在MFMailComposeViewController中访问收件人，正文等 [英] Accessing recipients, body etc in an MFMailComposeViewController

问题描述

我目前正在努力在启动过程中保持iPhone应用程序的UI状态，但是事实证明，在我的一个控制器(子类)中，这是一个问题.

I'm currently working on persisting the UI state of my iPhone app across launches, but it's proving to be a bit of an issue in one of my controllers - a sub-classed MFMailComposeViewController.

从本质上讲，我需要存储(在应用程序退出时)当前的To/CC/BCC列表，主题和正文，以便在重新启动后可以再次设置视图.不幸的是，Apple似乎只为这些数据提供了setter方法(例如setToRecipients:).

Essentially, I need to store (on app exit) the current To/CC/BCC lists, the subject, and the body so I can set the view up again after a relaunch. Unfortunately, Apple seems to have only provided setter methods for this data (e.g. setToRecipients:).

毫无疑问，那里有一些私人吸气剂，但我宁愿冒险被App Store批准者拒之门外...

No doubt there's some private getters in there somewhere, but I'd rather not risk getting bounced by the App Store approvers...

有什么想法/建议吗?

Any thoughts/suggestions?

推荐答案

最好的选择是使用controller.view，并在子视图层次结构中搜索所有UILabel.

The best bet is to use controller.view, and search for all UILabels in the subview hierarchy.

(此外，MFMailComposeViewController没有专用的获取器.这些设置器仅将消息委派给其内部实现类.)

(Also, there aren't private getters for MFMailComposeViewController. Those setters only delegates the message to its internal implementation class.)
