ios - Changing device orientation settings by Device in Rubymotion -

i have universal app using rubymotion, , ui setup differs between iphone version , ipad version.

the main being, in iphone supports portrait, , ipad supports landscape.

i want this, if possible setting on rakefile, understand alternative in delagate method, if possible set orientation settings in settings file.

motion::project::app.setup |app|   #app settings   app.name = 'xxxxx'   app.version = "0.xxxx"   app.device_family = [:iphone, :ipad]   app.interface_orientations = [:portrait] end 

edit:

some updates on how jamon's answer worked out. having shouldautorotate return false in uinavigation resulted in odd occurrences on ipad version, having parts of ipad version show view content portrait though orientation set landscape, worked out when returned true shouldautorotate.

you won't able in rakefile, far know. need specify provide both orientations , programmatically tell ios whether orientation supported or not.

your uiviewcontrollers and/or uinavigationcontroller(s) should this:

def ipad?   nsbundle.mainbundle.infodictionary["uidevicefamily"].include?("2") end  def shouldautorotate   false # think? end  def supportedinterfaceorientations   if ipad?     uiinterfaceorientationmasklandscapeleft | uiinterfaceorientationmasklandscaperight   else     uiinterfaceorientationmaskportrait   end       end  def preferredinterfaceorientationforpresentation   ipad? ? uiinterfaceorientationmasklandscapeleft : uiinterfaceorientationmaskportrait end 

haven't tested code, i've used similar in past. can use ternary (like did in last method) or regular if.
