【问题描述】：

我有一个 UISearchBar 和 tableview 显示数据。当我搜索时，结果正在获取并且能够传递搜索到的电影名称，但无法传递特定搜索结果的电影 ID，我尝试过但无法找到解决方案。以下是我尝试过的，请帮助，TIA。

// output of url

DataTable: 
searchByCategory: [

movie_id: "56",
movie_name: "Avengers"
,

movie_id: "20",
movie_name: "Kong Skull Island"
,
.
.
.
]



// Swift file
var moviesArray = [[String:AnyObject]]()
var searchArr = [""]
var searching: Bool = false
var filtered:[String] = []

// Response

func getSearchResults(url: String, parameters: [String : String])

        Alamofire.request(url, method: .post, parameters: parameters).responseJSON
            response in
            if response.result.isSuccess

                print("Success! Got the response")

                let responseData = JSON(response.result.value!)

                if let resData = responseData["DataTable"]["searchByCategory"].arrayObject

                    self.moviesArray = resData as! [[String:AnyObject]]

                

                for i in 0..<self.moviesArray.count 

                    let dict = self.moviesArray[i]

                    let movieName = dict["movie_name"] as? String
                    self.searchArr.append(movieName!)

                    




// numberOfRowsInSection 

        if searching

           return  filtered.count
        
        else
            return moviesArray.count
        

    

// cellForRowAt indexPath: 

 if searching 
         cell?.textLabel?.text = filtered[indexPath.row]
        else
        
         let dict = moviesArray[indexPath.row]
         cell?.textLabel?.text = dict["movie_name"] as? String
        





// didSelectRowAt indexPath:

if(searching)
  let movieDetails = MoviesViewController(nibName: "MoviesViewController", bundle: nil)
movieDetails.resDetails = self.filteredId[indexPath.row]
// Here am not able to pass the movie_id of the search results, i can only pass the movie name
navigationController?.pushViewController(movieDetails, animated: true)

else




// Search Method

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String)
    
        filtered = searchArr.filter( (text) -> Bool in
            let tmp: NSString = text as NSString
            let range = tmp.range(of: searchText, options: .caseInsensitive)
            return range.location != NSNotFound
        )

        if(filtered.count == 0)
        
            searching = false;
        
        else
        
            searching = true;
        

        self.searchList.reloadData()
    

【问题讨论】：

您想从结果中获取电影 ID 并附加到 searchArray 或其他内容吗？不清楚

我想将特定搜索的电影 id 传递给 didSelectRowAt indexPath

【参考方案1】：

 var isSearchNull: Bool = true 
        didSet 
               tableView.reloadData()
            
        
    


func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int 
        var numberOfRows = 0
        if isSearchNull 
            numberOfRows = moviesArray.count
         else
            numberOfRows = filtered.count
        
        return numberOfRows
    

搜索委托

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
    filtered.removeAll() // the array of search i guess its filtered 
    guard let textToSearch = searchBar.text, !textToSearch.isEmpty else 
        return
    

    isSearchNull =  textToSearch != "" ? false : true

    if !isSearchNull  
        if Date().timeIntervalSince(previousRun) > minInterval 
            previousRun = Date()
            fetchResults(getSearchResults(url : url ) // your networking process
        
    

和

func getSearchResults(url: String, parameters: [String : String])
    //// network
     fetchData() [weak self ] 
         guard let self = self else  return 
            if let error = error 
                print(error)
            

            guard let result = result, !result.isEmpty else  return 
            self.filtered = result
    

最后

 private var filtered:[String] = []
  
        didSet 
            DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) 
                self.tableView.reloadData()
