在Playground上添加iOS资源

Question

According to documentation :

IOS resources should be added inside the App_Resources\\ios folder in your app. You can use @1x, @2x and @3x suffixes to target devices with a specific screen scale. Here is a list of devices for each scale factor:

@1x - iPad 2 and iPad mini (1st Generation) @2x - iPhone 4s, iPhone 5, iPhone 6, iPad (retina) @3x - iPhone 6 Plus

However, if I try to name a file photo@1.png in Playground I receive an error:

The specified file name is invalid. Only alphanumeric characters (including "_", "-" and ".") are allowed.

How can I solve this?

Answer 1

When working with Xcode Playgrounds, you can use the following workflow to rename images to your desired format:

1. Press ⌘1 to open the Project Navigator

2. Drag your image into the Resources folder (it appears, but is blurred out as long as you don't have any files in it

3. Rename it to have @1x.png etc. at the end
