IOS setting - image sizing required for selected iOS deployment target
Understanding the image sizingĪs you can see in the central area of the file contents, there are placeholders for images with various labels that consist of combination of the following components:Ĭomponent - Notification, Spotlight, etc. Should you need a direct access to each image, you can explore its structure in detail by clicking 'Show in Finder' in the context menu: Image assets groupĪssets.xcassets is called the Asset catalogue. In fact, the image assets are represented by a number of files grouped together as a folder. It also must have specific requirements for all the images, which is why Xcode provides placeholders for those images. Remember, the app icon images are mandatory for the App Store submission. The only elements it contains by default are grouped placeholders for the app icon. Let's select AppIcon from the contents panel: Xcode images assets default contents
Let's switch to the assets file included in our project. This is also where the app icon images must be supplied. Each project may have multiple image assets files. They are stored in a special file format with an extension. Other assets are optional (they depend on the app context), such as custom fonts or other images. Some are required (we cannot submit an app to the App Store without them) such as an app icon. Now, a good way to start implementation is to incorporate the assets.Īssets, in terms of an Xcode project, are external elements that need to be incorporated in the project. We have our designs and requirements handy.
