iphone - MFMessageComposeViewController 半透明键盘

Question

我正在尝试发起 MFMessageComposeViewController带半透明键盘。我想让它像我想要的那样透明，但我认为我们不能从我所做的阅读中做到这一点。

您将如何设置 UIKeyboard 的属性？当您创建 MFMessageComposeViewController ?

非常感谢!

你不。从文档中:

Important The message composition interface itself is not customizable and must not be modified by your application. In addition, after presenting the interface, your application is unable to make further changes to the SMS content. The user can edit the content using the interface, but programmatic changes are ignored. Thus, you must set the values of content fields, if desired, before presenting the interface.

您不应该更改此界面，因为 UIKeyboard 是私有(private)的，并且您无法访问此 View 上的文本字段。尝试通过 View 层次结构访问和修改此文本字段可能会导致您的应用在应用商店中被拒绝。
