（1）第一步设置一下button

    IBOutlet NSButton * nameOrderBT;
    IBOutlet NSButton * sizeOrderBT;

（2）切换设置切换相遇函数

-(IBAction) nameOrderAction:(id)sender
{
    
    [sizeOrderBT setTitle:@"Width"];
    if ([nameOrderBT.title isEqualToString:@"Name??"]) 
    {
        [nameOrderBT setTitle:@"Name??"];
        
        _itemOrder=RFICONMODEL_ORDER_FILENAME_DESC;
        
    }
    else{
        [nameOrderBT setTitle:@"Name??"];
        _itemOrder=RFICONMODEL_ORDER_FILENAME_ASC;
    }
    [self updateTable];
    return;
    
}
-(IBAction) sizeOrderAction:(id)sender
{
    [nameOrderBT setTitle:@"Name"];
    if ([sizeOrderBT.title isEqualToString:@"Width??"]) 
    {
        [sizeOrderBT setTitle:@"Width??"];
        _itemOrder=RFICONMODEL_ORDER_IMAGEWIDTH_DESC;
    }
    else{
        [sizeOrderBT setTitle:@"Width??"];
        _itemOrder=RFICONMODEL_ORDER_IMAGEWIDTH_ASC;
    }
    [self updateTable];
    return;

}

（3）设置item获取顺序

{
    if (_itemOrder==nil) {
        _itemOrder=@"";
        
    }
    return _itemOrder;
}


-(NSMutableArray*) getItemsArray
{
    if (itemsArray==nil) {
        itemsArray=[NSMutableArray array];
        //NSArray * modelArray=[RFIConModel getItemByGroupName:[self getGroupNameBySafe]];
        NSArray * modelArray=[RFIConModel getItemByGroupName:[self getGroupNameBySafe] order:[self getItemOrderBySafe]];
        for (RFIConModel * model in modelArray) {
            ItemPreCellVC * oneVC=[[ItemPreCellVC alloc] init];
            oneVC.itemModel=model;
            [itemsArray addObject:oneVC];
        }
    }
    return itemsArray;
}

其中[RFIConModel getItemByGroupName:[self getGroupNameBySafe] order:[self getItemOrderBySafe]]是order关键，这样只需设施一下itemOrder，就可自动更新内容了。
