我有一个名为“Store”的主要实体类，例如:
Store.h:-
#import <Foundation/Foundation.h>
#import "SignIn.h"
@interface Store : NSObject
@property (nonatomic, retain) NSString *storeId;
@property (nonatomic, retain) NSString *storeProfileId;
@property (nonatomic, retain) NSString *storeName;
@property (nonatomic, retain) NSString *storeRegion;
@property (nonatomic, retain) SignIn *signIn;
@end
商店.m:-
#import "Store.h"
@implementation Store
@synthesize storeId, storeProfileId, storeName, storeRegion, signIn;
- (id) initWithCoder: (NSCoder *)coder
{
self = [[Store alloc] init];
if (self != nil)
{
self.storeId = [coder decodeObjectForKey:@"storeId"];
self.storeProfileId = [coder decodeObjectForKey:@"storeProfileId"];
self.storeName = [coder decodeObjectForKey:@"storeName"];
self.storeRegion = [coder decodeObjectForKey:@"storeRegion"];
self.signIn = [coder decodeObjectForKey:@"signIn"];
}
return self;
}
- (void)encodeWithCoder: (NSCoder *)coder
{
[coder encodeObject:storeId forKey:@"storeId"];
[coder encodeObject:storeProfileId forKey:@"storeProfileId"];
[coder encodeObject:storeName forKey:@"storeName"];
[coder encodeObject:storeRegion forKey:@"storeRegion"];
[coder encodeObject:signIn forKey:@"signIn"];
}
@end
在 Store 类中，我又采用了一个类名“Sign In”，其中包含一些其他属性。
SignIn.h:-
#import <Foundation/Foundation.h>
@interface SignIn : NSObject
@property (nonatomic, retain) NSString *inTime;
@property (nonatomic, retain) NSString *outTime;
@property (nonatomic, retain) NSString *isStatus;
@end
登录.m:-
#import "SignIn.h"
@implementation SignIn
@synthesize inTime, outTime, isStatus;
- (id) initWithCoder: (NSCoder *)coder
{
self = [[SignIn alloc] init];
if (self != nil)
{
self.inTime = [coder decodeObjectForKey:@"inTime"];
self.outTime = [coder decodeObjectForKey:@"outTime"];
self.isStatus = [coder decodeObjectForKey:@"isStatus"];
}
return self;
}
- (void)encodeWithCoder: (NSCoder *)coder
{
[coder encodeObject:inTime forKey:@"inTime"];
[coder encodeObject:outTime forKey:@"outTime"];
[coder encodeObject:isStatus forKey:@"isStatus"];
}
@end
现在我需要在服务器上发布这个 Store 对象。所以我使用下面的代码创建字典:
NSMutableArray *storeJSONArray=[NSMutableArray array];
for (Store *store in array1) {
NSMutableDictionary *storeJSON=[NSMutableDictionary dictionary];
[storeJSON setValue:store.storeId forKey:@"storeId"];
[storeJSON setValue:store.storeProfileId forKey:@"storeProfileId"];
[storeJSON setValue:store.storeName forKey:@"storeName"];
[storeJSON setValue:store.storeRegion forKey:@"storeRegion"];
//Sign In
[storeJSON setValue:store.signIn.inTime forKey:@"inTime"];
[storeJSON setValue:store.signIn.outTime forKey:@"outTime"];
[storeJSON setValue:store.signIn.isStatus forKey:@"isStatus"];
[storeJSONArray addObject:storeJSON];
}
NSMutableDictionary *dictionnary = [NSMutableDictionary dictionary];
[dictionnary setObject:storeJSONArray forKey:@"Store"];
NSError *error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary
options:kNilOptions
error:&error];
if (! jsonData) {
NSLog(@"Got an error: %@", error);
} else {
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
}
但作为输出，我得到的 jsonString 值如下:
{
"Store": [
{
"storeId": "SGVM0001",
"storeProfileId": "SG-12",
"store_name": "Best Denki",
"storeRegion": "Ngee Ann City",
"inTime": "2013-12-05 11:03:00",
"outTime": "2013-12-0511: 27: 00",
"isStatus": "YES"
}
]
}
但我需要一个输出:
{
"Store": [
{
"storeId": "SGVM0001",
"storeProfileId": "SG-12",
"store_name": "Best Denki",
"storeRegion": "Ngee Ann City",
"signIn": {
"inTime": "2013-12-05 11:03:00",
"outTime": "2013-12-0511: 27: 00",
"isStatus": "YES"
}
}
]
}
您能否检查我的代码并让我知道我需要在这里进行哪些更改才能获得上述输出？
谢谢
最佳答案
然后你需要再创建一本字典
NSDMutableDict *signInDic = [NSMutableDictionary dictionary];
//Sign In
[signInDic setValue:store.signIn.inTime forKey:@"inTime"];
[signInDic setValue:store.signIn.outTime forKey:@"outTime"];
[signInDic setValue:store.signIn.isStatus forKey:@"isStatus"];
[storeJSON setObject:signInDic forKey:@"sign_in"];
