(If you have a table view that uses multiple styles of the same type of cell, you can suffix
the reuse identifier with the name of that style, e.g.
UITableViewCell-Default
.)
Reusing cells means that you only have to create a handful of cells, which puts fewer de-
mands on memory. Your application's users (and their devices) will thank you. Build and
run the application. The behavior of the application should remain the same.
