如何在同一个键

Question

我有一个字典数组，我想获取具有这些值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"}]

Answer 1

[NSPredicate predicateWithFormat：@＆＃34;分区IN％@＆＃34;，@ [@＆＃34; D1＆＃34;，@＆＃34; D12＆＃34;，@＆＃34; D14＆＃ 34]

Answer 2

var resultPredicate:NSPredicate = NSPredicate()

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