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];
}
