Ios 核心数据验证中的崩溃

在核心数据上下文保存期间，如果我的模型中有以下代码，我会遇到崩溃（分段错误）：

class Tag < CDQManagedObject
  def validateName(valuePointer, error: errorPtr)
    puts valuePointer[0]
    true
  end
end

很抱歉回答我自己的问题

这是RubyMotion中的一个缺陷，已在2.25中修复：

• 修复了Ruby中定义的KVC属性验证方法无法验证的错误 必须使用适当的（指针）类型进行编译

---

能否显示导致调用validateName的代码？
