• Mfmessagecomposeviewcontroller

Ios4.0 is added with mfmessagecomposeviewcontroller and mfmessagecomposeviewcontrollerdelegate. It provides an interface for sending text messages and does not need to jump out like sending an email.ProgramFor more information, see message UI.
Framework reference

Notes:

Mfmessagecomposeviewcontroller

• Provides an operation interface
• You must check the cansendtext method before using it. If no is returned, the Controller should not be displayed, but the system should prompt that the user does not support sending text messages.
• The interface cannot be customized by yourself.
• The content (body) and the recipient (recipients) of the text message to be sent must be initialized before the controller is displayed. After the display, the text message content cannot be modified through a program. however, you can manually modify the text message content and select recipients.
• When the user clicks send or cancel, or fails to send, the-messagecomposeviewcontrollerdelegate-messagecomposeviewcontroller: didfinishwithresult: method can be notified, and corresponding processing is performed here

If running on ios3.0, the system prompts dyld: Symbol not found: _ objc_class _ $ _ mfmessagecomposeviewcontroller. solution:

1. Select weak for the introduced type of messageui. Framework (modify it in target-> get info-> General-> linked libraries-> messageui. Framework-> type)
2. Do not directly import messageui/mfmessagecomposeviewcontroller. h In the. h file, and change it to import <messageui/messageui. h>
