Hello,
I just completed the tutorial
(
http://developer.apple.com/documentation/Cocoa/Conceptual/
CurrencyConverterBindings/index.html#//apple_ref/doc/uid/TP40001095) on
Cocoa bindings and am trying to convert the text field for the
"Exchange Rate" such that it:
1. Displays the number as a percentage (done)
2. Uses the actual decimal value in the bindings (i.e., divide the
number in the box by 100)
So I created a "Value Transformer" class, but since this is a "Document
Based Cocoa App", I have no idea how/where I should
register the transformation at. The docs say to use..
[NSValueTransformer setValueTransformer:etcetcetc]
In the "initialize:" class message (or in
applicationDidFinishLoading:), but I don't know how or where to set my
controller as a delegate to receive these messages (This is a Document
based application and IB does not show me a "delegate" outlet when I do
the usual control-drag from File's Owner to the controller)
Any help would be much appreciated.
Thanks,
Rick Bischoff
