How to load specific image from assets with Swift [duplicate]

问题

I'm new to Swift and I want to load a special image from assets. For example I have:

image 1 for iphone 4s = green-square@2x.png
image 2 for iphone 5/5s = green-square-Retina@2x.png
image 3 for iphone 6s = green-square@3x.png

and I want to load for iphone 6 a specific image like

self.GSquare = SKSpriteNode(imageNamed: "./Images.xcassets/green-square-Retina@2x.png")

Is it possible?

回答1:

You shouldn't load images directly with @2x or @3x, system selects appropriate image automatically, you only need to specify the name, like UIImage(named: "green-square-Retina")

回答2:

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

回答3:

You can easily pick image from asset without UIImage(named: "green-square-Retina").

Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.

See this Stackoverflow answer for reference.
