Load the table view again after returning form another view

Question

hey, when my application loads i have a table view which shows data present in my database. On clicking the add button it goes to another view and the data inserted is updated in the database. Now how do i load this updated data when i return from this view to the first view.

Which method do i need to call? ViewDidAppear? or ViewWillAppear? and how do i reset the entire table view n reload the data?

Answer 1

In viewWillAppear: call [self.tableView reloadData].

Answer 2

You can update the rows yourself by calling

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

This will give you the option to have the new row(s) appear in the tableview animated
