reactNativeNavigation.Navigation.startSingleApp is not a function

Question

I'm building a React Native app and using React Native Navigation to move between screens. Something happened, some files were deleted and it seems like my xcode project settings were wiped.

When I boot up my app using 'npm run start' and 'react-native run-ios --simulator="iPhoneX", I get the following errors:

• red error simulator screen that says: _reactNative.Navigation.startSingleScreenApp is not a function
• the terminal window I ran "run-ios" fails and has this error: Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_RNNCustomViewController", referenced from: objc-class-ref in AppDelegate.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I followed these instructions: https://wix.github.io/react-native-navigation/#/docs/Installing

versions:

• node: v11.6.0
• npm: 6.5.0
• react-native-cli: 2.0.1
• react-native: 0.55.3
• "react-native-navigation": "^2.2.5"

App.js:

import { Navigation } from 'react-native-navigation';

import AuthScreen from './src/screens/Auth/Auth';
import SequencesList from './src/screens/SequencesList/SequencesList';

Navigation.registerComponent("my-app.AuthScreen", () => AuthScreen);
Navigation.registerComponent("my-app.App", () => App);
Navigation.registerComponent("my-app.SequencesList", () => SequencesList);

Navigation.startSingleScreenApp({
  screen: {
    screen: "my-app.SequencesList",
    title: "Sequences"
  }
});

AppDelegate.m

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <ReactNativeNavigation/ReactNativeNavigation.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
  [ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];

  return YES;
}

Answer 1

setRoot({stack}) instead of startSingleScreenApp(params)

You are using a react-native-navigation version 2. check the API changelog
