获取json数组时遇到问题。
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"
}
]
以上json有2个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: Error Domain = JSONModelErrorDomain Code = 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'。}
我无法找到错误的地方......任何人都可以建议正确使用JsonModel
并正确解析jsonString到TSCard
个对象的数组。

尝试使用以下代码解析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;
或者您需要更改您的JSONString,如下所示
{
"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"
}
]
}
比你的代码肯定会有效。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,您不必做任何其他事情或宣布任何协议:
@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,您可以使用一条整齐的短线来获取阵列:
NSArray *dataArray = [BWJSONMatcher matchJSON:jsonString withClass:[TSCard class]];

您可以在JSONModel
NSError *error;
NSMutableArray <TSCard *> *yourArray = [TSCard arrayOfModelsFromString:strData error:&error];
并按照你的逻辑行事。
