问题
I am trying to change font size of uilabel for iphone 4 and iphone 5 using autolayout and size classes. IB is giving option only for ipad and greater phones like iphone 6 and 6P .
If i change font for wR and hR then it changes fonts size for iphone 4 , 5 and 6 which is wrong in my case .
Please help me in this regard.

Unfortunately , Apple Provides minimum consideration for all iPhone's(4,5,6,6p version) Portrait Mode Compact Width - Compact Height or Compact Width - Regular Height. So You can't specify Font Size separately for different iPhones in Portrait Mode from Storyboard.
