12/20/2023 0 Comments Xcode icon pixel size![]() ![]() IPhone apps require only one launch image in a portrait orientation, whereas iPad apps typically require different images for portrait and landscape orientations. Typically you have to include one launch image in a portrait orientation for iPhone apps, as well as, iPad apps. Universal apps must provide launch images for both the iPhone and iPad. To keep it simple, we’ll briefly discuss three types of resources including launch image, app icon and app images. For instance, if you use images, you may need to add larger (or higher-resolution) versions to support iPad devices. Other than two versions of storyboard or interface builder, you’ll have to create two versions of resource files. You will end up with a storyboard similar to the below. Under Attributes Inspector, change the button type to “custom” and set the button image as button_play.png. Next, add a button object to the controller. MainStoryboard_iPhone.storyboard) and design the UI.įirst drag an image view into the view controller and set the image as background-menu.png. Assuming you’ve created a Xcode project for universal devices (or you can download the project template to jump start), let’s first go to the iPhone version of storyboard (i.e. ![]() We’ll develop a very simple app to illustrate how you can create a universal app using Storyboard. Say, when you open the app on iPhone, the iPhone version of storyboard is used and you’ll see the views of iPhone version. You define different version of views or view controllers in each storyboard. This is how you can design custom interface for different devices in a single Xcode project. Obviously, the view controller for iPhone (and iPod touch) differs from that of iPad.Īs you can see, each device has its own version of Storyboard. This still involves a lot of extra work to optimize the view controllers due to the differences in device screen sizes. That said, the whole process is not automatic. Xcode makes coding universal apps simple. With universal app, you create a single binary that caters for multiple iOS devices with different screen sizes. And if user runs it on iPad, he/she will be see the iPad version, not the “blown-up” version of iPhone app, but the custom designed version for the iPad.īefore Apple introduced the concept of universal app, developers would have to create two binaries – one for iPhone and the other for iPad. When user opens the universal app on iPhone, one will see the iPhone version. From user’s perspective, this provides the best user experience without downloading two different versions of apps. I've tried to add all of the required icons to some native XCode projects Assets.xcassets tab and it works fine.IOS iOS Programming Tutorial: Creating a Universal AppĪ universal app is a single app that is optimized for iPhone, iPod touch, and iPad devices. My ist file looks like this: file was generated by Qt/QMake. In "Platform Notes - iOS" article there's a mention "The filename is not important, but the actual pixel size is.", I've tried all kinds of icon sizes, I've added all of them to QMAKE_BUNDLE_DATA, but the tabbed out app icon still isn't present. I'm testing this on an iPhone 5SE with iOS software 14.8.1 I can see the icon when my app is on my home screen, however, the issue persist, that I can't see an icon when the app is tabbed out (as shown in screenshot before). ![]() The solution seems kind of a hassle, but hey, it works! ![]()
