Question

Is there anyway to make a UITableViewRowAnimation animate at the same time?

Such as, If I’m adding 4 rows to a TableView, animate the block of 4 rows rather than animating both row individually?

Snippet, tutorial for custom animation etc are welcome !

There are several ways as described in the docs:

Batch Insertion, Deletion, and Reloading of Rows and Sections

The UITableView class allows you to insert, delete, and reload a group
of rows or sections at one time, animating the operations
simultaneously in specified ways. The eight methods shown in Listing
7-7 pertain to batch insertion and deletion. Note that you can call
these insertion and deletion methods outside of an animation block (as
you do in the data source method
tableView:commitEditingStyle:forRowAtIndexPath: as discussed in
“Inserting and Deleting Rows in Editing Mode”).

Listing 7-7 Batch insertion and deletion methods

- (void)beginUpdates;
- (void)endUpdates;

- (void)insertSections:(NSIndexSet *)sections withRowAnimation:(UITableViewRowAnimation)animation;
- (void)deleteSections:(NSIndexSet *)sections withRowAnimation:(UITableViewRowAnimation)animation;
- (void)reloadSections:(NSIndexSet *)sections withRowAnimation:(UITableViewRowAnimation)animation;

- (void)insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation: (UITableViewRowAnimation)animation;
- (void)deleteRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation: (UITableViewRowAnimation)animation;
- (void)reloadRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation;
