Objective C Equivalent of PHP's "Variable Variables"

Question

In PHP and in JavaScript you can dynamically use a variable by using another variable as part of its name. I do not want to use an array as part of the solution. Can this be achieved in Objective C? I'd like to do something like this:

for (int i=1; i<6; i++) {
        if([appRecord.answer(i) length] != 0){
            self.textView.answer(i)ViewSingle.text = appRecord.answer(i);
        }
}

Answer 1

No. But you can give a tag to the view and use -viewWithTag:.

Answer 2

Short answer: No.

Long answer: Kind of.

1. You can use an array, store your variables in there, and index into it.
2. You can use a dictionary, store your variables as values, and look them up by key.
3. You can declare all your variables as @property, and then use [self valueForKey:] to look them up by name.
4. You can build the name of the ivar as a string, and then use something like object_getInstanceVariable() to retrieve it's value directly (this is similar to #3, except you don't have to declare it as an @property).
5. If you're dealing with views, you can assign each view a unique tag and then retrieve it via [superview viewWithTag:aTag].

EDIT: Note that this only works with instance variables. This does not work with global/static variables.
