[baseten-users] BXDatabaseContext usage

[Réjean Lamy]

Correct me if I'am wrong,  my understanding of KVC is:

- We can access object instance variables directly with key-value,  
there is no need to have getter/setter for the variable. The variable  
must be an Object.
- If we provides getter/setter for the variable, key-value will use it.

About IBOutlet, to me, its simply a keyword that provides the variable  
visibility to IB. Actually I don't connect this Outlet in IB to  
anything, but simply bind the variable.
We can remove the IBOutlet keyword from the declaration, the result  
will be the same.
