Here is something I'm struggling to find a solution. I have a picker inside a form in my app, but when the text inside it is too big it won't ellipsize on iOS. For example, this view on android:

Is displayed like this on iOS:

That is the issue in question! Bellow I'll describe something that I have done to try to workaround the problem and is presenting even another issue
====
After playing a lot with flex and widths I decided to try to override the renderButton prop and force the ellipsize by hand by setting a width in it. Here is my component as it is right now:
export default class PickerInput extends React.Component {
state = {
itemWidth: styles.deviceWidth * 0.85,
labelWidth: 0,
};
render() {
const { label, children, selectedValue, ...other } = this.props;
const style = {
flex: 1,
};
if (!selectedValue && styles.OS === "android") {
style.color = "rgba(51, 51, 51, .20)";
}
return (
<Item
picker
style={{
marginTop: 0,
}}
onLayout={e => this.setState({ itemWidth: e.nativeEvent.layout.width })}
>
{styles.OS === "android" || this.state.labelWidth ? (
<Label>{label}</Label>
) : (
<View
onLayout={e =>
this.setState({ labelWidth: e.nativeEvent.layout.width })
}
>
<Label>{label}</Label>
</View>
)}
<Picker
mode="dialog"
placeholderStyle={{ color: "#bfc6ea" }}
iosHeader={this.props.label}
iosIcon={
<Icon name="ios-arrow-down" style={styles.styles.colorGray} />
}
renderButton={buttonProps => {
// This only affects iOS. Copied from native-base's Picker.ios.js
const { onPress, text, picker, selectedItem } = buttonProps;
const textStyle = [picker.props.textStyle];
if (!selectedItem) {
textStyle.push(picker.props.placeholderStyle);
}
let width = this.state.itemWidth - this.state.labelWidth;
// Give some border
width -= styles.theme.isIphoneX ? 55 : 25;
return (
<Button
dark
picker
transparent
onPress={onPress}
style={{
justifyContent: "flex-start",
width: Math.max(5, width),
}}
>
<Text
numberOfLines={1}
ellipsizeMode="tail"
style={textStyle}
note={picker.props.note}
>
{text}
</Text>
{picker.renderIcon()}
</Button>
);
}}
selectedValue={selectedValue}
style={style}
{...other}
>
{children}
</Picker>
</Item>
);
}
}
As you can see, I wait until the item and the label are rendered, get their width and set the width of them button as the difference between the 2. It works (not perfect, but works around the issue), but then I have this difference between an iPhone 6 and an iPhone X (tested on appetize.io):
iPhone 6:

iPhone X:

So, even though the solution is working nicely (again, as a work around) on iPhone 6, the same fix on iPhone X made the item itself overflows (even though I'm giving even more border for it).
So, like I said in the beginning, the main issue issue here is the lack of ellipsize in the picker provided by native-base. If it is solved, my issues with my workaround won't matter. If you prefer that I describe something more or even open another issue for something not related here (e.g. the difference between iPhone X and iPhone 6) just ask!

Same issue :/
@bellini666 @andresmtz98
Where have you imported your Picker component from?
If you have imported it from "react-native", then it is already an issue with "react-native"...
If you have imported it from "native-base", Check if the issue doesn't persist after importing from "react-native", then we can check if the issue is exclusive to "native-base"
seems to be working fine in my example snippet

Closing the issue due to no response for a while...Hope your issue has been resolved.You can reopen the issue if you still feel the issue is exclusive to "native-base"...
@suvenduchhatoi I tried using the one from "react-native" but it doesn't work like the one in android. I will display the picker itself, so the issue is for sure here.
If you take a look at the description I wrote a snipped of my component. If you take the renderButton away from it (that I wrote as a workaround for the issue) it should display the issue. try to add a long text in the placeholder (e.g. "blab lab bla bbla bla bla")
Note that my snipped also has an iosIcon in it
Can you reopen the issue? I don't have permission to do so
@suvenduchhatoi taking a look at nativebase's code I just notice this: https://github.com/GeekyAnts/NativeBase/blob/master/src/basic/Picker.ios.js
That component basically tries to mimic the one from android for the ios. The problem is for sure in it!
@suvenduchhatoi I was able to reproduce the issue in a snack: https://snack.expo.io/B1HqvwrbE
The problem seems to happen when I add an iosIcon. If you remove it (and remove the renderIcon too) it will work just like you described
Here is a screenshot of it:

Note that the text doesn't respect the size of the parent (the card) to ellipsize. It should also consider the fact that it has an icon. Like I commented, if you remove the renderIcon it will ellipsize in the right place
@suvenduchhatoi so, can you reopen the issue? Just want to confirm with you so I don't have to open a new one
the same issue in iOS... need help...
Using style={{width:250}} within Button may be a fix at the moment. Yes, we will inspect why this is happening

@SupriyaKalghatgi I just tested the latest release (that seems to include the fix above) and it doesn't seem to fix the issue.
@bellini666 share package.json
did you try clearing cache once?
@SupriyaKalghatgi yes I did clear the cache. The app continues to look exactly like the screenshots from my first post: android works fine but long texts on iOS not ellipsize.

V 2.12.0 adds an ellipses but still pushes the caret off screen:

Fixed with commit e140084
hrm, I just saw the commit and, although I think it will fix my issue (still need to test it when a new release is out), I think it will not work on some cases since it is considering the window width. If there are 2 pickers in the same line (meaning that each one has a size of ~ 1/2 of the device's width), it will have the same problem. Unless I'm missing something here.
Ah, and that would happen also even for the default case of one picker per line if the horizontal margins are greater than 50.
Had same issue while placing 2 pickers in the same line (Grid->Row->(Col,Col)) . I fixed it by wrapping each picker inside Body
<Body style={{width:"90%"}}>
<Picker/>
</Body>
Havn't checked the result on Android though.
Hi @SupriyaKalghatgi the fix to the Picker in 2.12.1 breaks my screen and I had to downgrade back to version 2.11.0 as I could not find out how to fix the layout issue. I use a Picker inside a DeckSwiper and version 2.12.1 makes the Picker wider than the DeckSwipper width and once a value is selected it, the formatting becomes completely skewed (the trick from @itsakt <Body style={{width:"90%"}}>... did not work for me):
Version 2.12.1, the icon (orange) is behind the DeckSwiper to the right-hand side:

Version 2.12.1 once a value is selected:

The same in version 2.11.0, which is perfect:

The issue @mindfulnessforever had is probably related to my previous coment

This seems to be related to #2630
I'm having a similar issue. If you are using inline labels for your pickers, the picker values will lay on top of the picker label. And there really isn't a good way to fix this due to:
<Text style={[this.props.textStyle, { width: Dimensions.get("window").width - 50 }]} note={this.props.note} numberOfLines={1} ellipsizeMode="tail">
There is now no control over the pickers width. We've had to downgrade to 2.12.0 due to this regression.
@bnash2501 may like this we need
We've had to downgrade to 2.12.0 due to this regression too!
@SupriyaKalghatgi Can we get this reopened? This is the PR that broke the pickers: https://github.com/GeekyAnts/NativeBase/commit/e1400842a2e0d766ccb8cfb23b13f9423c737a36
As pearpai has pointed out, the width should be the first style property so it can be overwritten. Not everyone uses full width pickers.
I'm having the same issue on iOS. Is there a chance to get this fixed?
Why this is closed? The issue is still there in "native-base": "^2.12.1".
