Lets say I have some custom code that does the same thing, with the
exception that a few IBOutlets are different for each type. Instead
of having multiple methods, is there a way to use 1 IBAction, and take
necessary action depending on where it was sent?
I originally used code like this:
- (IBAction)barDoSomething:(id)sender
{...}
- (IBAction)fooDoSomething:(id)sender
{...}
I didn't want a plethora of functions though, so I used code like
this, with the object id's coming from IB:
- (IBAction)doSomething:(id)sender
{
if ([sender objectID] == 192])
[foo doSomething];
else if ([sender objectID == 236])
[bar doSomething];
}
There were two problems with this, though. One, there was a lot of
repeated code, even without the repeated methods, and 2, it didn't
work. (anybody know why? I NSLogged the objectID's and they loged
objectID to the console- no number)
What I'd really like is one method that uses the appropriate bar or
foo (NSTableViews), and sends to the appropriate array controller, all
depending on which button sent the message. I'd have one piece of
code, like this:
- (IBAction)doSomething
{
[correctClass doSomething];
}
And appropriate methods/controllers/tableviews/etc. would be used.
Any techniques that could be used for this? Maybe using sender? I'm
open to Obj-C++ if that's needed, just trying to find a working
solution. Also, what would be Obj-C convention for situations like
this, if there is no solution, or if I was doing it the traditional
way (code snippet 1?)
To summarize:
- What's the traditional way of handling a situation like this?
- Why aren't the objectID's working?
- What solutions are there?
Thanks,
