tableView didSelectAtRowIndex:?

[Dan the Man]

hello I'm am trying to do 2 things.
I have a Table View and when i click on a cell how can I:
1. get the cell number and alert it in a UIAlertView
2. push the view to the left, to go to a detail View?

didSelectRowAtIndex passes in an IndexPath. it has two properties row and section. If you only have one section then the row is the row.

TableViews work with NavigationControllers, when someone selects the row, you create a new viewController and push it onto the nav controller's viewController's stack.

Hope that helps explain it.

-(void)didSelectRowAtIndexPath:(IndexPath *)indexPath {
    int row = [indexPath row];
    [someMethodToShowAlert:row];
    MyViewController *detailView =[[MyViewController alloc] init…..]
    [detailView setDataToPass:dataToPass];
    [navController pushViewController:detailView];
    [detailView release];
}

Um... I tried that but, it doesn't want to write the...

[indexPath row]

...into the alert view. How do I do that?

Put this in the alertview code

[NSString stringWithFormat:@"Selected Row is %d",indexPath.row];

All right cool , it works. But how do I make it work between multiple sections?

Usually with multiple section you have an NSDictionary to hold the data. Each key is a section. You can get an array of keys from the NSDictionary. The get the key at index from the NSArray objectAtIndex method, passing in the [indexPath section] value. Then you get the values out of the Dictionary under that key. That is usually an NSArray. So in that last NSArray get objectAtIndex [indexPath row]

Now you have the data for that particular row.
