React Native 获得status bar的高度

Unfortunately, as of v0.34, the API to do this is still inconsistent across platforms. StatusBarManager.HEIGHT will give you the current height of the Status Bar on Android.

const STATUSBAR_HEIGHT = Platform.OS === 'ios' ? 20 : StatusBarManager.HEIGHT;

On iOS, you can use getHeight()

StatusBarManager.getHeight((statusBarHeight)=>{
  console.log(statusBarHeight)
})
