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

- (void)endUpdates

Discussion of [UITableView endUpdates]
You call this method to bracket a series of method calls that began with beginUpdates and that consist of operations to insert, delete, select, and reload rows and sections of the table view. When you call endUpdates, UITableView animates the operations simultaneously. Invocations of beginUpdates and endUpdates can be nested. If you do not make the insertion, deletion, and selection calls inside this block, table attributes such as row count might become invalid.
