私は1つのURLからいくつかのデータを取得しており、私はテーブルビューで表示しようとしています。その前に私はすべての配列、検索、並べ替えを直接使用しました。それはうまくいきました。しかし今、私は私のテーブルビューのために別のクラスを作成するときこのエラーが表示されますタイプ 'BusinessData'にはメンバー 'sortUsingComparator'がありません
Type 'BusinessData' has no member 'sortUsingComparator'私の並べ替えのfunction.Here私は3ボタンアクションを与えた。そのボタンアクションの中でこのソートコードを宣言しています。しかし、今私はこのエラーが発生しています。
私bussinessData.swiftクラス
import UIKit
class BusinessData {
var BusinessName: String?
var Address: String?
var Rating: Float?
var ContactNumber: String?
init(json: NSDictionary) {
self.BusinessName = json["business_name"] as? String
self.Address = json["location"] as? String
self.Rating = json["__v"] as? Float
self.ContactNumber = json["phone_no"] as? String
}
}
マイviewcontroller.swiftコード：私はこれを取得していますすべての方法では
@IBAction func sortByAZBtnPress(sender: AnyObject)
{
RightMenu.hidden = true
BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in
if let name1 = dict1["business_name"] as? String, name2 = dict2["business_name"] as? String
{
return name1.compare(name2)
}
return .OrderedAscending
}
self.tableView.reloadData()
}
@IBAction func sortByRatingBtnPress(sender: AnyObject)
{
RightMenu.hidden = true
BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in
if let name1 = dict1["rating"] as? String, name2 = dict2["rating"] as? String
{
return name2.compare(name1)
}
return .OrderedDescending

私はこの中で、これらのボタンのアクションメソッドをエラーを取得していますエラーType 'BusinessData' has no member 'sortUsingComparator' ..これ以下の行に：
BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in
おかげ
あなたはクラスではなくオブジェクトで関数を呼び出すように見えますか？それは意図的なのでしょうか？あなたはarrDictを並べ替える気がしますか？ – Mattias
申し訳ありませんがあなたを得る？ – user5513630
ワインのより徹底的な答えと同じです:) – Mattias
