12547698: Crash while displaying mail compose view when tab bar text is customized

[openradar-mirror]

Description

Summary: If the mail compose view (MFMailComposeViewController) is displayed while the tab bar title text is customized using -[UIColor colorWithPattern:], an assertion failure occurs in -[UICGColor encodeWithCoder:]

Steps to Reproduce: Customize the tab bar using by setting a pattern colour for the title text appearance using -[UIColor colorWithPattern:]. The app will crash when you try to instantiate a MFMailComposeViewController. If you use an RGBA color instead of -[UIColor colorWithPattern:] the crash does not occur.

Expected Results: The mail compose view appears even when the tab bar title text is customized with a pattern colour.

Actual Results: Crash occurs with error message:
