but my question is how i can give another array to my table view to retrieve information when i tap a button…i every where but i can’t find an answer…

Answer 1

The information displayed in your table view cells are determined in the cellForRowAtIndexPath method.

In your code, it looks like this method references your array named sortName.

If you are retrieving your new data set into some other array, then you have to replace the contents of sortName with the contents of the new array.
