Its showing

285 duplicate symbols for architecture arm64

Linker command failed with exit code 1 (use -v to see invocation)

Strangely, I can't seem to get Archive to work in XCode but the build succeeds without the errors on duplicate symbols and its running properly on simulator as well.Im getting this error only when im trying to make archive.

The Project is on React Native 0.56.0 ,podfile installed as well.

i have no idea whats

Would really appreciate any help or insight on this, been stuck at this for hours.

I need to pass some data form react native to both native android and ios.

How can I do that?

thank you,

import React from 'react'; import { TextInput, KeyboardAvoidingView, StyleSheet } from 'react-native';

import Colors from '../constants/Colors';

const QaTextInput = ({ style, minWidth, maxWidth, placeholder }) => { const input = { height: 35, minWidth: minWidth, maxWidth: maxWidth, borderWidth: 1, borderColor: Colors.input, backgroundColor: Colors.input };

return (
    <KeyboardAvoidingView
        behavior="position"
        keyboardVerticalOffset="100"
        enabled>
        <TextInput
            placeholder={placeholder}
            autoFocus={true}
            showSoftInputOnFocus={true}
            style={input}
        />
    </KeyboardAvoidingView>
);

};

export default QaTextInput;

I am working on a React Native application and whenever I try to build the application I am encountering these errors. I know there are many similar questions on this matter but the solutions given there are not working for me.

I have searched but I am still stuck here. I have tried linking using react-native link. I have tried deleting the DerivedData folder for the application. Hence I have tried everything but can't seem to find a solution for this. So I turned to you guys please suggest any solution to fix this. Looking forward to your answers. Thank you in advance.

It seems to be a pretty common task to have an application-wide search bar in the header. Unfortunately, I haven't found some ready recipes on how to accomplish it the right way. My solution was to place a custom SearchBox component in the React Native Navigation header using headerTitle:

static navigationOptions = ({navigation}) => {
     headerTitle: () => (<SearchBox ... />)

It had its drawbacks, e.g. using "static" variables to pass state and behavior between the application and the component. But it worked so far. Now, after moving to RNN 4.1.1, it stopped working because of the specifics of how the header is implemented in the RNN:

TextInput now doesn't fill the header's width and doesn't handle the text input properly.

I am looking for a way to implement an application-wide search bar in RN, that features the following properties:

• it appears application-wide;
• its contents can be modified by a user, who wants to perform the search;
• when the user navigates back its contents conform to the shown page (e.g. if the user typed a query on page A and then got redirected to page B, so when they go back to the page A the search box contains "Page A" and not the query they typed);
• it supports suggestions (an also tricky thing to do).

Update

Ideally, I am looking for an answer that features the following aspects:

• be React Navigation v5 specific;
• tell how the search bar is implemented per se (e.g. passed as a component via header property in the above scenario);
• show how the search bar communicates with the core application in the following scenarios:
  • a user submits a query;
  • search box query gets updated independently from the application (e.g. the user taps a TouchableOpacity and gets navigated to a new page);
• how to ensure query consistency during the navigation. E.g. when the user goes back to the previous screen, the query in the search bar should match the screen contents.
• how to implement suggestions (users can see their options while typing; options are loaded online from the remote source).

How to set cipher suites for android and iOS in a react native application. Is there a native implementation needed?

I've created a React Native app using the XCode simulators which I'm now trying to test on an actual device. I've pushed my builds to Testflight and successfully installed it, however whenever I open the app and tap on the text input to enter my login details, the app closes instantly. I've installed the app on BrowserStack to get some more debugging information which gleaned this:

I've not been able to find out much about the Can't get most elevated app state from dictionary message other than this question, which doesn't seem relevant as I don't think I can deploy to TestFlight with a Developer certificate.

I have a problem is rendering correctly of this modal dialog when the keyboard appear on IOS OS.

But I have different effect when keyboard appear in Android and IOS, the android work well, like this

but on ios the effect is wrong, like:

I'm losing something?

Thanks for your time

Is there any package available to enable app lock in android and ios ?

I am exploring how to set-up a Universal link to an app. Hoping to jump right into my app when users enter the website. But due to business limitation, I can only create the .well-known directory that holds the apple-app-site-association json file under subdirectory like this:

https://localhost:8443/en/testing/.well-known/apple-app-site-association

From all of the tutorials I read online, it seems the .well-known directory must set up at the root directory of the domain but is it possible for me to create it in a subdirectory?

I have tried to setup a POC but seems Universal Links only works on https with non-self-signed ssl key. Please help. Thanks a lot.

I have upgraded Yarn to v2. I see that there is no node_modules folder anymore. But my Podfile is still looking for it. How can I fix it?

I am developing an App that verifies images based on their hash. I hash the images using this library "react-native-fetch-blob".

I store all the images taken inside the app, I am trying to allow users to be able to share the original uncompressed image.

Problem: When using React-Native Camera roll or React native Share to save the image to my local gallery, compression is performed which changes the hash of the image if I recalculate it.

What I want to do, is to be able to save the image to the users local gallery without compressing the photo?

Any help would be very appreciated. :)

I have run tests retrieving the photos back into the app (from the user's normal gallery) using React-Native-Image-Picker; However, I believe that also forms some compression on the image. I have also used react-native-fetch-blob to copy the photo from the user photo gallery back into the app.

Can provide code I used to generate the below results if anyone needs that.

I am building a react-native app which I do not intend to display ads but I have Firebase Authentication and other related services. To my surprise I keep getting this error below. What could have happen?

 *** Terminating app due to uncaught exception 
'GADInvalidInitializationException', reason: 'The Google Mobile Ads SDK 
was initialized incorrectly. Google AdMob publishers should follow 
instructions here: https://googlemobileadssdk.page.link/admob-ios- 
update-plist to include the AppMeasurement framework, set the -ObjC 
linker flag, and set GADApplicationIdentifier with a valid App ID. 
Google Ad Manager publishers should follow instructions here: 
https://googlemobileadssdk.page.link/ad-manager-ios-update-plist'

The way I found around this error is to update the info.plist by adding

<key>GADIsAdManagerApp</key>
 <true/>

This solved the error issue but not the fundamental problem which is why should it required GAD Application Identifier since ads will not be displayed in the app.

I Have ScreenA To Click Next ScreenB Then back To Screen A Not Call Function componentWillMount()

How to Reload Rout Screen in Back Action

Class ScreenA

import React from "react";

                this.setState({                  
                  dataSource: this.state.dataSource.cloneWithRows(data),

I'm adding firebase/admob to a RN app, i've added applicationId for both Android and IOS, Android works no problem i can see test banner, but IOS crash with this error :

I've added GADApplicationIdentifier in info.plist:

<key>GADIsAdManagerApp</key>
    <true/>
  <key>GADApplicationIdentifier</key>
  <string>my_application_id</string>

I am using a ScrollView inside of a PanResponder. On Android it works fine but on iOS the ScrollView will not scroll. I did some investigation and here are some facts:

1. If I put a break point in PanResponder.onMoveShouldSetPanResponder(), before I step over, the scrollView will scroll as normal but once I release the break point, the scrollView stops working.

2. If I modify ScrollResponder.js, and return true in scrollResponderHandleStartShouldSetResponderCapture() - it used to return false at runtime; and return false in scrollResponderHandleTerminationRequest(), the scrollView works OK but of course, since it swallows the event the outer PanResponder will not get the event.

So the questions are:

1. I want to make the scrollview to work, and not to swallow the event. Any one know what's the approach?
2. How the responding system works on iOS? The react-native responder system doc does not explain that to me.

I have the following issue when trying to compile my app for iOS on my CI (Bitrise). All the commands work perfectly fine locally.

Does anyone have an idea what might be an issue? I've tried compiling it on different XCode versions but always ends up in the same way (on CI only).

I am building an app in React Native, and was wondering if I could check to see if another app is installed on the user's device. Is it possible, or is there a 'permission' that I could prompt user for in order to have access to this?. Thanks !
