How To Use RCT_EXPORT_MODULE React Native

Question

Can anyone explain how to use the macro RCT_EXPORT_MODULE from React Native to create custom react modules with a specific name that's not the class name?

The documentation says,

This takes an optional argument that specifies the name that the module will be accessible as in your JavaScript code

My class name is:

@implementation ReactCustomService

But I want to rename it to:

RCT_EXPORT_MODULE(@"CustomService")

But this doesn't work. When I do:

var service = NativeModules.CustomService;

nothing is returned. But if I did RCT_EXPORT_MODULE(), then NativeModules.ReactCustomService it works fine.

Any thoughts? I also tried RCT_EXPORT_MODULE("CustomService"), but that doesn't work either.

I'm on react-native: 0.40.0

Answer 1

pass the name without any quotation marks around, eg.

RCT_EXPORT_MODULE(CustomService)

that should work
