On iOS, a React Native ScrollView uses a native UIScrollView.
|
|
On Android, it uses a native ScrollView.
|
|
|
|
On iOS, a React Native Image uses a native UIImageView.
|
|
On Android, it uses a native ImageView.
|
|
|
|
React Native wraps the fundamental native components, giving you
|
|
the performance of a native app, plus the clean design of React.
