Hello,
I'm trying to create a simple calculator as an exercise and I have
attached all the numeric buttons to one action in my controller class.
I was planning on figuring out which button has been pushed via the
[sender tag] method. I've set all the tags to match the numeric values
(i.e. the button I want to represent 7 has a tag of 7).
When the button is pushed I can't seem to get a valid tag value
however. Invoking [sender tag] within the action simply gives me 0 no
matter what button has been pushed.
Any clues?
Are your buttons in an NSMatrix? If so, [sender tag] is probably
giving you the tag for the matrix, not for the selected button cell.
To get that tag, you could do something like [[sender selectedCell]
tag].
