
