I'm new to Cocoa and Objective-C, so I'm following the Lynda courses and learning a lot. Thing is, I've encountered a problem that I cannot figure out, even though I seem to be doing it exactly the same way...
Basically, I'm trying to get a Table View hooked up through bindings to an Array Controller, just to list out the contents of a simple NSMutableArray in my code. I'd gotten it all hooked up properly, but no matter what I did it wasn't displaying anything when I ran the program.
Here's where it gets weird: on a lark, I added a "+" button and hooked it into the "add" function of the Array Controller, and when I ran the app and clicked that button, it not only added a new line, but it displayed the whole array as well! Apparently everything had been hooked up properly the whole time, it just wasn't displaying the information. Further experimentation revealed that I could make any changes I wanted to the array, whether in the original code or during the runtime of the app, but they would only be updated in the Table View when I clicked that "+" button.
I feel like this is probably a simple solution, just some "Continuous" box that needs to be checked or something, but I cannot for the life of me find it... Can anyone point out what I need to do to get my TableView to show its contents automatically?
(Also, I don't know if this is related or not, but none of the "Model Key Path" fields in the inspector are offering suggestions as I type, which they do in the Lynda course. The app works fine if I manually type everything in, but it says "no completions found" the whole time.)
Thank you in advance for helping out a n00b!

As I understand it this is probably because the NSMutableArray
that holds your data array i.e. dogPound
or similar, isn't also declared as a property, only an instance variable.
Declare the property @property NSMutableArray * dogPound;
and change the instance variable declaration to _dogPound
and I think interface builder should offer you the auto-completes.
