iOS-SQLCipher子查询谓词在EncryptedStore中不工作

iOS-SQLCipher子查询谓词在EncryptedStore中不工作,ios,objective-c,core-data,nspredicate,sqlcipher,Ios,Objective C,Core Data,Nspredicate,Sqlcipher,我有一个现有的coredataios项目,它有很多子查询谓词。我想加密我的sqlLite文件。在通过EncryptedStore实现sqlchipher时,对于下面方法中的子查询谓词,我面临“不支持的表达式类型4” - (void)parseExpression:(NSExpression *)expression inPredicate:(NSComparisonPredicate *)predicate inFetchRequest:(NSFetchRequest

- (void)parseExpression:(NSExpression *)expression
        inPredicate:(NSComparisonPredicate *)predicate

           operator:(NSDictionary *)operator
            operand:(id *)operand
           bindings:(id *)bindings {....}

请建议如何解决此问题或任何替代解决方案
