Is there a way to enumerate the outlets of an object automatically?
In a certain type of controller object I'm finding I'm writing a
lot of code
like this:
[myOutlet1 setEnabled:NO];
[myOutlet2 setEnabled:NO];
... etc for another several dozen outlets ...
[...]
Lastly, you could write a proxy object, put it in your nib, and hook
up all of the outlets to it instead. The proxy would intercept all
setFoo: messages by forwarding them to your real object and
simultaneously building a dictionary. This will be sure to only get
real outlets.
I'm not sure I understand -- would the proxy object have outlets to
myOutlet1, myOutlet2, etc.?
In any case this reminds me of a silly hack I used in the NeXTstep
days, which was to use an NSMatrix to hold an array of things. In
this case, the hack would be to create a matrix with one cell for each
of the outlets you want to treat as a group, and point to the cell's
target to the outlet object. Then, instead of your dozens of
setEnabled: calls, you can simply iterate through the matrix. But
really this is just a variation on manually setting up the dictionary.
