如何在swift 3.1.1中使用getter setter方法搜索栏？

Question

我在我的应用程序中实现了搜索栏。我有一些酒店的JSON数据。 （姓名，图片，地址，手机号码，电子邮件）。我在搜索结果中获得了该名称，但我想要获取特定酒店的全部数据。所以，请帮助我实现搜索功能。我想使用getter setter方法。请帮忙。提前致谢！！

let str = self.catArr [indexPath.row] 
    let url1 = "myapi" 
    let url2 = url1+str 

    let allowedCharacterSet = (CharacterSet(charactersIn: " ").inverted) 
    if let url = url2.addingPercentEncoding(withAllowedCharacters: allowedCharacterSet) 
    { 
     Alamofire.request(url).responseJSON { (responseData) -> Void in 

      if (responseData.result.value) == nil 
      { 
       print("Error!!") 
      } 

      //if (responseData.result.value) != nil 
      else 
      { 
       let response = JSON(responseData.result.value!) 

       if let resData = response["data"].arrayObject 
       { 
        self.arrResponse1 = resData as! [[String: AnyObject]] 

        for item in self.arrResponse1 
        { 
         let name = item["name"] as! String 
         self.arrName.append(name) 

         let add = item["address"] as! String 
         self.arrAddress.append(add) 

         let web = item["website"] as! String 
         self.arrWebsite.append(web) 

         let email = item["email"] as! String 
         self.arrEmail.append(email) 

         let mob = item["mobile"] as! String 
         self.arrMobile.append(mob) 

         let city = item["city"] as! String 
         self.arrCity.append(city) 

         let state = item["state"] as! String 
         self.arrState.append(state) 

         let dist = item["district"] as! String 
         self.arrDistrict.append(dist) 

         let area = item["area"] as! String 
         self.arrArea.append(area) 

         let img = item["image"] as! String 
         self.arrImage.append(img) 

         let rating = item["rating"] as! String 
         self.arrRating.append(rating) 

         let id = item["id"] as! String 
         self.arrId.append(id) 
        } 
       } 
      } 
     } 
    } 

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
{ 
    filteredName = self.nameArr.filter({ (String) -> Bool in 
     let tmp: NSString = String as NSString 
     let range = tmp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive) 
     return range.location != NSNotFound 
    }) 

    if(filteredName.count == 0) 
    { 
     searchActive = false; 
    } 

    else 
    { 
     searchActive = true; 
     print("Search Array = \(filteredName)") 
    } 

    self.infoTableView.reloadData() 
} 

//在tableview中 表示如果（searchActive） { cell.lblName.text = self.filteredName [indexPath.row] }

else 
    { 
     let urlImage = str1+self.imageArr [indexPath.row]+".jpg" 

     cell.imgView.sd_setImage(with: URL(string: urlImage), placeholderImage: UIImage(named: "")) 
     cell.lblName.text = self.nameArr [indexPath.row] 
     cell.lblAddress.text = self.addressArr [indexPath.row] 
     cell.lblCity.text = self.cityArr [indexPath.row] 
     cell.lblPhone.text = self.mobileArr [indexPath.row] 
     cell.lblEmail.text = self.emailArr [indexPath.row] 
     cell.lblStar.text = self.ratingArr [indexPath.row] 

     cell.phoneString = self.mobileArr [indexPath.row] 
     cell.emailString = self.emailArr [indexPath.row] 
    }

具有多个数组来存储代替每个值你需要的是自定义class/struct对象的数组，然后使用它便于使用filter。

struct Item { //Make some suitable name 
    let id: String 
    let name: String 
    let address: String 
    let website: String 
    let email: String 
    let mobile: String 
    let city: String 
    let state: String 
    let district: String 
    let area: String 
    let image: String 
    let rating: String 

    init(dictionary: [String:Any]) { 
     self.id = dictionary["id"] as? String ?? "Default Id" 
     self.name = dictionary["name"] as? String ?? "Default name" 
     self.address = dictionary["address"] as? String ?? "Default address" 
     self.website = dictionary["website"] as? String ?? "Default website" 
     self.email = dictionary["email"] as? String ?? "Default email" 
     self.mobile = dictionary["mobile"] as? String ?? "Default mobile" 
     self.city = dictionary["city"] as? String ?? "Default city" 
     self.state = dictionary["state"] as? String ?? "Default state" 
     self.district = dictionary["district"] as? String ?? "Default district" 
     self.area = dictionary["area"] as? String ?? "Default area" 
     self.image = dictionary["image"] as? String ?? "Default image" 
     self.rating = dictionary["rating"] as? String ?? "Default rating" 
    } 
} 

现在，你只需要两个数组类型[Item]一个正常的数据，一个用于filter数据，因此声明两个数组这样。

var items = [Item]() 
var filterItems = [Item]() 

初始化你Alamofire要求该items阵列喜欢这种方式。

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

if let resData = response["data"].arrayObject as? [[String: Any]] { 
    self.items = resData.map(Item.init) 
} 

现在在tableView这个方法中使用这两个数组。现在

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    if searchActive { 
     return filterItems.count 
    } 
    return items.count 
} 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! YourCustomCell 
    let item = searchActive ? filterItems[indexPath.row] : items[indexPath.row] 
    cell.lblName.text = item.name 
    cell.lblAddress.text = item.address 
    //...Set others detail same way 
    return cell 
} 

与textDidChange筛选items阵列这种方式。

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
{ 
    filterItems = self.items.filter({ 
     $0.name.localizedCaseInsensitiveContains(searchText) 
    }) 

    if(filterItems.count == 0) { 
     searchActive = false 
    }    
    else { 
     searchActive = true 
     print("Search Array = \(filterItems)") 
    }   
    self.infoTableView.reloadData() 
}
