根据文件记载:

< a href=>http:// developmenter.apple.com/library/ios/#documentation/MessageUI/Reference/MFMAILOUTOS View_class/Reference/Reference/Reference.html>http://developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMAILCompososeViversion_central_clas/Reference/Reference.html

Important The mail composition interface itself is not customizable and must not be modified by your application. In addition, after presenting the interface, your application is not allowed to make further changes to the email content. The user may still edit the content using the interface, but programmatic changes are ignored. Thus, you must set the values of content fields before presenting the interface.
