Is there a way to add a tag an IB object in such a way that it is
not visible to the user, but in such a way that I could reference
it from my app?
Maybe the -tag method: it returns a 32-bit integer.. It's settable
in IB as the control's tag value. I don't know if iPhone has it.
Since it's only 32-bits I don't know how useful it would be for
your intended purpose. But IB has no inherent use for it, and it
is readable from the app.
It *would* be useful, but IB doesn't let you set it to a string in
Cocoa. It's limited to numeric values, which makes it less useful
for humans.
For a bit of perspective, this is doable in *CARBON* apps, via the
'Command' attribute in Interface Builder. You can only use 4
characters, but it's damned useful. It's commonly used to create
interfaces that don't require hard linkage between the code and the
view. Somewhat ironically, despite that MVC is the law of the land
in Cocoa, this option is not available to Cocoa apps.
I was sure I was mistaken about this! Any other suggestions?
As was suggested, probably a utility app.
I know when I moved one of my apps from Carbon to Cocoa, I also
created IB palettes (later plugins) for all the UI. I put conversion
APIs around the 'tag' attributes. I could then enter/display four-
char codes.
