Answer 2

First you have to declare App Launcher icon images

Device      size                   retina display size
iphone     57*57  (icon.png)         114*114 (icon@2x)
iPad        72*72                    144*144

Launch Image size
Device      size        retina display size
iphone     320*480           640*960
iphone 5    640*1136 
iPad        768*1024         1536*2048

And to specifies your icons go to the Target then summary then you browse icon (manually) for all the device name doesn't matter but name not be same.

Answer 3

Please refer the default icon names..

 Iphone(non retina) :icon.png 

Iphone(retina) :icon@2x.png

Ipad(Non retina) :Icon-72.png

IPad(Retina) :Icon-72@2x.png

Answer 4

Add a CFBundleIconFiles key of type Array to your Info.plist. The array should contain 2 string items: the filenames of the two icons. The OS will then automatically choose the correct icon for each platform based on their pixel dimensions.

Answer 5

I think you can create app icon set in images.xcassets and that will save a lot of time
