ios - 在NSArray(iOS)中查找包含特定值的NSDictionary

Question

我有多个NSArray的NSDictionary(“address_components”)。每个NSDictionary包含一个NSArray值的NSString(“类型”)。像这样..

"address_components" =         (
{
    "long_name" = "Perumbavoor Puthencruz Road";
    "short_name" = "Perumbavoor Puthencruz Rd";
    types =                 (
        route
    );
},
{
    "long_name" = Vengola;
    "short_name" = Vengola;
    types =                 (
        locality,
        political
    );
},
{
    "long_name" = Ernakulam;
    "short_name" = EKM;
    types =                 (
        "administrative_area_level_2",
        political
    );
},
{
    "long_name" = Kerala;
    "short_name" = KL;
    types =                 (
        "administrative_area_level_1",
        political
    );
},
{
    "long_name" = India;
    "short_name" = IN;
    types =                 (
        country,
        political
    );
},
{
    "long_name" = 683556;
    "short_name" = 683556;
    types =                 (
        "postal_code"
    );
}
);

如何获得包含带有字符串“locality”的数组的字典。在此示例中，我想获取字典。

{
  "long_name" = Vengola;
  "short_name" = Vengola;
   types =(
      locality,
      political
   );
}

谢谢 :)

您需要像这样predicate您的地址数组

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY types CONTAINS[c] %@", @"locality"];
NSArray *arr = [yourArray filteredArrayUsingPredicate:predicate];
