将附加视图添加到 TableViews 层次结构的前面

问题描述

我有一个表格视图，它是城市 => 建筑类型 => 计算。以下代码摘录。

我想在前面添加额外的视图，所以它是区域 => 城市 => 建筑类型 => 计算

每个地区都有相似的数据。

我是否需要为区域设置另一个 NSArray 并将位置嵌套在其中。有什么地方可以指点我吗？

#import "LocationViewController.h"
#import "Location.h"
#import "LocationCell.h"
#import "LocationDetailViewController.h"

@interface LocationViewController ()

@end

@implementation LocationViewController

{NSArray *exitlocations;
}

- (void)viewDidLoad {
[super viewDidLoad];
//Initialise table data

//1st Location
Location *location1 = [Location new];
location1.locationtitle = @"dublin";

location1.buildingtype = [NSArray arrayWithObjects:@"Office Prime",@"Office     Secondary",@"Industrial < 500 sq m",@"Industrial > 500 sq m",@"Logistics Facility",@"Hotel 5 Star",@"Hotel 3/4 Star",@"Student Residences (PBSA)",@"Residential (PRS)",nil];
