Ios 如何在swift 3.1.1中为搜索栏使用getter setter方法？

我已经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、图像、地址、手机号码、电子邮件）。我将在搜索结果中获取名称，但我希望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。提前谢谢

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中显示 如果（搜索活动） { 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]
    }

与使用多个数组来存储每个值不同，您需要的是自定义

类/结构

对象的数组，然后它就可以方便地使用

过滤器

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"
    }
}

现在您只需要两个

[Item]

类型的数组，一个用于普通数据，另一个用于

过滤器

数据，所以像这样声明两个数组

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

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
}

在您的

Alamofire

请求中，以这种方式初始化此

项

数组

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

方法中使用这两个数组，如下所示

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

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
}

现在，使用

textDidChange

以这种方式过滤

项

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()
}

你能告诉代码你是如何得到这个
JSON``数据的，以及你是如何在
tableView`@NiravD:：：使用alamofire，我从JSON得到响应，我将它存储在不同的数组中，并在tableView的标签中按行打印它们。self.nameArr是名称数组。你能展示一下你的一些示例吗？这会让我们知道你正在从
JSON
@NiravD Alamofire.request（url）.responseJSON{response in if let JSON=response.result.value访问什么密钥{let responseRes=JSON as？如果let resData=responseRes？[“data”]as？[AnyObject]{self.arrResponse=resData as！[[String:AnyObject]]用于self.arrResponse{et name=item[“name”]as！String self.arrName.append（name）}}}}不要在注释中添加代码编辑您的问题并用它编码一切正常。谢谢您的帮助。！！编码愉快。@A21欢迎伴侣：）
