如何检查json对象的数组中的多个键相同的值？

我正在使用Swift3在日历上工作。 我知道可以为不同的键设置相同的值。

我有这个名为Dictionary of JSON objects的NSArray ：

 if parsedData["status"] as! Int == 200 { if let Streams = parsedData["data"] as! [AnyObject]? { for Stream in Streams { print(Stream) } Stream result: { "-" = 4; 1 = X; 10 = H; 11 = X; 12 = X; 13 = X; 14 = X; 15 = X; 16 = X; 17 = H; 18 = X; 19 = X; 2 = X; 20 = X; 21 = X; 22 = X; 23 = L; 24 = H; 25 = X; 26 = L; 27 = "-"; 28 = "-"; 29 = "-"; 3 = H; 30 = "-"; 4 = X; 5 = X; 6 = X; 7 = X; 8 = X; 9 = X; H = 4; L = 2; X = 20; blank = ""; classid = id; classname = " (A)"; stdid = 1; stdnm = "name"; } 

这里1到31是依赖于月份的常量天数。 XHL是叶子，正常叶子和正常。 我需要检查x，h，l值和获取date。

但是，我不知道确切的逻辑来检查值是否相同，然后将其值添加到相同的密钥。

请帮帮我。 感谢您

请检查 ：

这是你的JSON格式

 if let streams = parsedData["data"] as! [AnyObject]? { for stream in streams { let dict = stream as? [AnyHashable: Any] print(getValue(key: "H", dict: dict!)) print(getValue(key: "L", dict: dict!)) print(getValue(key: "X", dict: dict!)) } } func getValue(key: String, dict: [AnyHashable: Any]) -> [Int] { return dict.filter { $0.value as? String == key }.flatMap { Int(String(describing: $0.key)) } } 

以下是字典

 let dict = ["-": 4, 1: "X", 10: "H", 11: "X", 12: "X", 13: "X", 14: "X", 15: "X", 16: "X", 17: "H", 18: "X", 19: "X", 2: "X", 20: "X", 21: "X", 22: "X", 23: "L", 24: "H", 25: "X", 26: "L", 27: "-", 28: "-", 29: "-", 3: "H", 30: "-", 4: "X", 5: "X", 6: "X", 7: "X", 8: "X", 9: "X", "H": 4, "L": 2, "X": 20] as [AnyHashable : Any] 

选项1通过密钥并将返回date数组

  print(getValue(key: "H", dict: dict)) //[17, 10, 24, 3] print(getValue(key: "L", dict: dict)) //[26, 23] print(getValue(key: "X", dict: dict)) //[12, 25, 14, 20, 5, 15, 7, 11, 13, 16, 19, 22, 21, 9, 18, 2, 6, 4, 1, 8] func getValue(key: String, dict: [AnyHashable: Any]) -> [Int] { return dict.filter { $0.value as? String == key }.flatMap { $0.key as? Int} } 

选项2传递多个键，并返回与每个键相关的date数组的字典

  print(getValue2(keys: ["H","L","X"], dict: dict)) //["H": [17, 24, 3, 10], "L": [23, 26], "X": [14, 20, 13, 19, 21, 9, 6, 1, 12, 25, 5, 15, 7, 11, 16, 22, 18, 2, 4, 8]] func getValue2(keys: [String], dict: [AnyHashable: Any]) -> [String: [Int]] { var returnValue = [String: [Int]]() for key in keys { returnValue[key] = [Int]() } dict.forEach { if let v = $0.value as? String, returnValue[v] != nil, let k = $0.key as? Int { returnValue[v]!.append(k) } } return returnValue }
