问题 I have tried many attempts to get react-native-image-picker up and working with my RN app. I am using Expo and VS Code and am not running the app with Xcode or Android Studio.

问题 I want to make a border image to a View , similar to border-image in the css. How could I achieve it ? 回答1: I believe that if you use Styled Components (https://www.styled-components.com/) you can set it with CSS directly.

问题 Is it possible to access the whole Redux state inside the React Navigation's header title? The official docs says that the state corresponding to the navigation is accessible: static navigationOptions = { title: ({ state }) => `Chat with ${state.params.user}` }; But I wish to access other parts of my Redux state, with the title updating when that state updates.
