我是靠谱客的博主忧郁摩托，这篇文章主要介绍ios中经过调试来使用私有ipa，现在分享给大家，希望可以做个参考。

ios中通过调试来使用私有ipa

iOS不允许使用ios私有ipa，使用私有ipa可以获得意想不到的效果，同时使用私有ipa是一个程序员的技术体现之一。至于怎么通过apple的审核，其实是有些办法的，但是不属于今天讨论的范围。私有ipa可以通过dump头文件获得，也可以去github clone一份现成的，但是还是推荐自己去dump。但是我们今天不是讨论，如何使用dump到的ipa，而是通过一个例子来讨论如何通过查看头文件使用私有api。

我们以UITextfield为例，其实这是个比较简单的控件，有一个蓝色输入的光标，可以在你输入的时候隐藏或者显示，但是并没有给我们提供改变光标颜色的接口，这个时候我们如果要改变光标的颜色，必然要使用私有ipa（或者通过比较啰嗦的办法来做这这件事情）。
我们首先需要dump一包头文件，如何class-dump，不是我们今天讨论的要点，现在我们贴上UITextfield的头文件。如果你觉得很长，直接拖到最后面。

首先我们看它声明的方法，关于cursor 的函数，或者表示类似颜色设置的函数，一看之下，没有。这个时候我们注意到有一个函数是 - (id)textInputTraits;

字面意思上是文本输入特征的意思，这个很有可能是我们需要的设置光标的颜色，ok，现在我们开始写代码。

省略创建project的步骤，直接上代码

我们看到private 下面，有一行是标识color的，很可能这个就是我们找的光标样色的属性。同样我们看一下 UITextfieldTraits的头文件，找到我们需要调用的函数。
