iOS学习笔记2—关于tableView的一些简单操作

1.删除：

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

{
     if (editingStyle == UITableViewCellEditingStyleDelete)
     {
         NSLog(@"....");
         NSUInteger row = indexPath.row;
         [self.editArray removeObjectAtIndex:row];
         [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:(UITableViewRowAnimationTop)];
    }
    
     //收藏数据更新
 //   [self replaceCurrentViewData:self.editArray];
    

}

  实现以上函数即可

2；移动：

 -(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath
{
    if (sourceIndexPath != destinationIndexPath)
    {
        id object = [self.editArray objectAtIndex:sourceIndexPath.row];
        [object retain];
        [self.editArray removeObjectAtIndex:sourceIndexPath.row];
        if (destinationIndexPath.row > [self.editArray count])
        {
            [self.editArray addObject:object];
        }
        else {
            [self.editArray insertObject:object atIndex:destinationIndexPath.row];
        }
        [object release];
    }
  //  [self replaceCurrentViewData:self.editArray];
}

3：插入

这个与删除行类似。实现下面，点击 +号即可。

3.1 首先将editingStyleForRowAtIndexPath方法中的UITableViewCellEditingStyleDelete修改成UITableViewCellEditingStyleInsert

  -(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
     if (editingStyle == UITableViewCellEditingStyleDelete)
     {
         NSLog(@"....");
         NSUInteger row = indexPath.row;
         [self.editArray removeObjectAtIndex:row];
         [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:(UITableViewRowAnimationTop)];
    }
    else

  {

      NSArray *insertIndexPaths = [NSArray arrayWithObjects:indexPath,nil];  

    //同样，将数据加到list中，用的row  

    [self.list insertObject:@"新添加的行" atIndex:row];  

    [tableView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationRight];

   } 

    //收藏数据更新
 //   [self replaceCurrentViewData:self.editArray];
    

}

4：标记：

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
 {
     UITableViewCell *oneCell = [tableView cellForRowAtIndexPath: indexPath];
     if (oneCell.accessoryType == UITableViewCellAccessoryNone) {
         oneCell.accessoryType = UITableViewCellAccessoryCheckmark;
     } else
         oneCell.accessoryType = UITableViewCellAccessoryNone;
     [tableView deselectRowAtIndexPath:indexPath animated:YES];
 }

 else {
     //我们实现的是在所选行的位置插入一行，因此直接使用了参数indexPath
     NSArray *insertIndexPaths = [NSArray arrayWithObjects:indexPath,nil];
     //同样，将数据加到list中，用的row
     [self.list insertObject:@"新添加的行" atIndex:row];
     [tableView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationRight];
 }
