ios - Background image for LaunchScreen.storyboard -


i using storyboard launch screen.

it has full size uiimageview artwork , language dependent uilabel rendered on it.

i have .png files possible iphone screen sizes (ipad not necessary).

the artwork contains circle looks distorted when use same image iphone 4s , iphone 5.

approach 1

in launchscreen.storyboard, add uiimageview iphones , use imageset, defined in assets.xcassets.

when this, image@2x of image set used iphone 4s , iphone 5 5s. 1 of both looks bad, because iphone 4s , 5 have different heights.

i not aware can use size classes in storyboard distinguish between iphone 4s , iphone 5. or can i?

approach 2

create launch image set in assets.xcassets, can hold necessary image sizes.

i can't select launch image set in uiimageview image.

question

in full size uiimageview in launchscreen.storyboard: how display different pngs for

  • iphone 4 + 4s 640 x 960 pixels
  • iphone 5 + 5s 640 x 1136 pixels
  • iphone 6 + 6s 750 x 1334 pixels
  • iphone 6 plus + 6s plus 1242 x 2208 pixels (portrait , landscape)

the main problem appears distinguish between 4 + 4s , 5 + 5s.

a circle looks distorted when use same image iphone 4s , iphone 5.

the problem content mode of image view. use content mode not stretch image out of aspect ratio.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
