TableView reloadData vs. beginUpdates & endUpdates

Question

I got a tricky problem regarding updating my TableView, i get different results using different methods of updating it, let me explain:

Situation 1:

Answer 1

From the UITableView documentation

beginUpdates
Begin a series of method calls that insert, delete, or select rows and sections of the receiver.

That means, you should not use this unless you are inserting, deleting or selecting. You are doing neither of these.

Also, you should end beginUpdates with endUpdates, not reloadData. Documentation:

This group of methods must conclude with an invocation of endUpdates.
