Question

以下是我的回复格式：

[
  {
    "id": 9001,
    "name": "A to B",
    "description": "A to B via mooncity",
    "sequence":[
      1001,
      1002,
      1003
      ]
  },
 {
    "id": 9002,
    "name": "B to D",
    "description": "B to D via suncity",
    "sequence":[
      1010,
      1002,
      1009
      ]
  }
]

现在，我希望将1002中包含sequence array的所有词典添加到另一个数组中。

我累了

NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"%K contains[c] %@", @"sequence", @"1002"];

但是上面的谓词适用于字典数组。虽然在这种情况下无效。

非常感谢任何帮助。

Answer 1

在swift中它对我有用

let array = ["101","110","133"]
    let dict = ["sequence":array,"id": "10"] as [String : AnyObject]

    let array1 = ["100","110","133"]
    let dict1 = ["sequence":array1,"id": "10"] as [String : AnyObject]

    let fArray : NSArray = [dict,dict1] as NSArray


    let pred = NSPredicate(format:  "ANY self.sequence contains[c] %@", "100")

    let test = fArray.filteredArrayUsingPredicate(pred)

    print(test)

out put

[{
id = 10;
sequence =     (
    100,
    110,
    133
);

}]

Answer 2

 NSPredicate *pred = [NSPredicate predicateWithFormat:@"CAST(sequence, 'NSString') contains[cd] %@", @"1002"];
 NSArray *result = [your_array filteredArrayUsingPredicate:pred];

在Array of Dictionaries中搜索值
