The value of the array is this

```
ListArray = [[NSMutableArray alloc] init];

ListArray = [NSMutableArray arrayWithObjects:@"Google", @"Samsung", @"Twitter", @"Facebook", @"Apple", @"NiKon", nil];

```

And when you click on the selectButton

```
NSString *select = [ListArray objectAtIndex:[_picker selectedRowInComponent:0]];

NSString *title = [[NSString alloc] initWithFormat:@"Select : %@", select];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:@"" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];

[alert show];

```

Receive a message box.
When you press OK, I want to go to select the value of the selected file.

But select value is 0.

I do not know how.
