Position React Native alert at bottom of screen - ios

React Native alert defaults to showing up at the center of the screen. I've been trying to style it so that it shows up at the bottom of the screen - with no success. Does anyone know how I would go about this? I tried position: absolute and bottom: 0 but it still shows up in the center.

I have tried this out let me know if it helps also have designed according to the image.
Copy Paste the code and try.

React-native-maps lite mode don't work at Ios emulator

Good afternoon everyone, I am developing an app in React native, I put the library react-native-maps to show some fixed maps in a scrollview, in android I show the coordinates with the marker but in the map moves when I try do the scroll

Hi while uploading the picture from iPhone using react-native-fs in my react-native app. I am getting below error.

keyboard is blocking TextInput field even when using KeyboardAvoidingView in React-Native

I'm Trying to input a value using TextInput but the keyboard is blocking the view. I configured KeyboardAvoidingView with padding so the elements are pushed up when the keyboard is active but my input field is still getting blocked entirely by the keyboard. I tried creating a parent view for the entire render method and wrapped my child views with KeyboardAvoidingView however this did not work either. Screenshots show the behavior.
Tested on iOS Emulator.

Button refuses to centre horizontally in container

I am trying to get a hang of React Native, but for some reason, I can't get the button to centre horizontally in view container.
export default class LoginScreen extends Component {
static navigationOptions = {
header: null,
}
render() {
return (
<View style={styles.container}>
<MKTextField
tintColor={config.colors.accent}
floatingLabelEnabled={true}
autoFocus={true}
textInputStyle={{color: config.colors.primary, height: 32}}
placeholder="Login"
style={styles.loginInput}
onTextChange={(text) => this.setState({text})} />
<MKButton
style={styles.button}
shadowRadius={2}
shadowOffset={{width:0, height:2}}
shadowOpacity={.7}
shadowColor="black"
onPress={() => {
console.log('hi, raised button!');
}}>
<Text pointerEvents="none"
style={{color: 'white', fontWeight: 'bold', alignSelf:'center'}}>
Login
</Text>
</MKButton>
</View>
);
}
}
const styles = StyleSheet.create({
loginInput: {
width: '100%'
},
logo: {
height: '25%'
},
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#fff',
paddingLeft: 16,
paddingRight: 16
},
button: {
backgroundColor: config.colors.primary,
borderWidth: 0,
height: 40,
justifyContent: 'center',
alignItems: 'center',
}
});
And here's what it looks like:
Can't really tell whats going haywire here!
In your style, you need to change alignItems to alignSelf
button: {
backgroundColor: config.colors.primary,
borderWidth: 0,
height: 40,
justifyContent: 'center',
alignSelf: 'center',
}

React Native showing blank screen

I'm using react-native latest release 0.4.4 and installed react-native-side-menu and react-native-carousel components.
For some reason when I run the app, it's not showing anything.
The code instantiate a view with sidemenu and contentview inside.
contentview is for displaying the main page which contains three buttons and when someone clicks on explore it takes them to search page using navigatorios component.
Is there is some problem with StyleSheet ?
'use strict';
var React = require('react-native');

var menu = <Menu navigator={navigator}/>;
return (

<ContentView/>

);
}
});
AppRegistry.registerComponent('Something', () => Something);
Am I doing something wrong here ??
I figured out that react-native-carousel component was conflicting with sidebar menu component and showing a blank screen. I posted the issue on their repository.
The simple solution is remove react-native-carousel component from everywhere, even from node_modules/, the folder inside.
Your react versions could be out of sync. I've had this happen to me when the react version bundled with the iOS app is different than the version that the packager is running.
If you're using cocoapods, make sure that the react version in your podfile is the same as your package.json.
