App navigation in React Native : maximum call stack size exceeded - ios

Question

I'm using ReactNative to create an iOS app. But I encountered an error I don't know how to fix.
I wanted to create a button for navigating to another scene. I followed Dark Army's tutorial on RN navigation and used the source code provided. I double checked everything and all seemed fine. But the error I mentioned pops up.
Here's the code I have done so far:
Index.ios.js:
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
} from 'react-native';
var Navigation = require('./DARNNavigator');
class QayProject extends Component {
render() {
return (
<Navigation></Navigation>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#FFF5E7',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
AppRegistry.registerComponent('QayProject', () => QayProject);
DARNNavigator:
'use strict';
import React , {Component} from 'react';
import{
View,
Navigator
} from 'react-native';
const FirstPage = require('./FirstPage');
const SecondPage = require('./SecondPage');
class DARNNavigator extends React.Component{
constructor(props) {
super(props);
}
render() {
var initialRouteID = 'first';
return (
<Navigator
style={{flex:1}}
initialRoute={{id: initialRouteID}}
renderScene={this.navigatorRenderScene}/>
);
}
navigatorRenderScene(route, navigator) {
switch (route.id) {
case 'first':
return (<FirstPage navigator={navigator} route={route} title="FirstPage"/>);
case 'second':
return (<SecondPage navigator={navigator} route={route} title="SecondPage"/>);
}
}
}
module.exports = DARNNavigator;
FirstPage:
import React, { Component } from 'react';
import{
View,
Navigator,
Button,
AppRegistry,
StyleSheet
} from 'react-native';
export default class FirstPage extends Component {
constructor(props) {
super(props);
this.state={ id:'first' }
}
render() {
return (
<View style={styles.container}>
<Button
onPress={this.props.navigator.push({ id:'second' })}
title="Next"
color="#FFB200"
/>
</View>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
module.exports = FirstPage;
SecondPage:
import React, { Component } from 'react';
import {
View,
Text,
Navigator,
StyleSheet
} from 'react-native';
export default class SecondPage extends Component {
constructor(props) {
super(props);
this.state={
id:'second'
}
}
render() {
return (
<View style={styles.container}>
<Text style={styles.title}>
Hello!
</Text>
</View>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
module.exports = SecondPage;

Answer 1

Don't use that library. They don't even have ONE single star on Github (not that it's the measure of a library's worth, I'm just saying there are more proven libraries available). The best and most straightforward I've found so far is "react-native-navigation" (https://github.com/wix/react-native-navigation). A lot of people like "react-native-router-flux" as well but I personally don't.
Sorry, I don't have time to read the code right now, I may later. But my suggestion for now is to try out react-native-navigation. It's seriously amazing.

I suggest to follow the official guide of React Native and use the built-in Navigator component.
Using Navigators React Native
I never saw that error, but if it will come after a lot of navigation steps, you should take a look at the resetTo function. It will clear the navigation stack. This makes sense for example when you are navigating back to the home screen of your app.
