I put my question from the comment section here:


so I tried the following to get the thing to move on to different Views.

I created View1.xib, View2.xib and View3.xib

In Method UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];

I iterate the int variable i, which is declared in RootViewController.h to give me the table cell output like:
Cell 1
Cell 2
Cell 3

This works fine.

I rewrote the didSelectRowAtIndexPath method to the following, to get to different views on the individual cells, but it will always go to View3. Why? can anyone help me with that?

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic

if (self.view2ViewController == nil) {
    if (i == 1) {
        View2ViewController *view2 = [[View2ViewController alloc] initWithNibName:@”View1″ bundle:[NSBundle mainBundle]];
        self.view2ViewController = view2;
        [view2 release];
    }
if (i == 2) {
    View2ViewController *view2 = [[View2ViewController alloc] initWithNibName:@”View2″ bundle:[NSBundle mainBundle]];
    self.view2ViewController = view2;
    [view2 release];
    }
if (i == 3) {
    View2ViewController *view2 = [[View2ViewController alloc] initWithNibName:@”View3″ bundle:[NSBundle mainBundle]];
    self.view2ViewController = view2;
    [view2 release];
    }

}
[self.navigationController pushViewController:self.view2ViewController animated: YES];
}

Kind regards. Nico

Uhu,

Where is the “i” variable comming from and where is it being changed?  To get access to the indexPath variable as an integer, you need to call:

indexPath.row

This will give you the integer value of the cell that the user clicked on.

But the indexPath.row hint is worth a million to me :)

Kind regards. Nico

Set an integer to indexPath.Row and got an error.


NSInteger *my_index;

my_index = indexPath.Row;

Warning: assignment makes pointer from integer without a cast

When declaring an NSInteger, you don't need the “*”. This is most likely the problem.
