How to set the font size and buttons the same for iphone4s, 5 and different for iPhone6 ​​and 6+ devices?

Question

I’m working on an iOS application, and I watched the interface in iPhone 5,6,6+, all fonts are different devices on the device, but my requirement is that the button sizes and font sizes should be the same for iPhone4s, 5 and different for iPhone 6 and 6+. How can I do this in my application. I know that we can do this programmatically, but is there a chance to do this on a storyboard using responsive layouts.

I am using xcode7.2, swift2.

Thanks in advance.
