UITableView不会从NSUserDefaults中删除记录

Question

这是我删除值的代码。当我重新启动应用程序时，表视图正在删除临时记录，它也会显示已删除的记录...

-(void)tableView:(UITableView *)atableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [bookmarks removeObjectAtIndex:indexPath.row];
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationFade];
       [[NSUserDefaults standardUserDefaults] setObject:bookmarks forKey:@"Bookmarks"];  [self.tableView reloadData];
    }
}

请帮助。

试试这个：

// Your code    
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];  
[prefs setObject:bookmarks forKey:@"Bookmarks"];    
// saving it all  
[prefs synchronize];
