This is a good thing to keep in mind if we don't see our custom font inside the app and we're sure we did every step of the setup correctly.Pickers allow users to choose a single option from a collapsible list of options when space is limited. For these cases, we'll need to include the correct variant for the font and use that as font-family (for instance, Open Sans Bold). In some cases, if the styles of the text component have an extra property that modifies the font (like font-weight: bold), the font will not appear and the device's default font will appear instead.The code in the example uses the latter method. If that's the case, it's recommended to either change the name of the file so it's the same for both, or to use the Platform module to check if it's Android or iOS and use the correct one. ![]() As mentioned above, for Android sometimes matching the name of the file is enough to use the custom font and this could be different from the name that we'll need to use for iOS.For up-to-date documentation, see the latest version ( 0.70 ). Your App.tsx file import 'react-day-picker/dist/style.css' This will add the DayPicker stylesheet into your app. Multi Picker - Pick a single icon or multiple icons. This is documentation for React Native 0.60, which is no longer actively maintained. DayPicker comes with for a minimal, lightweight appearance: import react-day-picker/dist/style.css into your root component, or bundle it within your build pipeline. Pagination - Show a sane amount of icons per page. Categorization - Filter icons by category. It has built in support for: Fuzzy Search - Search icons by title. iOS: TTF, OTF, WOFF (iOS 10+), WOFF2 (iOS 10+).Ī few things that could happen to keep in mind and avoid countless hours of debugging (like it happened to me when first playing around with custom fonts □) React FontIconPicker is a React Component for displaying an interface to pick fonts or SVG out of a collection.So far, these are the supported formats for Android and iOS: If we add the correct name, then we should see the new font showing in the app: For Android:įortunately, for Android, most of the times by using the name of the file (minus the extension) will do the trick. Then run the app and check the output log inside Xcode, which should list the available fonts with the correct names. NSArray *fontFamilies = for (int i = 0 i < i ++ ) The other option, if you have Xcode available, is to add this code in your application code: Though most of the times the correct is the last one, there are cases where it could be any, so we'll need to do a bit of trial an error until getting it right. If you are using macOS/OS X, the simplest way to get the name of the font is by using Font Book, a utility app that's included by default:Īfter opening Font Book, we'll just need to look for the font we want and in the description look for any of these 3 values: PostScript name, Full name and Family. To get the correct name of the font, there is a couple of different methods: Using Font Book (macOS/ OS X) On top of that, sometimes this name is different between Android and iOS. ![]() “assets” is an array that can have multiple paths that react-native will search to link the filesįor the app to show the font, we have to include the correct name of the font, which a lot of times may not be the same as the file name or the one that appeared in the font description or shows in certain apps that use custom fonts (such as word processors or image editors). By using react-native link (which is included in React Native - you can find more info about how it works in this link) we can create the necessary links for the fonts to work with the native code, in both Android and iOS.įor react-native link to look for the font assets and link them to the native projects, it's necessary to add an extra section to the project's package.json specifying the path where the fonts are stored: The following example uses an onSelectionChange handler to update the selection stored in React state. Picker will pass the selected key to the onSelectionChange handler. You can handle all of these via the onSelectionChange prop. Thankfully, this step, which back in the day used to be the biggest pain in the process, is now quite straightforward. Picker supports selection via mouse, keyboard, and touch. Path is optional, can be any as long as it's inside the project Step 3: Linking the fonts to Android and iOS In either case, after getting the fonts, these need to be included in any path inside the project (image is a suggestion, but feel free to choose whatever fits your project best): If you already have your fonts on your computer, then you're all set! But in case you haven't, you can use Google Fonts to look them up: React-native init JohnCenaInspirationalQuotes Step 2: Getting those sweet fonts
