Lets say I have some custom code that does the same thing, with the

of having multiple methods, is there a way to use 1 IBAction, and
take necessary action depending on where it was sent?
If I read your post correctly, you want one action, called by
various controls, and you want to do different thing depending on the
sender, right?
For this, we use tags (on the controls). Let's use a concrete
example: a media player. You might have a "-seek:" action method. You
might have four buttons (seek back, seek back FAST, seek forward, seek
forward FAST). Depending on the sending button, you need your media
controller to do the right thing.
- (IBAction)seek:(id)sender
{
int tag = [sender tag]; // or NSInteger tag = [sender tag];
switch (case)
{
case 1001: // seek back
[self seekBack];
break;
case 1002: // seek back FAST
[self seekBackFast];
break;
case 1003: // seek forward
[self seekForward];
break;
case 1004: // seek forward FAST
[self seekForwardFast];
break;
default:
NSBeep(); // don't know what to do here ...
break;
}
}
Don't forget to set the tags in IB for your controls.
