I'm using LaunchImage.launchimage in Images.xcassets to manage the launch images. But I'm trying to use the launch images inside the app also.

I've read this answer :

The documentation indicates that the imageNamed: method on UIImage
should auto-magically select the correct version

So, I used this code

UIImageView *backImage = [UIImageView new];

backImage.image = [UIImage imageNamed:@"LaunchImage"];

When working on iPhone 4,5,6,6+ it works perfectly fine and get the correct LaunchImage, but when working on iPad retina it returns LaunchImage-700@2x.png which is the LaunchImage of iPhone 4s 640 x 960 pixels

So how can I access the correct LaunchImage of iPad programatically ??

I've solved this issue using a long method

BOOL deviceIsIpad = NO;

if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) {

    deviceIsIpad = YES;

}



if (!deviceIsIpad) {

    backImage.image = [UIImage imageNamed:@"LaunchImage"];

} else {

    UIInterfaceOrientation interfaceOrientation = self.interfaceOrientation;

    CGFloat screenScale = [[UIScreen mainScreen] scale];

    if (interfaceOrientation == UIDeviceOrientationPortrait || interfaceOrientation == UIDeviceOrientationPortraitUpsideDown){

        if (screenScale > 1) {

            backImage.image = [UIImage imageNamed:@"LaunchImage-700-Portrait@2x~ipad.png"];

        } else {

            backImage.image = [UIImage imageNamed:@"LaunchImage-700-Portrait~ipad.png"];

        }

    } else {

        if (screenScale > 1) {

            backImage.image = [UIImage imageNamed:@"LaunchImage-700-Landscape@2x~ipad.png"];

        } else {

            backImage.image = [UIImage imageNamed:@"LaunchImage-700-Landscape~ipad.png"];

        }

    }

}

I believe that those extensions (-700-Landscape@2x~ipad for example) are not recognisable.

Add the following item to your Contents.json just for testing purpose:

{

      "orientation" : "landscape",

      "idiom" : "ipad",

      "extent" : "full-screen",

      "filename" : "LaunchImage.png",

      "scale" : "1x"

}

Now try the imageNamed: method.

Or try the imageNamed: with the image full name:

backImage.image = [UIImage imageNamed:@"LaunchImage-700-Landscape~ipad.png"];

LaunchImage.launchimage

Are you really using Images.xcassets to manage the launch images?
Aren't you using LaunchImage.launchimage instead?

If so, there comes the confusion. You cannot load using [UIImage imageNamed:@"LaunchImage"]; from LaunchImage.launchimage.

Canonical names

• LaunchImage.png


• LaunchImage@2x.png


• LaunchImage-700@2x.png


• LaunchImage-568h@2x.png


• LaunchImage-700-568h@2x.png


• LaunchImage-700-Landscape@2x~ipad.png

LaunchImage-700-Portrait@2x~ipad.png is not in that list.
