Answer 1

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath : indexPath];
if (!(cell == nil)) {
name = (UILabel *)[cell viewWithTag:10]; name.text = [result objectAtIndex : indexPath.row];
}
name.tag=indexPath.row;
return cell;
}
In this datasource method, you have used a "if" condition, and due to your cell is reusable cell, so you have to use the else part too in this data source method.
Like
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath : indexPath];
if (!(cell == nil)) {
name = (UILabel *)[cell viewWithTag:10]; name.text = [result objectAtIndex : indexPath.row];
}
else{
name.tag=indexPath.row;
}
return cell;
}
Thanks

Answer 2

Try this way
[result removeObjectAtIndex:indexPath.row];
[tableView reloadData];// comment this line above code
[spinner stopAnimating];
//After that you can add
[tableView reloadData]; // above stopanimating line.
Add this cellForRowAtIndexPath method
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath : indexPath];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:#"cell"];
}
name = (UILabel *)[cell viewWithTag:10];
name.text = [result objectAtIndex : indexPath.row];
name.tag=indexPath.row;
return cell;
}
