I'm trying to create a custom alert dialog with an image background and some custom styling, but can't seem to find out how to do this using Alert or AlertIOS in react-native. Is this possible, or is there some library that can help me out?
Both Alert and AlertIOS utilise each platform's native simple alert dialog. On iOS the underlying native component is simplistic and only accepts a title, message, and buttons, with a similar case on Android.
For a more custom approach you could use React Native Modalbox, or React Native Modal - both of which provide a highly-customisable modal component.
In future I'd recommend using JS.coach for a comprehensive list of quality React Native components.
