Object Mapping in RestKit
我有一个这种格式的 JSON 响应
1 2 3 4 5 6 7 8 | {"status": { "id":0, "offerList":[{"offerId":38,"title":"TITLE OFFER 38","shortDescription":"OFFER PCT 38","orginalPrice":100,"image":"offer-38.jpg","description":"DESCRIPTION OFFER 38","shopId":4,"startDate":"5/29/2011 12:00:00 AM","endDate":"8/10/2011 12:00:00 AM","startTime":"16:30:00","endTime":"21:59:59","insertionDate":"7/5/2011 4:42:40 AM","categoryId":0,"subCategoryId":0,"published":1} "shopList":[{"id":4,"name":"Store 1","street":"Street Store 1","postCode":"88214","city":"Barcelona","state":"","country":"Spain, Kingdom of","description":"Loc Description Store 1","url":"http://www.store-1.com","email":"[email protected]","telephone":"Phone-number-store-1","published":1,"lastUpdated":"7/5/2011 4:42:40 AM","latitude":41.4398,"longitude":2.1601}] } } |
我正在使用 restkit 进行对象映射。使用 RKManaged Object 映射此 JSON 的可能方法是什么。
有人可以帮忙吗。我被困了3天。
谢谢
Zach,您可能应该在 RestKit 邮件列表中提出这个问题,并更具体地说明您想要实现的目标。
不管怎样,RestKit 作者 Blake Watters 刚刚发布了一个描述对象映射的新文档,它应该可以回答您的所有问题。祝你好运!
也许这无济于事,但我遇到了一个问题,即在尝试映射我的对象时 RestKit 崩溃了,问题是我试图将一个值映射到 keypath 'description'。这是不可行的,因为 'description' 是 Objective-C 中的一个关键字。尝试将该名称更改为其他名称。
扎克,
JSON 中对应映射的名称是什么,都称为 keyPath。
使用带有新对象映射的 RestKit 0.9.2:
我假设您需要从 Status(父)到 Offers 和 Shops(子)的一对多关系,并且属性名称在这里有点隐含。
通常在您的应用委托中,您可以像这样配置映射:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | RKObjectMapping* statusMapping = [RKObjectMapping mappingForClass:[Status class]]; [statusMapping mapKeyPathToAttributes:@"statusId",@"id"] // This maps JSON status.id to objc Status.statusId RKObjectMapping* offerMapping = [RKObjectMapping mappingForClass:[Offer class]]; // Add more pairs as needed in the line below [offerMapping mapKeyPathToAttributes:@"offerId",@"offerId",@"title",@"title",@"shortDescription",@"shortDescription"]; //Do the same thing for your Shop mapping //Configure relationships: //Assumes Status class has a property of type NSArray* offers that will contain multiple orders [statusMapping mapKeyPath:@"orderList" toRelationship:@"orders" withObjectMapping:offerMapping]; //Do the same thing for your Shop relationship |
问候,
