Instance Method


A Boolean value that indicates whether the current content and attachments are valid.


- (BOOL)isContentValid;

Return Value

YES if the current content and attachments are valid for posting, otherwise NO. The default return value is YES.


This method is automatically called after each change a user makes to the text in the compose view. You can use this method to determine whether the Post button should be enabled and to update charactersRemaining, if necessary.

A subclass should implement this method to perform custom validation of the user’s content before initiating a post.
