ios - 为什么我的搜索结果不会链接到我的详细视图？

Question

我有一个带有搜索栏的 UITableView，搜索栏可以工作，但结果不会链接到我的详细视图。下面的代码：

#import "firstTableViewController.h"
#import "detailViewCell.h"
#import "DetailViewController.h"

@interface firstTableViewController ()

@end

@implementation firstTableViewController
@synthesize craftingItems1;
@synthesize bigImages;
@synthesize theText;

@synthesize searchDisplayController;
@synthesize searchResults;

- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
    // Custom initialization
}
return self;
}

- (void)viewDidLoad
{
[super viewDidLoad];
self.craftingItems1 = [[NSArray alloc] initWithObjects:
                       @"Item 1",
                       @"Item 2",
                       @"Item 3",
                       @"Item 4",
                       @"Item 5", nil];


self.theText = [[NSArray alloc] initWithObjects:
                @"Description 1", 
                @"Description 2", 
                @"Description 3", 
                @"Description 4", 
                @"Description 4", nil];


self.bigImages = [[NSArray alloc] initWithObjects:
                  @"Image 1.png", 
                  @"Image 2.png", 
                  @"Image 3.png", 
                  @"Image 4.png", 
                  @"Image 5.png", nil];


}

- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}

详细视图通常与表格一起使用，但是当使用搜索时，项目列表不会链接到详细视图。
