Framework reference

Notes:

Mfmessagecomposeviewcont Roroller

• 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, mfmessagecomposeviewcontRollerdelegate-messagecomposeviewcontroRoller: didfinishwithresult: all methods can be notified and corresponding processing is performed here.

If running on ios3.0, the system prompts dyld: Symbol not found: _ objc_class _ $ _ mfmessagecomposeviewcont.Roller. 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/mfmessagecomposeviewcont in the. h fileRoller. H, changed to import<Messageui/messageui. h>
