View Full Version : Is there any easy way to reference sequential variables in a for loop?

Hey guys...

If I have a bunch of objects named "sq1", "sq2", "sq3", etc. Is there an easy way to reference each from within a for loop?

For instance, in ActionScript I could do...


...or something like that. Is there an Objective-C equivalent?

Instead of creating hard-coded variables with names which you wish to access sequentially, create an array. Then you just access them with an index.

Alternative two, you could create a dictionary of the variables and reference them by string, but that doesn't seem like the best option.

create an array

I second that!
An array is a data structure consisting of a group of elements that are accessed by indexing and that is what you need to use in this situation.
