ios - 如何从 objective-c 中的NSMutablearray中删除空值？

当我使用json Web服务并将值存储在NSMutablearray中时，却得到了Null响应。现在我想删除该null值并将其替换为空。任何人都可以帮助我解决此错误。

(
        {
        Aadhar =1123323244;
        AddressProofCopy = "<null>";
        Advertisement = "<null>";
        AgreementCopy = "<null>";
        ApCity = ggg;
        ApDistrict = g;
        ApDoorNo = g;
        ApFGFirstName = v;
        ApFGSurName = g;
        ApGender = F;
        ApPIN = 12323;
        ApStreet = h;
        AppStatus = "<null>";
        ApplRefStageStatus = N;
        ApplicantFirstName = g;
        ApplicantPhoto = "<null>";
        ApplicantSurName = g;
        ApplicationDate = "2018-09-06T00:00:00.000Z";
        ApplicationType = New;
        BuldingType = "<null>";
        District = 132424;
        DistrictId = 11;
        DocVerifiedBy = "<null>";
        DocVerifiedDate = "<null>";
        DocVerifiedMessage = "<null>";
        DocVerifiedStatus = "<null>";
    }
)

最佳答案

请验证此链接。https://github.com/bismasaeed00/NullReplacer它对我来说工作正常。

尝试这个..

#import "NSArray+NullReplacement.h"
#import "NSDictionary+NullReplacement.h"

之后，根据您的字典/数组JSON响应，使用以下代码行，

NSArray *newvalue = [yourarrayresponse arrayByReplacingNullsWithBlanks];

要么

NSDictionary *newvalue = [yourdictionary dictionaryByReplacingNullsWithBlanks];

如果您遇到任何错误，只需添加

#import "NSArray+NullReplacement.h"

在NSDictionary + NullReplacement类和

#import "NSDictionary+NullReplacement.h"

在NSDictionary + NullReplacement类文件中。
