セルを指でスワイプしたときに行を削除したい。

私はこれを得た：

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"Delete");
}

実行後、削除ボタンが表示されますが、それを押しても何も起こりません。ブラケットに何を挿入する必要がありますか？

そして私の.m

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

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    NSString *str = cell.textLabel.text;

    NSLog(@"U selected %@", str);
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [self.dataSourceArray removeObjectAtIndex:indexPath.row];//or something similar to this based on your data source array structure
        //remove the corresponding object from your data source array before this or else you will get a crash
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.array = @[@"test",@"test"];

    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
    [refreshControl addTarget:nil action:@selector(updateArray) forControlEvents:UIControlEventValueChanged];
    self.refreshControl = refreshControl;
}

これを試して、

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

  if (editingStyle == UITableViewCellEditingStyleDelete) {
     [self.array removeObjectAtIndex:indexPath.row];//or something similar to this based on your data source array structure
//remove the corresponding object from your data source array before this or else you will get a crash
     [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 
  }
}
