Ios 如何对同一键上的多个值使用nspredicate

我有一个字典数组，我想得到具有这些值D1，D12，D14的数据

例如：

[@{"district":"D1"}, {"district":"D2"}, {"district":"D2"}, {"district":"D12"}, {"district":"D15"}, {"district":"D14"}, {"district":"D14"}, {"district":"D12"}, {"district":"D1"}, {"district":"D18"}, {"district":"D17"}]

[NSPredicate谓词格式：@“地区在%@”，“D1”，“D12”，“D14”]

var resultPredicate:NSPredicate = NSPredicate()

resultPredicate = NSPredicate(format: "district = %@", ["D1","D12","D14"])
