Question

My program has a tableview, I want to show selected items from the tableview in a textview

I have following code which shows only the last item of the NSMutablearray in textview:

I guess problem is the for loop but couldnt figure it out.

stands is NSMutablearray, selectItems is NSMutablearray, selected items is UItexview.

- (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {
    [selectItems addObject:[stands objectAtIndex:indexPath.row]];    
    for (NSString *yourVar in selectItems) {

        selectedItems.text=yourVar;
        NSLog (@"Your Array elements are = %@", yourVar);

    }

    [self.mytableView reloadData];
}

I try the following but it crashes:

[selectItems addObject:[stands objectAtIndex:indexPath.row]];  
int length = [selectItems count];

    for(int i=0;i<=length;i++){
        selectedItems.text= [selectItems objectAtIndex:i];
    }

how can I show all the items of NSmutablearray in a texview ?

Answer 1

- (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {
    [selectItems addObject:[stands objectAtIndex:indexPath.row]];    
    NSMutableString *exString = [[NSMutableString alloc]init];
    for (NSString *yourVar in selectItems) {

        NSLog (@"Your Array elements are = %@", yourVar);
        [exString appendFormat:@"\n%@",yourVar];

    }
    selectedItems.text=exString;

    [self.mytableView reloadData];
}

What about something like this? It takes each object, puts a newline in it, then adds it to exString to form one long chain of the objects in your array.
