@react-native-community/image-picker-ios
React Native ImagePicker for iOS. It allows you to get information on:
- Can you use the Camera
- Can you record video
Getting started
Install the library using either Yarn:
yarn add @react-native-community/image-picker-ios
or npm:
npm install --save @react-native-community/image-picker-ios
You then need to link the native parts of the library for the platforms you are using. The easiest way to link the library is using the CLI tool by running this command from the root of your project:
react-native link @react-native-community/image-picker-ios
If you can't or don't want to use the CLI tool, you can also manually link the library using the instructions below (click on the arrow to show them):
Either follow the instructions in the React Native documentation to manually link the framework or link using Cocoapods by adding this to your Podfile
:
pod 'react-native-image-picker-ios', :path => '../node_modules/@react-native-community/image-picker-ios'
Migrating from the core react-native
module
This module was created when the ImagePickerIOS was split out from the core of React Native. To migrate to this module you need to follow the installation instructions above and then change you imports from:
import { ImagePickerIOS } from "react-native";
to:
import ImagePickerIOS from "@react-native-community/image-picker-ios";
Note that the API was updated after it was extracted from ImagePickerIOS to support some new features, however, the previous API is still available and works with no updates to your code.
Usage
Import the library:
import ImagePickerIOS from "@react-native-community/image-picker-ios";
Can you use the camera:
ImagePickerIOS.canUseCamera(canUseCamera => {
console.log("canUseCamera", canUseCamera);
});
Can you record videos:
ImagePickerIOS.canRecordVideos(canRecordVideos => {
console.log("canRecordVideos", canRecordVideos);
});

- Methods:
Types
OpenCameraDialogOptions
Describes the settings for the camera:
| Property | Type | Description |
| --------------- | ------------------------------------------------ | -------------------------------------------------------------------------------------------------- |
| videoMode

Methods
canUseCamera()
Executes a callback with the a boolean value stating whether or not you can use the camera.
Example:
ImagePickerIOS.canUseCamera(canUseCamera => {
console.log("canUseCamera", canUseCamera);
});
canRecordVideos()
Executes a callback with the a boolean value stating whether or not you can record videos.
Example:
ImagePickerIOS.canRecordVideos(canRecordVideos => {
console.log("canRecordVideos", canRecordVideos);
});
openCameraDialog()
Opens the camera dialog with the specified OpenCameraDialogOptions
and two callbacks, one for success and one for cancel.
Example:
ImagePickerIOS.openCameraDialog({
unmirrorFrontFacingCamera: false
videoMode: false
}, () => {
// success
}, (error) => {
// cancel
});
openSelectDialog()
Opens the camera dialog with the specified OpenSelectDialogOptions
and two callbacks, one for success and one for cancel.
Example:
ImagePickerIOS.openCameraDialog({
showImages: true,
showVideos: false
}, (imageUrl, height, width) => {
// success
}, (error) => {
// cancel
});
Troubleshooting
Errors while running Jest tests
If you do not have a Jest Setup file configured, you should add the following to your Jest settings and create the jest.setup.js
file in project root:
setupFiles: ['<rootDir>/jest.setup.js']
You should then add the following to your Jest setup file to mock the ImagePickerIOS Native Module:
import { NativeModules } from 'react-native';
NativeModules.RNCImagePickerIOS = {
canRecordVideos: jest.fn(),
canUseCamera: jest.fn(),
openCameraDialog: jest.fn(),
openSelectDialog: jest.fn(),
};
Issues with the iOS simulator
As your simulator doesn't have a camera, there is no way to open the camera on the simulator.
