使用 Django Rest Framework 设置 iOS Restkit

Question

我有一个 API，位于此网址：https://evening-everglades-1560.herokuapp.com/api/v1/stocks/

我正在尝试像这样实现iOS RestKit（这是在MasterViewController.m中）：

RKObjectMapping *stockMapping = [RKObjectMapping mappingForClass:[Stock class]];
[stockMapping addAttributeMappingsFromDictionary:@{@"stockId": @"id"}];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:stockMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"" statusCodes:statusCodes];

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://evening-everglades-1560.herokuapp.com/api/v1/stocks.json"]];
RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[responseDescriptor]];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
        Stock *stock = [result firstObject];
        NSLog(@"mapped w stock: %@", stock);
    } failure:^(RKObjectRequestOperation *operation, NSError *error) {
        NSLog(@"failed w error: %@", [error localizedDescription]);
    }];
[operation start];

这是记录的内容：

2016-01-17 16:42:08.233 Stocks[9415:1208281] W restkit.object_mapping:RKMapperOperation.m:99 Adding mapping error: No mappable values found for any of the attributes or relationship mappings

2016-01-17 16:42:08.235 Stocks[9415:1208245] mapped w stock: (null)`

我不确定要为

pathPattern

和

keyPath

放什么。

Answer 1

由于 wain 询问“您尚未给出对象定义”，该问题已得到修复。 我忘记在我的

stock.h

可可类中定义提交者。

将

@property(nonatomic, strong) NSString *submitter;

添加到 stock.h 修复了该问题。
