![]() Xcode generates raster images that are based on the PDF image instead of scaling a vector at run-time. When you run the application, iOS will automatically pick the appropriate or image that Xcode generated based on the device requirements. For example, if you had a PDF that was 150px x 150px, then Xcode will generate the following PNG sizes for use in the application: ![]() When you build your project, Xcode will do the hard work, creating and PNG files from the vector PDF that you’ve used in the Xcode Asset Catalog. As you’ll see, the image is displayed perfectly on all screen types and sizes. Now you can run the app either on devices that feature screens with different resolutions (retina and non-retina), or do so using the Simulator. Just go to your ViewController and add the image as usual: The image set will change to just one drop point, labeled “All – Universal:”ĭrag and drop your vector PDF created above onto the drop point:ĭone. Under the Scale Factor drop-down menu, select “Single Vector:” In the new image set that appears, select the blank image set, then show the Utilities panel: ![]() Select “New Image Set” from the Editor menu: Here’s how you can add the vector image in Xcode:Ĭreate an XCAsset file, or open one if you already have it in your project: You can mix standard image imports and XCAssets without any issues. In order to create vector images in Xcode, you’ll need an Xcode Asset Catalog to manage your images. Once the design is complete, the exported PDF will be a scalable vector, perfectly capable of scaling to the and resolutions in iOS. The app design team at ArcTouch typically uses Sketch. To begin, you’ll need a vector PDF exported from your favorite vector-based drawing tool at the size. You may be asking, so how do I create vector images in Xcode? The process involves two major steps. Xcode does the heavy lifting so the image displays in the proper sizes on the different devices and in your app’s different screens. When you create vector images, instead of using three copies of the same image in three different sizes, only one file is required. Vector images, a feature first introduced in Xcode 6, allows single assets to scale to all sizes. For iOS, using Xcode to create vector images helps mobile app designers and developers simplify that task.įor many apps, you need icons and splash screen images in different sizes, and also and versions for each asset inside the app. But with all of the different device and screen sizes, creating and managing that artwork for all the permutations has always been a challenge. Strong imagery gives apps more character and makes them more engaging. Here's the best part, simply copy the files (including the Contents.json!) into you AppIcon directory within your Xcode project.Creating artwork for your mobile application is a crucial part of the development process. Navigate to the directory that contains the AI-to-iOS-Icon-Generator.jsx script and open it to run.Īn alert will tell you where the generated files have been created. Open your MagicCasts.svg in Adobe Illustrator. See the thread discussing this problem: ExportOptionsPNG24 with large scale Generate the Icons Because of rounding issues within Adobe Illustrator, some icons may render a pixel off, which will fail within Xcode. ![]() Preparationĭownload the two scripts and our MagicCasts SVG icon:Įnsure that your icon is 100 x 100. Simply open the icon, run the script, and drag the generated files into your Xcode project. We've built an Adobe Illustrator Creative Cloud JavaScript program to take a vector-based icon and output applications icons for your iOS project. If you add OSX, tvOS, watchOS, or any older OS versions, you may need to generate up to 40 app icons! If you decide to modify your icon, you'll have to start this process all over again. If you just support iOS 7.0 and later, you must generate at least 13 icons. Generating application icons for Apple devices can be a hastle.
