表搜索segue不匹配表segue

Question

我已经在tableview上实现了“搜索栏和搜索显示控制器”，并且可以在我输入时在新表中查看我的结果。我的问题是我在搜索列表中点击的单元格不会导致与表格中的单元格相同的详细信息页面。我知道问题在于我的segue中的indexPath.row，但我不知道如何解决这个问题。

我想我的问题归结为，我如何让两张桌子都指向相同的详细信息页面？

以下是我的代码：

#import "BuildingsViewController.h"
#import "BuildingsMapViewController.h"

static NSString *CellIdentifier = @"buildingsCell";

@interface BuildingsViewController ()

@property (nonatomic) NSArray *keys;
@property (nonatomic, strong) NSMutableArray *tempMutableArray;

@end

@implementation BuildingsViewController


- (void)viewDidLoad
{
    [super viewDidLoad];

    [self performSelector:@selector(retrieveBuildings)];

    [self setTempMutableArray:[[NSMutableArray alloc] init]];
    [self.searchDisplayController.searchResultsTableView registerClass:[UITableViewCell class]
                                                forCellReuseIdentifier:CellIdentifier];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.

更新的代码（在segue上崩溃）：

#import "BuildingsViewController.h"
#import "BuildingsMapViewController.h"

static NSString *CellIdentifier = @"buildingsCell";

@interface BuildingsViewController ()

@property (nonatomic) NSArray *keys;

@property (nonatomic, strong) NSMutableArray *tempMutableArray;

                                                forCellReuseIdentifier:CellIdentifier];
