I have two textfields and labels in a row and I want them to stretch in proportion when orientation changes to landscape.
Here are the constraints
With current constraints I am getting following output
Notice how only the label was stretched.
I am not sure what additional changes are needed to the layout.
Right click on label that you've selected in above shown image and drag the mouse pointer to the its superview you got op up smthg like below and select equal width.
When you done above step your component is streched to whole view so dont panic now select your component again and open size inspector. click on width constraint you got below screen
Now change the multiplier like this
Do same for all components and give multiplier as what width you wanted to set. It automatically works for you in all screens iPad and iPhone and all orientations.
