我想将上述数组与＆＃34; services＆＃34;进行比较。来自第一个数组的键和＆＃34; sub_cat_id＆＃34;从第二个数组开始，最后打印包含车辆的公共服务ID的price_per_unit。

示例 - 在第一个数组中找到的5923f21c2279518a1661cb09,5923f22d2279513f1861cb09以便从第二个数组中打印两个ID的price_per_units - 30,45

让它在游乐场工作：

let booking: [String: Any] = [
    "services": "5923f21c2279518a1661cb09,5923f22d2279513f1861cb09",
    "status":2
]

let selectedServices: [[String: Any]] = [
    [
        "price_per_unit": 30,
        "sub_cat_id": "5923f21c2279518a1661cb09",
        "sub_cat_name": "SUV",
        "unit": 1
    ],
    [
        "price_per_unit": 45,
        "sub_cat_id": "5923f22d2279513f1861cb09",
        "sub_cat_name": "Sedan",
        "unit": 1
    ],
    [
        "price_per_unit": 65,
        "sub_cat_id": "5923f23e2279518a1661cb09",
        "sub_cat_name": "Bus",
        "unit": 1
    ],
    [
        "price_per_unit": 75,
        "sub_cat_id": "5923f24f2279513f1861cb09",
        "sub_cat_name": "Lorry",
        "unit": 1
    ]
]

if let bookingServices = booking["services"] as? String {
    let services: [String] = bookingServices.components(separatedBy: ",")

    let commonServices = selectedServices.filter({ services.contains( $0["sub_cat_id"] as? String ?? "" ) })
    print(commonServices)
}

Objective-C等价物：

NSDictionary *booking = @{
                                @"services": @"5923f21c2279518a1661cb09,5923f22d2279513f1861cb09",
                                @"status": @2
                                };

NSArray *selectedServices =  @[
             @{
              @"price_per_unit": @30,
              @"sub_cat_id": @"5923f21c2279518a1661cb09",
              @"sub_cat_name": @"SUV",

              },
             @{

              @"unit": @1
              },
             @{

              @"sub_cat_id": @"5923f23e2279518a1661cb09",
              @"sub_cat_name": @"Bus",
              @"unit": @1
              },
             @{

              }
             ];

NSString *servicesString = [booking valueForKey: @"services"];
NSArray *bookingServices = [servicesString componentsSeparatedByString:@","];

NSMutableArray *commonServices = [[NSMutableArray alloc] init];

for (NSDictionary *selectedService in selectedServices) {
    NSString *sub_cat_id = selectedService[@"sub_cat_id"];

    if([bookingServices containsObject: sub_cat_id]) {
        [commonServices addObject: selectedService];
    }
}

NSLog(@"%@", commonServices);

我认为你应该使用NSPredicate，因为这是快速枚举。只需两行代码

我在这里使用你的演示内容。

NSDictionary *maindic = @{@"price_per_min" :@"10",
                                   @"services":@"5923f21c2279518a1661cb09,5923f22d2279513f1861cb09",
                                  };

    NSDictionary *dic1 =@{@"price_per_unit" :@"30",
                           @"sub_cat_id":@"5923f21c2279518a1661cb09",
                           };

    NSDictionary *dic2 =@{@"price_per_unit" :@"45",
                           @"sub_cat_id":@"5923f22d2279513f1861cb09",
                           };
    NSDictionary *dic3 =@{@"price_per_unit" :@"65",
                          @"sub_cat_id":@"5923f23e2279518a1661cb09",
                          };

    NSArray *mainArr=  @[dic1,dic2,dic3];

    NSPredicate *predicate1 = [NSPredicate predicateWithFormat:@"sub_cat_id == '5923f21c2279518a1661cb09'"];
    NSPredicate *predicate2 = [NSPredicate predicateWithFormat:@"sub_cat_id == '5923f22d2279513f1861cb09'"];
    NSPredicate *predicate = [NSCompoundPredicate orPredicateWithSubpredicates:@[predicate1, predicate2]];

    NSArray *resultArray = [mainArr filteredArrayUsingPredicate:predicate];

，它将在resultArray中返回

{
    "price_per_unit" = 30;
    "sub_cat_id" = 5923f21c2279518a1661cb09;
},
{
    "price_per_unit" = 45;
    "sub_cat_id" = 5923f22d2279513f1861cb09;
}

如何从两个不同的数组中找到公共对象并打印另一个对象？
