My app drops when rendering CameraRollPicker. Show my code below. Is something wrong?

"react": "15.4.1",
"react-native": "0.39.2",
"react-native-camera-roll-picker": "^1.1.9"

import React, { Component } from 'react'
import CameraRollPicker from 'react-native-camera-roll-picker'

class CameraRollView extends Component {
  constructor(props) {
    super(props)
    this.state = { images: [] }
  }

  render() {
    return (
      <CameraRollPicker
        selected={this.state.images}
        callback={(images) => this.setState({ images })}
      />
    )
  }
}

I solved this problem. I must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data in my app's Info.plist.
