How use insertRowsAtIndexPaths IOS without reloadData

I don´t understand the insertRowsAtIndexPaths use. I need make a reloadData of my tableview for this work?

if don´t make a reloadData the application is crashing.


The app is crashing because the data source is not consistent before and after the insertRows call.

As an example if you are inserting one new row, you need to return 1 more row in tableView:numberOfRowsInSection: than before the insert call.

Here is an example to demonstrate

self.numberOfRows = self.numberOfRows + 1;
[self.tableView insertRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:0 inSection:0]] withRowAnimation:UITableViewRowAnimationAutomatic];
