I need a custom generic select picker for ios and android to react-native. How I'll develop a custom picker to use my all components.
You can create 2 files Select.android.js and Select.ios.js in your components folder (or something else) for each OS, and import your Select component by
import Select from 'components/Select'

I'm creating a vue native app but the input text looks like an input text on HTML. I thought vue-native would create a native input with native styles per device.
Do I forget something?
I found https://nativebase.io/ which seems to be the solution I need. Since I'm new on this native apps, is this library the way to implement native styles per device?
While react-native renders native views, it doesn't take native (platform and os-version-specific) styles to apply to them. These would look different on each platform and version of the device, and also be impossible to style from react-native. There are some components that look like native ones (e.g. Button, Switch) but they are also styled from react-native so that you can override any styles you want
So yes, the only way to make react-native views look like native ones is to style them accordingly, and that's what libraries like nativebase do
I'm starting with React Native and I'm wondering if is possible to apply the default OS style for each element so I have not the need to handle every element style so imagine I have a form and simple text list, for the iOS app it should have iOS form and text style and for the Android app its default style.
As far as I've seen there is no official documentation for this commitment but I would like to ask here if there is a workaround for this.
As far as I am aware the default components within React Native does normally default to the OS style, for instance the Button component will render differently according to each platform.
As all the components that come with React Native are bare-bones, you'll have to define the styles yourself according to each platform which can be done with the Platform module: https://facebook.github.io/react-native/docs/platform-specific-code
If you don't want to style each component yourself then you can use a library like: react-native-elements (https://react-native-training.github.io/react-native-elements/) which handles a lot of what you desire.
I'm trying to understand how I can do a signature capture in React Native. My App is created with create-react-native-app and Expo and I'd prefer to not have to eject the app to get this functionality to work.
Would it be possible to wrap something like this in a webview? https://github.com/szimek/signature_pad
I've also looked at this project, https://github.com/RepairShopr/react-native-signature-capture but it requires me to eject the app and use react-native link.
Looking for any advice or suggestions on how to implement this feature while keeping my project as straightforward as possible (ideally, using create-react-native-app, but if this isn't possible could someone please explain to me why?)
The way React Native works is that each component available in React Native maps to a native component in the underlying platform.
ie. a <Image /> is an ImageView in Android and a UIImageView.h in iOS.
The Javascript code itself runs in a Javascript thread on each platform and as you use Components in React Native, there's a translation layer that passes information from JS into the React Native bridge that then results in corresponding native components being created.
By default, React Native has included the following components: https://facebook.github.io/react-native/docs/components-and-apis.html#basic-components which means that only those components come out-of-the-box in React Native. If you want other components, then you have 2 options, either create a "composite" component in which your JS component is written into other JS components or, if your feature needs a native component not yet exposed by React Native, write your own "native" component to expose certain native functionality to your React Native code.
The way Expo works is that they have wrapped React Native and a handful of 3rd party components and built it within their application. The reason why you can't use a 3rd party native component they don't support is because when that component is used, the app itself doesn't have translation code to go from JS to a native Android/iOS view.
So, to do what you're asking, you'd need to find either a "native" drawing component that Expo has included in their platform/app. OR you need to find a "composite" drawing component that is built with other default React Native components (or other components Expo supports).
ie. On Android, I might build this with a Canvas view, but from what I can tell React Native doesn't support that object natively, so I would probably write this myself, etc.
It's hard for Expo to support every 3rd party "native" component out there because React Native is open source and it iterates so fast that most community-built components aren't always up to date or they might conflict with one another.
I am using react-native-signature-capture.
Working properly on both Android and iOS.
I know it's been a while, but there is an interesting article here: https://blog.expo.io/drawing-signatures-with-expo-25d1629ca1ac
Wait, but how?
Using “expo-pixi”, you can add a component that lets you choose your brush’s color, thickness, and opacity. Then when your user lifts her finger, you get a callback. From there you can take a screenshot of the transparent view or get the raw point data if that’s what you’re looking for.
I am bridging React native and Swift Modules. I have completely done that. I am trying to add my existing IOS project and wanted to add in React Native.
For instance, When i create a new project for ReactNative. My Current Project become
ReactNative/ios
Now Is there any way to export the IOS project directly in the folder and make a reference to call from React Native ?
You can bridge native with react native. you can either import modules from either side or create buttons and shift your control to each side.
- You can create a button in RN and call Native module or complete project. please have look at this link
https://facebook.github.io/react-native/docs/communication-ios.html
Hope this helps. I will be most probably developing a project which allows you to bridge 2 apps by one button with complete documentation.
Update: looks like this is implemented now with IntentAndroid! https://facebook.github.io/react-native/docs/intentandroid.html#content
-- original post --
I am writing an Android app with React Native. I would like to display a hyperlink that will launch the user's default browser and open the linked URL. How can I do this?
There is LinkingIOS for iOS apps, is there some equivalent for Android?
Or am I going to have to create a component that wraps something like this (Java):
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
OK it looks like what I wanted isn't a react component just yet, but I found this awesome component that is exactly what I want: https://github.com/ivanph/react-native-webintent/
