Async-storage: Brown Field integration

[DevArenaCN]

You want to:

I'm start to implementing a simple feature but got stuck on the iOS native side, I'm not an experienced iOS dev so bear with me on this.

What I need is a way on the native side read/write the Asyncstorage while keep the functionality on the React Native side (because the JS thread will be dead after the app is in the bg for a while)

Details:

What I've done:

1. #import <RNCAsyncStorage/RNCAsyncStorage.h>
2. in my native module, I have NSString *result = [[[RNCAsyncStorage alloc] init] _getValueForKey], but I got an error stating No visible @interface for 'RNCAsyncStorage' declares the selector '_getValueForKey'

Any idea how this should be implemented? Thanks!

Hey @DevArenaCN

You can have a look at brownfield integration docs for iOS

I've checked the brownfield doc, to my understanding even though I don't actually need to reinvent the wheels here, I'd still need to implement the delegate for every listed protocols, right?

[Krizzu]

Yes, that's correct

[DevArenaCN]

Gotcha, thanks for clearing that up for me.

[DevArenaCN]

Yes, that's correct

Another question, and it's been haunting me for a while now.?

 RNCAsyncStorage *asyncStorage = [bridge moduleForClass:[RNCAsyncStorage class]];
  asyncStorage.delegate = self;

I have there declared in my init for the delegate that I'm implementing, but I keep getting Use of undeclared identifier 'bridge'. I already imported RCTBridge, anything I did wrong?

Have a look at example app's AppDelegate

So I have get the example app locally and have it built and up and running, from the source code it seems like you could toggle the set/unset delegate via dev menu, however I didn't see it shown (cmd+d), should it be at another place?

Also, I've tried to set my delegate this way

 _testDelegate = [RNCTestAsyncStorageDelegate new];
  RNCAsyncStorage *asyncStorage = [bridge moduleForClass:[RNCAsyncStorage class]];
  asyncStorage.delegate = _testDelegate;

And it seems like the delegate wasn't set after all. Anything I did wrong?
