获取 json 数组时遇到问题。

我正在使用 JsonModel 库进行 json 处理。

我的json数据是：

[
    {
        "TSCard_id": 100,
        "TSCardBackend_id": "TSu1t1",
        "TSCard_date": "10/11/2013",
        "TSCard_resource_id": "",
        "TSCard_resource_name": "",
        "TSCard_job_id": "JOB_M2156 ",
        "TSCard_job_desc": "BAGARIA MILLIPORE - BOM ",
        "TSCard_activity_id": "B03",
        "TSCard_activity_desc": "Closing",
        "TSCard_hours": "4.0",
        "TSCard_chargeableflag": "0",
        "TSCard_desc": "Description:",
        "TSCard_syncflag": "0",
        "TSCard_flag": "",
        "user_id": "1"
    },
    {
        "TSCard_id": 101,
        "TSCardBackend_id": "TSu1t2",
        "TSCard_date": "12/11/2013",
        "TSCard_resource_id": "",
        "TSCard_resource_name": "",
        "TSCard_job_id": "JOB_B0002",
        "TSCard_job_desc": "ABB LIMITED - BLR ",
        "TSCard_activity_id": "NB01",
        "TSCard_activity_desc": "Admin  ",
        "TSCard_hours": "5.0",
        "TSCard_chargeableflag": "1",
        "TSCard_desc": "Description:",
        "TSCard_syncflag": "0",
        "TSCard_flag": "",
        "user_id": "1"
    }
]

上面的json有2个类型的对象TSCard class

 //TSCard.h
#import <Foundation/Foundation.h>
#import <JSONModel.h>

@protocol TSCard @end

@interface TSCard : JSONModel

@property (nonatomic, retain) NSString  *TSCard_id;
@property (nonatomic, retain) NSString  *TSCardBackend_id;

@property (nonatomic, retain) NSString  *TSCard_date;
@property (nonatomic, retain) NSString  *TSCard_resource_id;
@property (nonatomic, retain) NSString  *TSCard_resource_name;
@property (nonatomic, retain) NSString  *TSCard_job_id;
@property (nonatomic, retain) NSString  *TSCard_job_desc;
@property (nonatomic, retain) NSString  *TSCard_activity_id;
@property (nonatomic, retain) NSString  *TSCard_activity_desc;
@property (nonatomic, retain) NSString  *TSCard_hours;
@property (nonatomic, retain) NSString  *TSCard_chargeableflag;
@property (nonatomic, retain) NSString  *TSCard_desc;
@property (nonatomic, retain) NSString  *TSCard_syncflag;
@property (nonatomic, retain) NSString  *TSCard_flag;
@property (nonatomic, retain) NSString  *user_id;

@end

我正在为类型数组创建一个类TSCard

 //GetCardData.h

#import <JSONModel.h>
#import "TSCard.h"


@interface GetCardData : JSONModel

@property(strong,nonatomic)NSArray<TSCard>* myDataArray;

@end

然后我解析json如下：

NSError* err = nil;
GetCardData *c = [[GetCardData alloc] initWithString:jsonString error:&err];

    NSLog(@"%d",c.myDataArray.count);

NSLog 错误：错误域 = JSONModelErrorDomain 代码 = 1“无效的 JSON 数据：尝试使用 initWithDictionary 初始化 JSONModel 对象：错误：但字典参数不是 'NSDictionary'。” UserInfo=0x8265490 {NSLocalizedDescription=无效 JSON 数据：尝试使用 initWithDictionary 初始化 JSONModel 对象：错误：但字典参数不是“NSDictionary”。}

我找不到我错的地方......任何人都可以建议正确使用JsonModeljsonString并将其解析为TSCard对象数组的正确方法。

尝试使用以下代码解析您的 json 并获取数组

NSMutableArray *yourArray = [TSCard arrayOfModelsFromDictionaries:jsonString];

比创建和分配

GetCardData *objCardData = [[GetCardData alloc] init];
objCardData.myDataArray = yourArray;

或者你需要改变你的 JSONString 如下

   {
    "myDataArray": [
        {
            "TSCard_id": 100,
            "TSCardBackend_id": "TSu1t1",
            "TSCard_date": "10/11/2013",
            "TSCard_resource_id": "",
            "TSCard_resource_name": "",
            "TSCard_job_id": "JOB_M2156 ",
            "TSCard_job_desc": "BAGARIA MILLIPORE - BOM ",
            "TSCard_activity_id": "B03",
            "TSCard_activity_desc": "Closing",
            "TSCard_hours": "4.0",
            "TSCard_chargeableflag": "0",
            "TSCard_desc": "Description:",
            "TSCard_syncflag": "0",
            "TSCard_flag": "",
            "user_id": "1"
        },
        {
            "TSCard_id": 101,
            "TSCardBackend_id": "TSu1t2",
            "TSCard_date": "12/11/2013",
            "TSCard_resource_id": "",
            "TSCard_resource_name": "",
            "TSCard_job_id": "JOB_B0002",
            "TSCard_job_desc": "ABB LIMITED - BLR ",
            "TSCard_activity_id": "NB01",
            "TSCard_activity_desc": "Admin  ",
            "TSCard_hours": "5.0",
            "TSCard_chargeableflag": "1",
            "TSCard_desc": "Description:",
            "TSCard_syncflag": "0",
            "TSCard_flag": "",
            "user_id": "1"
        }
    ]
}

比你的代码肯定会工作。告诉我是否需要更多帮助。

对于您的问题，我个人推荐BWJSONMatcher。除了数据模型之外，您无需执行任何其他操作或声明任何协议：

@interface TSCard : NSObject

@property (nonatomic, strong) NSString  *TSCard_id;
@property (nonatomic, strong) NSString  *TSCardBackend_id;

@property (nonatomic, strong) NSString  *TSCard_date;
@property (nonatomic, strong) NSString  *TSCard_resource_id;
@property (nonatomic, strong) NSString  *TSCard_resource_name;
@property (nonatomic, strong) NSString  *TSCard_job_id;
@property (nonatomic, strong) NSString  *TSCard_job_desc;
@property (nonatomic, strong) NSString  *TSCard_activity_id;
@property (nonatomic, strong) NSString  *TSCard_activity_desc;
@property (nonatomic, strong) NSString  *TSCard_hours;
@property (nonatomic, strong) NSString  *TSCard_chargeableflag;
@property (nonatomic, strong) NSString  *TSCard_desc;
@property (nonatomic, strong) NSString  *TSCard_syncflag;
@property (nonatomic, strong) NSString  *TSCard_flag;
@property (nonatomic, strong) NSString  *user_id;

@end

然后，您可以使用一条简洁的短线获得阵列：

NSArray *dataArray = [BWJSONMatcher matchJSON:jsonString withClass:[TSCard class]];

您可以在JSONModel

NSError *error;
NSMutableArray <TSCard *> *yourArray = [TSCard arrayOfModelsFromString:strData error:&error];

做你的逻辑。
