我尝试按以下格式发布信息：
{
"meetingType": 1,
"startDate": "2011-05-26T07:56:00.123Z",
"recipientId": "useme",
"comment": "haha",
"activities": [
{"activityType": "walking", "startTime": "2011-05-26T07:00:00.123Z", "name":"someTrail", "address":"New York", "customData":"someData"},
{"activityType": "hiking", "startTime": "2011-05-26T07:30:00.123Z", "name":"Park", "address":"New York", "customData": {"someVar":"someData"} }
]
}
我有两个实体：Meeting＆amp; Activity Meeting与to-many
Activity的关系
App Delegate：
- (RKManagedObjectStore *)setupCoreDataWithRESTKit
{
NSError * error;
NSURL * modelURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"App" ofType:@"momd"]];
NSManagedObjectModel * managedObjectModel = [[[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL] mutableCopy];
self.managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel];
[self.managedObjectStore createPersistentStoreCoordinator];
NSArray * searchPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * documentPath = [searchPaths objectAtIndex:0];
NSPersistentStore * persistentStore = [self.managedObjectStore addSQLitePersistentStoreAtPath:[NSString stringWithFormat:@"%@/CoreData.sqlite", documentPath] fromSeedDatabaseAtPath:nil withConfiguration:nil options:nil error:&error];
if(!persistentStore){
NSLog(@"Failed to add persistent store: %@", error);
}
[self.managedObjectStore createManagedObjectContexts];
[RKManagedObjectStore setDefaultStore:self.managedObjectStore];
return self.managedObjectStore;
}

答案 0 :(得分：1)
您应该使用操作管理器来POST，而不是http客户端。通过这种方式，将映射要发布的提供对象以生成正文内容。
您将错过对象管理器的使用以及将使用的请求描述符的定义（如现有响应描述符），以找到适当的映射。请求描述符可以使用[meetingMapping inverseMapping]。
除此之外：如果你是，那么它不是100％清晰，但你不应该在每次做某事时重新创建整个核心数据堆栈。在您尝试发送任何内容/使用Core Data之前，只应调用setupCoreDataWithRESTKit一次，然后再调用。
在日志中：但是managedObjectStore是nil - ＆gt;所以你的核心数据堆栈配置不起作用，你需要进行调试才能弄清楚它是什么......
