macOS [SDK] NSDictionary problems

[Duke Leto]

I have been having problems accessing an object in an NSDictionary I defined.

Is there a way to show what is in an array or dictionary on some kind of debugging console? Or can I see the contents of an IndexPath on a console?

Will

– allKeys

then using fast enumeration over the resulting array and calling:

– objectForKey:

on each then printing the key/values not do?

How do you print them is what I'm asking. I sorta jumped into Obj-C, XCode, and the SDK all at once so I left some knowledge behind.

Oh... the traditional means are:
NSLog(NSString *format, ...);
http://www.cocoadev.com/index.pl?NSLog
This will go to the XCode console

or

fprintf(stderr,format,...);
This will go to stderr (I think that ends up at the console in XCode as well).

Well I got i think I found the problem, but I have no idea why it is there.

The array in question is in the AppDelegate. My class uses the AppDelegate to read and write from that array. This is very similar to the SimpleDrillDownApp.. However, this array does not like being in the viewWillAppear method. In any case, I may ditch the entire array idea and try to learn SQLite.

Hopefully I will be done by June...
