我的restKit /核心数据存在问题。我在没有使用核心数据的情况下使用了app。一切都很好。但是当我在核心数据轨道上翻译所有内容时，我的应用程序开始下降有些搜索让我想到relationshipMappingFromKeyPath中的问题，因为如果没有这一切，一切都会完美无缺。
我的代码：
NSString *URLPath = [NSString stringWithFormat:@"/v1/projects/%ld/tasks", projectId];
NSDictionary *mappingDictionary = @{
@"id" : @"taskId",
@"attrs.state" : @"state",
@"attrs.priority" : @"priority",
@"attrs.title" : @"title",
@"attrs.createdAt" : @"createdAt",
@"attrs.finishedAt" : @"finishedAt",
@"attrs.problem" : @"problem",
@"attrs.solution" : @"solution",
@"attrs.spent" : @"spent",
@"attrs.complete" : @"complete"
};
NSDictionary *taskSolutionDictionary = @{
@"fileName" : @"fileName",
@"URL" : @"urlString",
};
RKEntityMapping *taskMapping = [RKEntityMapping mappingForEntityForName:@"SMTask"
inManagedObjectStore:[[RKObjectManager sharedManager] managedObjectStore]];
[taskMapping addAttributeMappingsFromDictionary:mappingDictionary];
RKEntityMapping *taskSolutionMapping = [RKEntityMapping mappingForEntityForName:@"SMTaskSolutionFile"
inManagedObjectStore:[[RKObjectManager sharedManager] managedObjectStore]];
[taskSolutionMapping addAttributeMappingsFromDictionary:taskSolutionDictionary];
[taskMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"related.subtasks"
toKeyPath:@"subTasks"
withMapping:taskMapping]];
[taskMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"attrs.solutionFiles"
toKeyPath:@"solutionFiles"
withMapping:taskSolutionMapping]];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:taskMapping
method:RKRequestMethodAny
pathPattern:URLPath
keyPath:@"data"
statusCodes:statusCodes];
[[RKObjectManager sharedManager] addResponseDescriptor:responseDescriptor];
NSMutableDictionary *resultParams = [NSMutableDictionary dictionaryWithObject:@(page) forKey:@"page"];
[resultParams addEntriesFromDictionary:params];
但每次我都有这个错误：
