ios - 在Xcode或MODEL中创建数据访问对象

需要创建以下模型。
以下是来自Web服务响应的Json响应，

现在，我想创建它的模型，以便我们可以轻松地获取它，例如

EmployeeClass.status =
EmployeeClass.statusCode =
EmployeeClass.description =
EmployeeClass.employeeId =

EmployeeClass.Present =
EmployeeClass.Leave =
EmployeeClass.Absent =
EmployeeClass.PFCode=

我的JSON字符串是

{
    "EmployeeClass": {
        "responseStatus": {
            "status": "SUCCESS",
            "statusCode": "100",
            "description": "Success",
            "employeeId": "1011"
        },
        "Present": 22,
        "Leave": 1,
        "Absent": 4
    },
    "PFCode": "ABC123"
}

到目前为止我尝试过的

创建单例类EmployeeClass

//------.h class ----------------

#import < Foundation/Foundation.h >
@interface EmployeeClass : NSObject
@property (nonatomic, strong)NSString * status ;
@property (nonatomic, strong)NSString * statusCode ;
@property (nonatomic, strong)NSString * description ;
@property (nonatomic, strong)NSString * employeeId ;

@property (nonatomic, strong)NSString * Present ;
@property (nonatomic, strong)NSString * Leave ;
@property (nonatomic, strong)NSString * Absent ;
@property (nonatomic, strong)NSString * PFCode;

+ (EmployeeClass*)sharedSingleton;
@end

//----------.m类-----------

#import "EmployeeClass.h"

@implementation EmployeeClass
- (id)init {
    self = [super init];

    if(self) {


        self.status = [NSString new];
        self.statusCode = [NSString new];
        self.description = [NSString new];
        self.employeeId = [NSString new];
        self.Present = [NSString new];
        self.Leave = [NSString new];
        self.Absent = [NSString new];
        self.PFCode = [NSString new];


        //do any more customization to your location manager
    }

    return self;
}
+ (EmployeeClass *)sharedSingleton {
    static EmployeeClass *sharedSingleton;
    @synchronized(self) {
        if (sharedSingleton == nil) {
            sharedSingleton = [[EmployeeClass alloc] init];
        }
    }
    return sharedSingleton;
}



@end

最佳答案

我不知道我是否正确理解了您的问题，但是您不应该执行EmployeeClass.property =之类的操作，因为您正试图访问存储在CLASS中的某些属性，但这没有任何意义。您必须访问该类的实例。

因此，首先您必须检索单例的实例：EmployeeClass *obj = [EmployeeClass sharedSingleton];，然后可以访问对象的属性：obj.status =

要解析JSON字符串，您可以执行以下操作：

NSError *error;
NSData *jsondata = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary respObj = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

因此，现在您有了包含所有属性的字典。要访问单个属性：[respObj valueForKey:@"anyKey"];。例如obj.status = [respObj valueForKey:@"EmployeeClass"] valueForKey:@"responseStatus"] valueForKey:@"status"]。这是因为第一个和第二个“ valueForKey”消息将返回另一个NSDictionary。

希望这可以帮助。
