Access iPad launch images programmatically?

Question

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 ??

The contents of Contents.json in LaunchImage folder

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"];

if this didn't your too. you need to get the Images.xcassets bundle. please confirm. I will add the code that gets Images.xcassets bundle. – hasan Aug 09 '15 at 08:57
Sorry.. event after renaming `LaunchImage-700-Portrait~ipad.png` to `LaunchImage.png` and editing the `Contents.json`, nothing changed and still returning iPhone 4s image – MujtabaFR Aug 09 '15 at 13:16
But when using full image name like this `[UIImage imageNamed:@"LaunchImage-700-Landscape~ipad.png"]` it works.. but that will need much more codes to work well – MujtabaFR Aug 09 '15 at 13:18
I know. Thats never worked for me too. I believe that apple never rly supported this 100% for all these extensions. Only some works. The simple ones as @2x only – hasan Aug 09 '15 at 13:21

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.

Yes, I'm using `LaunchImage.launchimage` which is inside `Images.xcassets` – MujtabaFR Aug 09 '15 at 13:20

Even after renaming `LaunchImage-700-Portrait~ipad.png` to `LaunchImage-700~ipad.png` and editing the Contents.json, nothing changed and still returning iPhone 4s launch image – MujtabaFR Aug 09 '15 at 13:21
