I tried foolishly to create a document based application. 2 things
happen
When I save the document, close the application and then double click
the document certain things become inaccessable. The Document is
based on 1 dictionary and one array. It's the dictionary that I
cannot access at all. If I log the dictionary, it is all there.
However, I cannot access ANYTHING FROM ANYWHERE including from within
the document class. I have tried making accessors but no matter what
they return nil. I can access the dictionary outside the document
class but I cannot extract anything from it.
second Absolutely nothing I do allows me to access ANY NSTextfield. I
cannot retrieve data from them or set their values
finally, if I doulbe click a document the app opens or it opens the
doc, if I close the document and double click the icon, of if I
double click the icon with no other windows open in the app, it
crashes, sigbus 10
Very hard for us to help without a better description of what you are
doing in your code, showing code is the best way.
Basically how are you saving the data into your document and how are
you getting it back out of your document.
I was using the built in stubs when you start a doc based app in xcode.
Basically I just turned the entire thing into a dictionary. Not to
hard. two objects to add too it is all. And saved it to disk
then simply restore the dictionary.
resotredDictionary = [someString propertyList]
someDict setDictionary:retoredDictionary
How is the NSTextField issue related to your document or is it?
Because among other things I cannot seem to retrieve ANY information
from documents after they are saved I can nslog the variables they get
put into and the info is there it's just inaccessable.
Part of the textfield problem it would seem however was that I had
named the two textfields i needed to set something that xcode or IB or
something did not like. I changed the names and they started to be
settable from other sources. I still cannot get the save and restore to
work though.
