Impossible to load an image in xcassets on bundle

Question

I need to include images in a static library. I created a bundle and inserted in my images, the problem is that it seems to work if I include the images directly in the bundle, but stops working if I put in a xcassets file.

I followed many guides and searched for a solution on this site. The most popular solution is to insert this line of code:

[UIImage imageNamed:@"MyBundle.bundle/imageName"] 

but it seems not work for me

any ideas?

Answer 1

For Swift 2.1:

let bundle = pathToBundle // define for your app or framework
if let image = UIImage(named: "drop_arrow", inBundle: bundle, compatibleWithTraitCollection: nil) {
    // process image
}

Answer 2

There are two ways to solve this,

If your app is still supporting iOs 7, you can use this category: https://gist.github.com/serluca/e4f6a47ffbc19fccc63e

Otherwise, starting from iOs 8 Apple added a way to do this using: + imageNamed:inBundle:compatibleWithTraitCollection: defined here

Answer 3

Running the same problem. Looks like inline bundle support is broken for XCAssets in the 1-parameter imageNamed method. There's a workaround though using imageNamed:inBundle:compatibleWithTraitCollection: Be careful, this is iOS8 only !!

NSBundle *bundle = [NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:@"static_lib_bundle_name" ofType:@"bundle"]];
UIImage *image  = [UIImage imageNamed:@"image_in_the_xcassets_you_want" inBundle:bundle compatibleWithTraitCollection:nil];

NOTE : traitCollection is set to nil to pass the main screen traits as per apple docs (i don't quite get what it means though, if anyone knows please comment!).
