Question

我准备通过继承UIAlerView来提交这样的自定义。它的布局完全基于UIAlertView的给定地形，没有读取任何私有财产。 App Store审核流程是否接受这种自定义？

Answer 1

问题的实际答案是否 - Apple不允许 UIAlertView 进行子类化。来自UIAlertView文档：

子类注释

UIAlertView类旨在按原样使用，但不是   支持子类化。此类的视图层次结构是私有的   不得修改。

在这里找到： Subclassing UIAlertView

Answer 2

除了Apple之外，没有人可以充分回答这个问题，所以最好的办法是对它进行测试。我认为你要问自己的主要问题是：我是否违反了Apple开发者协议中的任何条款？如果没有，请提交您的应用。如果您担心拒绝，请考虑另一种可以做到这一点的方式，作为备份，并准备好在出现问题时提交。

并非你曾经问过，但我也认为这种对Apple设计的改变不是很直观。你的意思是转换为“也从moquus删除？”因为你已经有一个很大的删除按钮。如果开关关闭，那么删除按钮会删除什么？

是否允许Apple定制UIAlertView？
