In a nutshell,

YourViewControllerClass * vc = [[YourViewControllerClass alloc]init];
[self presentViewController:vc animated:NO completion:nil];

Hope this helps :)

First add the item to the array, then reload your table view.

Assuming you declared all properties needed including the array used by the data source.

@property(nonatomic, retain)NSMutableArray *modalArray;

The IBAction on Save button should include the following code:

//Add the item to the array
[self.modalArray addObject:[NSString stringWithFormat:@"%@",txtField.text]];

//Rest of your code, dismiss the modal view

Once dismissed, you need to reload the table view to show up the recent value saved on the modal view.

[self.yourTableView reloadData];

reloadData will call implicitly the data source method tableView:cellForRowAtIndexPath: which will loop the array again and so show you the new value.

If you need the presentModalViewController to be removed and then the tableView to be reloaded then use this

[yourTableView reloadData];

on the viewWillAppear of the initial view.
