从NSArray中检索NSDictionary，其中字典键的值为X. [英] Retrieve NSDictionary from NSArray where dictionary key has value X

问题描述

我有 NSArray ， NSDictionaries 。其中一个数组中的一个字典键包含一个值。我想检索带有该值的 NSDictionary 。

I have an NSArray with NSDictionaries. One of the dictionaries keys in one of the arrays contains a value. I want to retrieve the NSDictionary with that value.

我的数组：

Array: (
        {
        DisplayName = "level";
        InternalName = "Number 2";
        NumberValue = 1;
    },
        {
        DisplayName = "PurchaseAmount";
        InternalName = "Number 1";
        NumberValue = 3500;
    }
)

所以，我想得到包含 DisplayName <的字典/ code>设置为 PurchaseAmount （不区分大小写）。

So, I would like to get the dictionary which contains DisplayName set to PurchaseAmount (case insensitive).

我该如何实现？

推荐答案

LIKE [cd]也会这样做

LIKE[cd] will also do it

NSArray *filtered = [data filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(DisplayName LIKE[cd] %@)", @"purchaseAmount"]];

返回

<NSArray>(
    {
       DisplayName = PurchaseAmount;
       InternaName = "Number 1";
       NumberValue = 3500;
    }
)
