领域错误:属性需要定义所包含类型的协议 [英] Realm Error: Property requires a protocol defining the contained type

问题描述

我有以下模型，正在使用Realm:

I have the following model and I'm using Realm:

@interface GUIRoutineModel : GUIModel # GUIModel is a subclass of RLMObject

@property (nonatomic, retain) NSString *dateCreated;
@property (nonatomic, retain) NSString *dateModified;
@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *type;

@property NSInteger userId;
@property int routineId; #also have same issue using NSInteger


@end

当我打电话时:

   // Persist to Realm DB
    RLMRealm *realm = [RLMRealm defaultRealm];
    [realm transactionWithBlock:^{
        [realm addObject:routineModel];
    }];

我收到以下错误:

'Property 'routineId' requires a protocol defining the contained type - example: NSNumber<RLMInt>.'

我尝试将routineId属性更改为NSNumber<RLMint>，但这也不起作用.谁能告诉我我在做什么错?

I have tried changing the routineId property to NSNumber<RLMint>, but that didn't work either. Can anyone tell me what I'm doing wrong?

更新:

这是我尝试过的模型的另一个版本:

Here is another version of the model that I have tried:

@interface GUIRoutineModel : GUIModel

@property (nonatomic, retain) NSString *dateCreated;
@property (nonatomic, retain) NSString *dateModified;
@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *type;

@property NSInteger userId;
@property NSNumber<RLMInt> *routineId;

@end

推荐答案

Property requires a protocol defining the contained type error仅由Realm针对类型为NSNumber的属性生成，而没有协议注释预期的具体类型.这意味着不能为您提到的任何一个模型类生成它.您的应用程序其他位置可能还有另一个routineId属性，该属性会触发错误.

The Property requires a protocol defining the contained type error is only generated by Realm for a property of type NSNumber without a protocol annotating the expected concrete type. That means it cannot be generated for either of the model classes you mention. It's likely you have a another routineId property elsewhere in your app that is triggering the error.
