ios_21 Buy _ipad Neutron controller screen adaptation

Eventually:

Important screen fitting tips for your ipad ,

First add a contentview placeholder ,

And only set the frame in the viewdidload method ,

Because in the IPad , whether it's a horizontal or vertical screen , W is a narrow edge ,

So , first add a contentview to the right side of the host controller ,

And let it automatically scale with the main controller's width and height ,

The view of the sub-controller can only be added to contentview , x 0 y 0 wide is Contentview bounds
