Ios 如何从NSDictionary键加载NSMutableArray

我想将@“Color”、@“size”、@“Product_Img”键的值添加到不同键的不同NSMutable数组中

我的词典结构是……

{
Color =     (
            {
        "color_name" = Red;
        id = 1;
    },
            {
        "color_name" = Black;
        id = 2;
    },
            {
        "color_name" = white;
        id = 3;
    },
            {
        "color_name" = Pink;
        id = 4;
    },
            {
        "color_name" = Green;
        id = 5;
    }
);
"Product_Img" =     (
            {
        "product_image" = "15131445991.jpg";
        "product_image_id" = 94;
    }
);
"product_type" = product;
size =     (
            {
        size = "6 Kg";
    },
            {
        size = "7 Kg";
    },
            {
        size = "8 Kg";
    },
            {
        size = "9 Kg";
    }
);

[self.arrProductImageList removeAllObjects];
[self.arrProductImageList addObjectsFromArray:[_dictProductDetails objectForKey:@"Product_Img"]];

[self.arrProductColorList removeAllObjects];
[self.arrProductColorList addObjectsFromArray:[_dictProductDetails objectForKey:@"Color"]];

[self.arrProductSizeList removeAllObjects];
[self.arrProductSizeList addObjectsFromArray:[_dictProductDetails objectForKey:@"size"]];

}

我的代码就是我试图实现的

viewDidLoad

self.arrProductSizeList = [NSMutableArray array];
self.arrProductColorList = [NSMutableArray array];
self.arrProductImageList = [NSMutableArray array];

在配置数据方法中…

{
Color =     (
            {
        "color_name" = Red;
        id = 1;
    },
            {
        "color_name" = Black;
        id = 2;
    },
            {
        "color_name" = white;
        id = 3;
    },
            {
        "color_name" = Pink;
        id = 4;
    },
            {
        "color_name" = Green;
        id = 5;
    }
);
"Product_Img" =     (
            {
        "product_image" = "15131445991.jpg";
        "product_image_id" = 94;
    }
);
"product_type" = product;
size =     (
            {
        size = "6 Kg";
    },
            {
        size = "7 Kg";
    },
            {
        size = "8 Kg";
    },
            {
        size = "9 Kg";
    }
);

[self.arrProductImageList removeAllObjects];
[self.arrProductImageList addObjectsFromArray:[_dictProductDetails objectForKey:@"Product_Img"]];

[self.arrProductColorList removeAllObjects];
[self.arrProductColorList addObjectsFromArray:[_dictProductDetails objectForKey:@"Color"]];

[self.arrProductSizeList removeAllObjects];
[self.arrProductSizeList addObjectsFromArray:[_dictProductDetails objectForKey:@"size"]];

NSLog

NSLog(@"Size Array List%@", _arrProductSizeList);
NSLog(@"Color Array List%@", _arrProductColorList);
NSLog(@"Image Array List%@", _arrProductImageList);

提前感谢

也许您可以尝试以下代码：

---

self.arrProductSizeList=[[u dictProductDetails[@“Product\u Img”]mutableCopy] self.arrProductColorList=[[u dictProductDetails[@“Color”]mutableCopy] self.arrProductImageList=[[u dictProductDetails[@“size”]mutableCopy]

[_dictProductDetailsvalueforkey:@“产品”Img]；试一下这个不起作用比试一下下面的代码还有什么不起作用？你的结果应该是什么样的？我想要这个。。。大小数组列表（{Size=“6”}，{Size=“7”}，{Size=“8”}，{Size=“9”}）使用您获得的当前日志（即当前结果）编辑您的问题，实际上，在我的项目中，当我从同一个viewcontroller中的web服务加载_dictProductDetailsDictionary时，它会显示上面的结果，当我从另一个viewcontroller加载同一个dictionary时，我可以检索所有值和键，但加载arraysAlert消息的问题会显示出来“声誉低于15%的人所投的票将重新编码”
