iOS 在jsonModel中如何获取嵌套数组的数据？
小弟的model定义如下：
@class cartitems;
@class giftItems;
@class specification;
@class promotions;
@interface THWShoppingCartModel : JSONModel
@property (nonatomic, assign) NSInteger discountPrice;//优惠立减
@property (nonatomic, assign) NSInteger quantity;//商品数量
@property (nonatomic, assign) NSInteger id;//ID
@property (nonatomic, assign) NSInteger effectiveQuantity;//有效商品数
@property (nonatomic, assign) NSInteger freightPrice;//运费
@property (nonatomic, assign) NSInteger effectivePrice;//有效金额
@property (nonatomic, strong) NSArray<giftItems*> *giftItems; //订单项
@property (nonatomic, strong) NSArray<cartitems*> *cartItems; //礼物项
@property (nonatomic, assign) NSInteger effectivePoint;//有效商品积分
@end
@interface cartitems : JSONModel
@property (nonatomic, assign) NSString* id; //订单ID
@property (nonatomic, assign) NSString *productId; //shangpinID
@property (nonatomic, copy) NSString *unit;//单位
@property (nonatomic, assign) NSString *quantity; //数量
@property (nonatomic, assign) NSString *discount;//折扣金额
@property (nonatomic, copy) NSString *tenantName;//商家名称
@property (nonatomic, copy) NSString *tenantId;//商家ID
@property (nonatomic, assign) NSString *price;//折后单价
@property (nonatomic, assign) NSString *subTotal;//金额小计
@property (nonatomic, copy) NSString *fullName;//全名
@property (nonatomic, copy) NSString *thumbnail;//缩略图
@property (nonatomic, strong) NSArray<specification*> *specification; //促销
@property (nonatomic, strong) NSArray<promotions*> *promotions; //规格
@property (nonatomic, assign) BOOL selected; //是否选择
@property (nonatomic, copy) NSString *name;//规格值
@property(nonatomic,copy) NSString *coupon;//是否可领卷
@end
@interface giftItems : JSONModel
@property(copy,nonatomic)NSString *id ; //ID
@property (nonatomic, assign) NSUInteger productId ; //商品Id
@property(copy,nonatomic)NSString * fullName; //全名
@property(copy,nonatomic)NSString *unit; //单位
@property(copy,nonatomic)NSString *thumbnail; //缩略图
@property(copy,nonatomic)NSString *quantity; //数量
@end
@interface specification : JSONModel
@property (nonatomic, assign) NSUInteger id; //规格Id
@property(copy,nonatomic)NSString *name; //规格名称
@end
@interface promotions : JSONModel
@property (nonatomic, assign) NSUInteger id; //促销Id
@property(copy,nonatomic)NSString *name; //促销名称
@end
现在需要用：
-(void)parseShoppingCartModelProfile:(NSArray*) cartItems
{
if(!_moduleDic)
_moduleDic = [NSMutableDictionary new];
for (cartitems *item in cartItems) {
@try {
NSString *tentid = [NSString stringWithFormat:@"%@",item.tenantId];
if(![_moduleDic.allKeys containsObject:tentid])
{
[_moduleDic setValue:item forKey:tentid];
}
else
{
[((NSMutableArray *)_moduleDic[tentid]) addObject:item];
}
} @catch (NSException *exception) {
NSLog(@"%@",exception.description);
}
}
}这个方法获取循环遍历处理THWShoppingCartModel NSArray<cartitems> cartItems 中每个成员的数据，但是无论如何都获取不到item.tenantId和其他cartItems model的数据，总是提示： -[__NSCFDictionary tenantId]: unrecognized selector sent to instance 0x7fdf9e0a3fa0，请问大神门如何处理？
