Step 1: Select the asset catalogĪs in the screenshot above, click Assets in the project navigator to bring up the Asset Catalog for the project. To add an image to the project, create a new image set. Drag the png or jpeg asset or assets from the Finder to the 1X or 2X slot. In a production app, you should include both the standard (1X) as well as retina (2X) asset. During development, you can add only one asset and Xcode will automatically create the other one, although it may look blurry. Any image set in the Asset Catalog will be listed in the image drop down menus.Įxample 2: Using the image set programmatically Step 3: Using the image set Example 1: Using the image set in Interface BuilderĪny control that has images like UIImageViews or UIButtons can set images in Interface Builder. var chat = UIImage ( named : "Chat" ) var chatImageView = UIImageView ( image : chat ) UIImage * chat = UIImageView * chatImageView = initWithImage : chat ] Image Literals To access images in the Asset Catalog programmatically, create UIImages using the imageNamed: method as shown in the snippet below. In Swift, Image Literal offer another way to add images. NOTE: The technique above, initializing a UIImage using its name, still works too.įor the launch image, you will need to configure the LaunchScreen Storyboard file as you would any other ViewController. Add your Launch Screen Asset to the Assets folder.Developing, building, running, and debugging a Qt for iOS application can all be done with Qt Creator on macOS.The toolchain is provided by Apple's Xcode, and running qmake on a project targeted for iOS will also generate an Xcode project file (.xcodeproj), with initial application settings. As Qt Creator does not provide an interface for managing all of the settings specific to iOS platform, it is sometimes necessary to adjust them in Xcode directly. Checking that the application is configured correctly is especially important before submitting an application for publishing in Apple's App Store. Information property list file (ist) on iOS and macOS is used for configuring an application bundle. Application display name and identifier. See the documentation on Information Property List File in iOS Developer Library for details. When qmake is run, an ist file is generated with appropriate default values. It is advisable to replace the generated ist with your own copy, to prevent it from being overwritten the next time qmake is run. QMAKE_ASSET_CATALOGS += ios/Assets.xcassets You can define a custom information property list with QMAKE_INFO_PLIST variable in your. Icons need to be set in the ist and copied to the application bundle. Xcode has special support for icons, but when using Qt, it is usually better to set them in the. To support all resolutions and devices, several images should be created. The filename is not important, but the actual pixel size is.Ī detailed list of what is required is available at Icon files.
