React Native ios picker is always open

Use ActionSheet instead of Picker on iOS. https://facebook.github.io/react-native/docs/actionsheetios.html

As answered by jevakallio this is the default behaviour on iOS. But this doesn't give a good UX so remove all picker components and replace with ActionSheet.

I did and it works great. The reason I prefered ActionSheet over other components suggested by jevakallio because it is developed by the RN team and has a good native feeling. The last option suggested react-native-modal-picker is also very good.

That's just how the iOS UIPickerView component works - there's no way to customize it.

If you want a different kind of UI element, you'll need to write your own, or use one of the many open source libraries, such as:

• react-native-dropdown
• react-native-modal-dropdown
• react-native-modal-picker

Googling with these, and similar keywords, yields many other libraries as well.

I don't know why you'd choose the answer with ActionSheet as accepted answer.However I'll give a workaround for this problem:

Put this values in your state:

this.state= {    pickerOpacity: 0,    opacityOfOtherItems: 1 //THIS IS THE OPACITY OF ALL OTHER ITEMS, WHICH COLLIDES WITH YOUR PICKER.    label: 'Firstvalue'}

In your render method do following:

{this.checkIfIOS()}      <Picker         selectedValue={this.state.selected}         style={{ height: 50, alignSelf: 'center', opacity: this.state.pickerOpacity, marginBottom:30, width: 250}}         onValueChange={(itemValue, itemIndex) =>{            this.setState({                selected: itemValue,                label: itemValue            });            toggle();            }          }>          <Picker.Item label="Your Label" value="yourValue"/>      </Picker>

So now we've to check, whether our client is android or ios. Therefore import Platform and put the checkIfIos()-Method in your code:

import {Platform} from 'react-native'checkIfIOS(){        if(Platform.OS === 'ios'){ // check if ios            console.log("IOS!!!");            //this button will (onpress) set our picker visible            return (<Button buttonStyle={{backgroundColor:'#D1D1D1', opacity: this.state.opacityOfOtherItems}} onPress={this.toggle()} color="#101010" title={this.state.label} onPress={this.changeOpacity}/>);         }else if(Platform.OS === 'android'){ //check if android            this.setState({                pickerOpacity: 1 //set picker opacity:1 -> picker is visible.            });            console.log("ANDROID!!!");        }    }toggle(){    if(Platform.OS === 'ios'){        if(this.state.pickerOpacity == 0){            this.setState({                pickerOpacity: 1,                opacityOfOtherItems: 0 // THIS WILL HIDE YOUR BUTTON!            });         }else{             this.setState({                 pickerOpacity: 0,                 opacityOfOtherItems: 1             });          }     }}
