出现这个这个错误, 有可能是由于你直接通过一个数组的索引获取一个对象(或模型)然后直接调用这个对象(或模型)的某个方法
例如:
NSString *status = [self.models[indexPath.row] status];
应该改为:
RPModel *model = self.models[indexPath.row];
NSString *status = model.status;
这样就能消除这个错误啦...

The cast to value type 'System.Decimal' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.
A query was run and no Result Maps were found for the Mapped Statement 'user.insertUser!selectKey'. It's likely that neither a Result Type nor a Result Map was specified.
