Question

I have a UITableView which I am creating by using custom UITableViewCell. The tableview shows some data populated from an array. Now I am using 2 image to highlight/unhighlight based on selection. [By default when application opens I am showing the first row with highlighted image without any selection].

The UITableView header contains one delete button now if I press delete button first time it happens succesfully.

-(IBAction)delete{
    [myArray removeObjectAtIndex:0];
    [tableview reloadData];
}

Now as tableview get refreshed, all row contains unhighlighted image. Now as I select 3rd row and press header delete button how should I get the index number to be deleted.

I know about didSelectRowAtIndexPath but is there any way which I put in IBAction method to get the selected cell index number?

Answer 1

Just create an ivar or property that holds the value of the latest selection. In the didSelectRowAtIndexPath method, have this line:

self.rowSelected = indexPath.row;

where rowSelected is a property. Then in your IBAction for the button, you can access that property:

-(IBAction)delete{
    if (self.rowSelected != -1){
        [myArray removeObjectAtIndex:self.rowSelected];
        [tableview reloadData];
        self.rowSelected = -1;
}

In the viewDidLoad method you should set the value of that property to 0 since you want the first row selected at start up.
