iOS launch images file type

Question

I'm working on an iPad app and reading this page that said launch images must be in PNG format, but in their iOS Human Guidelines, they only recommend to use .png, not "a must". I want to use .jpg format as my launch images because my launch images size in .png are about 2 mb alone, and only 90 kb in .jpg format. Thanks

You need to specify in the Info.plist the UILaunhImageFile field

    <key>UILaunchImageFile</key>
    <string>Default.jpg</string>

Setting this information will make the system look for Default.jpg and all its variations (portait, landscape, @2x, etc) instead of .png

for example, I'm coding an Universal app, and now all the launch images are .jpg, including iPad Retina: [email protected]
