React-native-navigation: "RNNCustomViewController.h" file not found

[MyGuySi]

Issue Description

I've just started a new react native project from scratch and added RNN V2. I'm getting 'RNNCustomViewController.h' file not found from AppDelegate.m. I've searched the repo for any mention of that file but can't find it anywhere. Am I missing something?

Hi @MyGuySi,

I'm currently struggling with similar issue. The file you mentioned above can be found here.
Please check if it appears under node_modules/lib/ios. If not, please remove node_modules and try installing once again. It helped me, but I got stuck at next step during the linking process -

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RNNCustomViewController", referenced from:
      objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Please tell me if you were able to link the library.

@MyGuySi moving to https://discordapp.com/invite/DhkZjq2 with the issue, seems to be a more appropriate place for this type of questions :)

@marysieek I can see the file in that directory but it doesn’t seem to be part of the RNN XCode project that we add to our own projects... can’t see it anywhere in XCode which would explain why it can’t be found

I'm having the same problem

Hey I solved it. Just drag the RNNcustomview .h and .m files into the home directory with Appdelegate. Working fine for me now

[MyGuySi]

@sajsanghvi it’s a temporary fix but not sure that’s how we should be doing it. It needs to be part of the RNN project that gets added when integrating

This file is an example for custom native ViewController. You should not have this in your AppDelegate
Remove those lines:

#import "RNNCustomViewController.h"

[ReactNativeNavigation registerExternalComponent:@"RNNCustomComponent" callback:^UIViewController *{
    return [[RNNCustomViewController alloc] init];
  }];

@MyGuySi @marysieek - were either of you able to resolve this issue?

I've tried adding RNNcustomview .h and .m files into the home directory with Appdelegate of Xcode, but the error persists.
