It is not available via MDCTypography?

[gambard, 2017/01/18 12:37:57]

Done.
It is but showcase does not load the roboto font in MDCTypography.
  [MDCTypography setFontLoader:[MDFRobotoFontLoader sharedInstance]]; should
probably be added to showcase app delegate.

Since you set the leading and trailing for the title below, you don't need this,
do you?

[gambard, 2017/01/18 12:37:57]

Done.
