ios – MOTIS对象映射,使用带有NSArray值的NSDictionary,如何指定数组元素的类型？

#import <Foundation/Foundation.h>

@interface Types: NSObject
@property (nonatomic,copy) NSDictionary *types;

@end

#import "Types.h"
#import <Motis/Motis.h>
#import "SubTipo.h"

@implementation Types
+ (NSDictionary*)mts_mapping
{
    return @{@"types": mts_key(types),};
}



@end

#import <Foundation/Foundation.h>

@interface Subtype: NSObject
@property (nonatomic,assign) int cve;
@property (nonatomic,copy) NSString *description;
@end

#import "Subtype.h"
#import <Motis/Motis.h>

@implementation Subtype
+ (NSDictionary*)mts_mapping
{
    return @{@"cve": mts_key(cvE),@"description": mts_key(description),};
}

@end

Types * values=[[Types alloc]init];
 NSDictionary * jsonObject = [NSJSONserialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];


    [values mts_SETVALuesForKeysWithDictionary:jsonObject ];

+ (NSDictionary*)mts_arrayClassmapping
{
    return @{mts_key(types): Subtype.class};
}

据我所知,您的Types对象未正确定义.如果您具有NSDictionary *类型的属性并且收到的JSON是字典,则Motis将不会执行任何自动转换,因为类型已经匹配(您正在接收字典,并且您的属性是NSDictionary类型).

因此,您必须遵循JSON结构实现Type对象.这意味着您的Type对象必须具有两个类型为array的属性,一个用于food,一个用于health.然后,使用@L_142_8@mts_arrayClassmapping,您可以将数组的内容类型指定为Subtype.

这里实施：

// ***** Type.h file ***** //

@interface Type: NSObject

@property (nonatomic,strong) NSArray *food;
@property (nonatomic,strong) NSArray *health;

@end

// ***** Type.m file ***** //

@implementation Type

+ (NSDictionary*)mts_mapping
{
    return @{@"food": mts_key(food),@"Health": mts_key(health),};
}

+ (NSDictionary*)mts_arrayClassmapping
{
    return @{mts_key(food): Subtype.class,mts_key(health): Subtype.class,};
}

@end

关于Subtype的实现,你的已经是正确的了.但是,您不应该使用属性名称描述,因为它已被NSObject使用：

// ***** Subtype.h file ***** //

@interface Subtype: NSObject

@property (nonatomic,assign) NSInteger cve;
@property (nonatomic,copy) NSString *theDescription;

@end

// ***** Subtypes.m file ***** //

@implementation Subtype

+ (NSDictionary*)mts_mapping
{
    return @{@"cve": mts_key(cvE),@"description": mts_key(theDescription),};
}

@end

最后,如上所示,您可以映射您的JSON,但首先您必须提取关键类型的“字典”,您将映射到“类型”模型对象.

// Get the json data
NSDictionary * jsonObject = [NSJSONserialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];

// Extract the JSON Dictionary of types.
NSDictionary *jsonType = [jsonObject objectForKey:@"Types"];

// Create a Type object 
Type *type = [[Type alloc] init];

// Map JSON contents to the type object with Motis
[type mts_SETVALuesForKeysWithDictionary:jsonType];

希望这可以解决您的问题.
