我是 RestKit 和 Objective C 的新手。我正在尝试使用 RestKit 从 Web 服务中检索数据。我已经完成了映射，但有些我得到的错误是它找不到响应的匹配项。我使用没有 KVC 的映射，因为 JSON 格式没有密钥。
这是映射实现
+(RKObjectMapping *)venueMapping {
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[venue class]];
NSDictionary *mappingDictionary = @{@"name":@"name"};
[mapping addAttributeMappingsFromDictionary:mappingDictionary];
return mapping;
}
我正在尝试仅使用一个值来查看是否有任何匹配项。下面是响应描述符
-(void) loadVenue:(void (^)(venue *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure{
RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace);
[self getObjectsAtPath:@"venue" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult){
if(success){
venue *venues = (venue *)[mappingResult.array firstObject];
success(venues);
}
}failure:^(RKObjectRequestOperation *operation, NSError *error){
if(failure){
failure(operation,error);
}
}];
}
- (void) setupResponseDescriptors {
[super setupResponseDescriptiors];
RKResponseDescriptor *authenticatedUserResponseDescriptors = [RKResponseDescriptor responseDescriptorWithMapping:[MappingProvider venueMapping] method:RKRequestMethodGET pathPattern:@"venue" keyPath:@"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[self addResponseDescriptor:authenticatedUserResponseDescriptors];
}
我一直在阅读文档并尝试各种方法，但对此我仍然有零解决方案。有人有什么想法吗？
附件是一个示例 JSON 返回。
(
{
coverType = "<null>";
description = "";
name = "McDonald";
priv = 1;
rates = ();
},
{
coverType = "<null>";
description = "";
name = "My House";
priv = 1;
rates =();
},
)
添加了跟踪日志
