Use images on Asset Catalog in Interface Builder

问题:

Is it possible to use the images added to Assets Catalog directly on interface builder? How is that done?

On UIImageView properties I can't see any option to reference any image on assets catalog.

回答1:

1. Import the images into the .xcassets folder
   
   • click the '+' in the bottom right, 'Import folder'
2. Setup each image with its 1x and 2x image size
3. Give it a name

Images can then be referenced programmatically with UIImage *image = [UIImage imageNamed:@"some-image"], or via the image dropdown in IB/Storyboards.

回答2:

All of the images in an asset catalog have a name. This name can be used in imageNamed: and in IB.
