You can't compare NSStrings with the == operator. Basically what
you're doing there is comparing the addressed stored in the
pointers. You can use the isEqualTo: method to compare two
strings:
if ([rwdString isEqualTo:readString])
etc.
Also, it's probably a better idea to use indexOfSelectedItem
with constants for the item indices instead of
titleOfSelectedItem, in case you want to localize the program
late.

Hey all, I'm hoping someone can figure this one out.
I've set up an NSPopupButton in IB. It has three menu items -
Read, Write, and Delete.
In PB, I'm using if statements to try to get which item is
selected. I've set up one string to be [rwdMenu
titleOfSelectedItem] and three other strings that are just set
to Read, Write, and Delete. But the if statements won't work!
Using NSLog, I can see that the rwdString is either Read,
Write, or Delete, depending on which item is selected, but if I
do this:
if ( rwdString == readString )
NSLog (@"It's equal to Read");
else if ( rwdString == writeString )
NSLog (@"It's equal to Write");
else if ( rwdString == deleteString )
NSLog (@"It's equal to Delete");
else
NSLog (@"It's not equal to any of those, it's \"%@\"",
rwdString);
It ALWAYS tells me it's not equal to any of the strings, though
with the last NSLog entry, I see either Read, Write, or
Delete. What gives? Is the titleOfSelectedItem in some other
encoding than the other strings? Or will this just not work (I
hope that's not the answer, it would make things difficult!)?
Thanks for any help,
Mike (aka Darkshadow)
