Different Layout for Landscape

Good morning .. :)
To change the measures of the storyboard I usually do the following:
1st - I select the StoryBoard.
2nd - I go to the RIGHT side and select the icon Show the size inspector. 3rd - In the SIMULATED property SIZE I switch to FreeForm and then I change the dimensions of the
StoryBoard .. I let it look like LANDSCAPE ...

I hope I understand your doubts right ...
Anything is just talking

Good morning ..
Another way I realized now is the one I show in the image below:

In the part circled below (bottom left) to put the viewcontroller in landscape mode. And to illustrate the first response I gave, I circled the upper right corner to show where the property you had spoken to earlier is. Anything is just talking.

Good morning Danilo ...
Man I had not even noticed the iPad ...
In fact if you notice the first two images that I posted I normally do not work with AUTOLAYOUT enabled ...
When I enabled AutoLayout then I saw that the iPad option appeared. I tried to make a simple screen .. and using the constraints make her stay with a good aesthetic on several devices including iPad. I also tried to use the VARY FIR TRAITS as you mention ... Dude, it was a dumbbell only. So I deleted the view and started again from scratch. AutoLayaute enabled, Use Trait Variations enabled I put a VC with iphoneSE dimensions. I put the objects. I packed them the way I wanted them. I used on the SHOW THE SIZE INSPECTOR vane the AUTORESINZIG property of each object to "ANCORA-LOS" in the way you wanted it to.

Then you can set all the buttons in different formats.
Everything was cool ... both in Landscape and in Portrait. Below I put a print
ipone SE - portrait and landscape
ipone 5 - portrait and landscape
ipone 7 - portrait and landscape
Ipad pro 12.9 inch - portrait and landscape

Was that the difficulty ??? I understood the question right ??? :) If that's what you want, I can send you the StoryBoard. Home If you have questions just say it. Home Hugs.
