I have this very strange bug on my react-native iOS app, when I'm using NavigatorIOS (need it) : there is a 30 points zone on the left of the screen that is not touchable on the first touch (nothing happens on touchableHighlight or TouchableWithoutFeedback) in Listview elements for example...
When I use Navigator, no problem at all, it's specific to NavigatorIOS (and I need it in this part of the app), also tried without any style, same problem.
Haven't seen any github issue or discussion about this bug.
Edit :

I have yarn installed react-native-gesture-handler,I then cd'd into ios and pod installed. I then reran the react-native run-ios and still when I swipe nothing happens whatsoever. Im getting zero errors it just doesn't swipe whatsoever. Am i doing something wrong? I have tried to remedy this situation anyway possible and It just doesn't seem to swipe no matter what.
my code is as follows:
import React, {useState} from 'react';
import {
Platform,
View,
Text,
StyleSheet,
Image,
TouchableOpacity,
flatList,
} from 'react-native';
import Swipeable from 'react-native-gesture-handler/Swipeable';
const styles = StyleSheet.create({
container: {
padding: 20,
flexDirection: 'row',
backgroundColor: '#fff',
justifyContent: 'space-between',
alignItems: 'center',
},
text: {
fontSize: 18,
color: '#69696969',
},
icon: {
height: 30,
tintColor: '#69696969',
...Platform.select({
ios: {
tintColor: 'blue',
},
android: {
tintColor: 'red',
},
}),
},
separator: {
flex: 1,
height: 1,

});
export const Separator = () => <View style={styles.separator} />;
const LeftAction = () => {
<View>

} else {
starIcon = Platform.select({

}
return (

You need to link RNGH to RN
run react-native link react-native-gesture-handler
if this doesn't work maybe you don't have cocoapads dependencies
to install it
run cd <your-ios-code-directory> && pod install
Edit: it seems that if I comment out the line "this.setState({logged_in: true});", line 63, that I don't get the error. My guess is that something about the way I'm trying to change the content being displayed in the render function based on if the user is logged in or not is what is the cause of this error. Any ideas?
I've been making some slight progress in understanding some very basics of React Native, I feel like. Although my code might not be pretty, up until some recent additions it worked. I'm recieving an error message in the IOS Simulator that reads "Invalid data message - all must be length: 8". It unfortunately isn't giving me any specifics that I understand, such as linenumbers.
I sincerely apologise if this is a repost, I've been looking like crazy on google and stackoverflow to find a solution to this error but have been unsuccessful in my searches.
I've censored the url I've using in fetch since it is an adress for testing within the company in very early stages, but I am 99,99% sure that's not where the problem lies.

Edit:
Add toString() to error did the trick for me:
.catch((error) => {
AlertIOS.alert("error", error.toString());
})
I was also getting the same error while using ScrollView.
Took me 2 days to figure out the solution.
I wasn't importing ScrollView from react-native.
Check if you've imported the Picker or not. :)
While rendering a set of row components in ListView, my uri images seem not to be showing up at all. I have included Image in the react module. My custom component is the following:
var url = rowData.mediaGroups[0].contents[0].url;
if (url.indexOf('w=150') > -1)
{
url.replace("w=150", "w=500");
}
return <ArticlePreview
category={rowData.categories[0]}
key={sectionID}
heartText={'2.9k'}
categoryPress={this.onCategoryDetailsPress}
selected={false}
source={{ uri: url }}
text={rowData.title.toLowerCase().replace(' ','')}
onPress={this.onArticleDetailsPress} />
The component has multiple properties and is used throughout my app (and works there with link images). But for some reason the component just stopped working in the app for uri images. Not sure what to do. Here is the code for the component itself:
//component for article preview touchable image
/* will require the following
- rss feed and api
- user's keyword interests from parse In home.js
- parse db needs to be augmented to include what they heart
- parse db needs to be augmented to include what they press on (like google news)

The UI currently looks like this with not images (has black background):
Checked my rss feeds - some were unreliable resulting in messing with the way the images were being shown
I use ReactNative to develop my iOS APP,to realize the QRCode scanner function,i took the react-native-camera component which provide the barcode scanner function to my project.everything goes all right,but when i had succeed in recognizing a QRCode,next time i use the model,the screen just got frozen,seems like the app goes crashed. something interesting that as the screen is frozen,and once the model cancelled from the left button of navigation,The module can work properly.
I'm not sure whether it's a inner bug of NavigatorIOS,or just the bug of react-native-camera itself.
here is the QRCode component code:
'use strict';
var React = require('react-native');
var Dimensions = require('Dimensions');
var {
StyleSheet,
View,
Text,
TouchableOpacity,

var { width, height } = Dimensions.get('window');
var QRCodeScreen = React.createClass({

cancelButtonTitle: React.PropTypes.string,
onSucess: React.PropTypes.func,
onCancel: React.PropTypes.func,
},
getDefaultProps: function() {
return {
cancelButtonVisible: false,
cancelButtonTitle: 'Cancel',
barCodeFlag: true,
};
},
_onPressCancel: function() {
var $this = this;
requestAnimationFrame(function() {
$this.props.navigator.pop();
if ($this.props.onCancel) {
$this.props.onCancel();
}
});
},
_onBarCodeRead: function(result) {
var $this = this;
if (this.props.barCodeFlag) {
this.props.barCodeFlag = false;
setTimeout(function() {
VibrationIOS.vibrate();
$this.props.navigator.pop();
$this.props.onSucess(result.data);
}, 1000);
}
},
render: function() {
var cancelButton = null;
if (this.props.cancelButtonVisible) {
cancelButton = <CancelButton onPress={this._onPressCancel} title={this.props.cancelButtonTitle} />;
}
return (
<Camera onBarCodeRead={this._onBarCodeRead} style={styles.camera}>
<View style={styles.rectangleContainer}>
<View style={styles.rectangle}/>
</View>
{cancelButton}
</Camera>
);
},
});
var CancelButton = React.createClass({
render: function() {
return (
<View style={styles.cancelButton}>
<TouchableOpacity onPress={this.props.onPress}>

</TouchableOpacity>
</View>
);
},
});
var styles = StyleSheet.create({

},
cancelButtonText: {
fontSize: 17,
fontWeight: '500',
color: '#0097CE',
},
});
module.exports = QRCodeScreen;
And In another Component I push this qrCode to the new sence:
'use strict';
var React = require('react-native');
var {
AppRegistry,
StyleSheet,
Text,
View,
TouchableOpacity,
NavigatorIOS,
AlertIOS,
Navigator,
} = React;
var QRCodeScreen = require('./QRCodeScreen');
var cameraApp = React.createClass({
render: function() {
return (
<NavigatorIOS
style={styles.container}
initialRoute={{
title: 'Index',
backButtonTitle: 'Back',
component: Index,
}}
/>
);
}
});
var Index = React.createClass({
render: function() {
return (
<View style={styles.contentContainer}>
<TouchableOpacity onPress={this._onPressQRCode}>
<Text>Read QRCode</Text>
</TouchableOpacity>
</View>
);
},
_onPressQRCode: function() {
this.props.navigator.push({
component: QRCodeScreen,
title: 'QRCode',
passProps: {
onSucess: this._onSucess,
},
});
},
// onPressCancel:function(){
//
// this.props.navigator.getContext(this).pop();
//
// },
_onSucess: function(result) {
AlertIOS.alert('Code Context', result, [{text: 'Cancel', onPress: ()=>console.log(result)}]);
// console.log(result);
},
});
var styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#F5FCFF',
},
contentContainer: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
}
});
AppRegistry.registerComponent('Example', () => cameraApp);
Any answer will be helpful!
I think it's a inner bug of NavigatorIOS, or maybe just sth else wrong.
Blew is my code, it is ok.
'use strict';
const React = require('react-native');
const {
AppRegistry,
StyleSheet,
Text,
View,
TouchableOpacity,
Navigator,
} = React;
var QRCodeScreen = require('./QRCodeScreen');
const CameraApp = () => {
const renderScene = (router, navigator) => {
switch (router.name) {
case 'Index':
return <Index navigator={navigator}/>;
case 'QRCodeScreen':
return <QRCodeScreen
onSucess={router.onSucess}
cancelButtonVisible={router.cancelButtonVisibl}
navigator={navigator}
/>;
}
}
return (
<Navigator
style={styles.container}
initialRoute={{
name: 'Index',
}}
renderScene={renderScene}
/>
);
};
const Index = ({navigator}) => {
const onPressQRCode = () => {
navigator.push({
name: 'QRCodeScreen',
title: 'QRCode',
onSucess: onSucess,
cancelButtonVisible: true,
});
};
const onSucess = (result) => {
console.log(result);
};
return (
<View style={styles.contentContainer}>
<TouchableOpacity onPress={onPressQRCode}>
<Text>Read QRCode</Text>
</TouchableOpacity>
</View>
);
};
module.exports = CameraApp;
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#F5FCFF',
},
contentContainer: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
}
});
you can try Library react native qrcode
https://github.com/moaazsidat/react-native-qrcode-scanner. on me ,
its run. you can try . in ios and android.
I can't get this simple NavigatorIOS test to work. The console log in My View triggeres, and I can get it to render if I skip the NavigatorIOS component, and render MyView directly. However, when MyView is triggered from a component within the NavigatorIOS component, it won't render anything else than 'My NavigatorIOS test'.
var React = require('react-native');
var {
AppRegistry,
StyleSheet,
NavigatorIOS,
Text,
View,
} = React;
var navigation = React.createClass ({
render: function() {
return (
<NavigatorIOS
initialRoute={{
component: MyView,
title: 'My NavigatorIOS test',
passProps: { myProp: 'foo' },
}}/>
);
},
});
var MyView = React.createClass({
render: function(){
console.log('My View render triggered');
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Hello there, welcome to My View
</Text>
</View>
);
}
});
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
}
});
AppRegistry.registerComponent('navigation', () => navigation);
I had a similar problem. I added the following to my Stylesheet:
...
wrapper: {
flex: 1,
}...
and then gave the NavigatorIOS component the wrapper style. That fixed the issue.
Add the container style to NavigatorIOS, it needs to be flex:1 to show the child component properly ( I had the same issue).
I ran into the same issue, my mistake was in the styles :
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
}
});
I had to remove justifyContent and alignItems from there. Problem solved for me.
I had the same issue. Turned out I had to add some margin to the top of the view inside the MyView component.
Try this:
var React = require('react-native');
var {
AppRegistry,
StyleSheet,
NavigatorIOS,
Text,
View,
} = React;
var navigation = React.createClass ({
render: function() {
return (
<NavigatorIOS
style={styles.container}
initialRoute={{
component: MyView,
title: 'My NavigatorIOS test',
passProps: { myProp: 'foo' },
}}/>
);
},
});
var MyView = React.createClass({
render: function(){
console.log('My View render triggered');
return (
<View style={styles.wrapper}>
<Text style={styles.welcome}>
Hello there, welcome to My View
</Text>
</View>
);
}
});
var styles = StyleSheet.create({
container: {
flex: 1,
},
wrapper: {
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
marginTop: 80
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
}
});
AppRegistry.registerComponent('navigation', () => navigation);
I meet the same problem. For me, that is the style problem. I create and use a new style property containerNV for NavigatorIOS. That solved my problem.
var styles = StyleSheet.create({
containerNV: {
flex: 1,
backgroundColor: '#05FCFF',
}
});
I had a similar issue too (stupidly) as I'd given the NavigatorIOS a background colour, which meant it covered up the actual component inside it for some reason.
I had a similar issue when I use Navigator , and nothing help of up answers.
So I use this.forceUpdate(); to force Update in button press function
Had the same issue. Nothing was rendering inside my main screen. After 2 hours I decided to remove the <View> element I was wrapping my navigator with, and suddenly everything worked.
In a nutshell, I went from this:
<View>
<NavigatorIOS
style={styles.container}
initialRoute={{
component: MainPage,
title: 'MainPage',
}}/>
</View>
to this
<NavigatorIOS
style={styles.container}
initialRoute={{
component: MainPage,
title: 'MainPage',
}}/>
