Im using react native expo and im getting this issue:

[Unhandled promise rejection: TypeError: null is not an object (evaluating 'TrackingTransparency.requestTrackingPermission')]

Any idea on how to fix it?

I am encountering the following error when attempting to build my React Native app after adding the react-native-tracking-transparency package --

I've been trying to solve this for awhile now and am sure it is probably something simple, but I can't find the solution and searching online hasn't yielded many answers. How do I make my app build correctly while using this package?

Steps followed:

1. yarn add react-native-tracking-transparency
2. yarn install
3. cd ios
4. pod install

It perfectly works on simulator with debug variant but not on real device with production variant.

any suggestion ?

I'm running iOS 14.4 on an iPhone 12 Pro Max and for some reason when I try to request the tracking transparency permission using this library I always get 'denied' back and there is no dialog alert that appears that requests the permission.

I've toggled on and off the Tracking permission in the iOS settings multiple times and uninstalled and re-installed my app several times with no luck. My app doesn't even appear in the list of apps that require tracking. I'm pretty stuck right now, but it seems like a lot of other people are having the same issue maybe?

Hi There,

I've installed this lib and well displaying the request Tracking, but the custom IDFA isn't showing up

This is my code:

import {
  getTrackingStatus,
  requestTrackingPermission,
  TrackingStatus,
} from 'react-native-tracking-transparency';


getTrackingStatus()
      .then((status) => {

        if (status !== 'denied' && status !== 'authorized') {
          this.requestPermissions();
        }
        else {
          this.setState({
            trackingState: status
          });
        }
        
      })
      .catch((e) => Alert.alert('Error', e?.toString?.() ?? e));

Any help please !
Regards

When i build the app and i'm getting this issue:

Build input file cannot be found: '/Users/ejiang/Project/TKPro/TKPro-mobile/packages/tkp-mobile/node_modules/react-native-tracking-transparency/ios/TrackingTransparency.mm' (in target 'TrackingTransparency' from project 'TrackingTransparency')

If i fix the '.mm' to '.m' in the file(/ios/TrackingTransparency.xcodeproj/project.pbxproj),it will build success.But in production，i can't fix this file.

Is there any other idea to fix it?

After installing the package and adding NSUserTrackingUsageDescription to my Info.plist I get an error "[TypeError: null is not an object (evaluating 'TrackingTransparency.getTrackingStatus')]" when calling getTrackingStatus(). Same happens with requestTrackingPermission().

I am experiancing this issue only when testing on a real device. On emulator it works fine.
My guess is that it appears because on the emulator the "Allow Apps to Request to Track" option in "Setting -> Privacy -> Tracking", is configurable, while on my physical device it stays "greyed out".

There are a couple discussions/threads about this greyed out buttons but nothing seams to make them interactable.
One workaround is to wrap the function call in a try catch block and if an error occurs, treat it as "not-determined".

Is this the expected behaviour or am I missing something?

Device: iPhone 8 (iOS 14.5)

Hello,

I've tested in iOS 15 as it was officially released in 2021/09/20

However when calling method from iOS 15 requestTrackingPermission() I receive not-determined.

The same code executed in iOS 14 is working properly.

Do you have any idea why it's not requesting?

Thanks

import React, { useEffect } from 'react';
import { View } from 'react-native'
import {  requestTrackingPermission } from 'react-native-tracking-transparency';

const requestPermission = async () => {
    const trackingStatus = await requestTrackingPermission();
    alert(`trackingStatus ${trackingStatus}`);
}

const App = () => {
   useEffect(() => {
      requestPermission();
   }, []); 
   return <View />;
};

export default App;

I would like to show the requestTrackingPermission modal after denied the first time. It only works the first time when the status is not-determined

Hey @mrousavy
Thank you for the library.
Can you tell me what happens if the user clicks on 'Ask App Not to Track'. I tried it but its normally using the locations which was not supposed to.
Thank you

requestTrackingPermission returns 'denied' status without check for answer from modal.

requestTrackingPermission()
.then(trackingStatus => {
console.log('requestTrackingPermission', trackingStatus); // here shows "requestTrackingPermission denied"
});

hi! does this package support apple tv, for react-native-tvos?
thank you!

I am trying to run my react-native project in Xcode(ios) and I am faced with this error (run in real iPhone) :

Link react_native_tracking_transparency (arm64) 0.2 seconds * Undefined symbol: _RCTRegisterModule**
My project can run on Android, but on iOS, it could not run. I should mention that neither can run in the simulator nor on a real iPhone, and the strange thing is that I can archive it and I can do it via test flight. When I install the test flight application it works well, but I can not run the project.

I uninstall **react_native_tracking_transparency *** to see if the error is related to this package but as soon as I uninstall that, the same error(Undefined symbol: _RCTRegisterModule) *happens but with another package (react_native_spinkit), and I continue to uninstall also SpinKit package and again the error happens with another package. Also, it could not run in the previous Xcode version (13), when I updated my Xcode (14.1) for the first time after updating Xcode the app could run in Xcode, but then again the error happened and could not run the app.

my system config: Mac mini,chip apple M1,macOS:Ventura 13

Xcode: 14.1

react-native-cli: 2.0.1 react-native: 0.68.1

I tried different solutions but none of them works for me. Thanks in advance for any help from you.

After version of react-native-tracking-transparency (ATT) applied
Firebase Crashlytics reports crashes, such as attached images.
(FBSDKSKAdNetworkReporter.m line 92 / Fatal Exception: NSInvalidArgumentException)

I am currently using react-native-fbsdk-next. (FB SDK >= 9)
What should I do to fix the problem?
Thank you.

Hey am sorry to bother again but your advice is very valuable.

I want to change the tracking status when the user clicks a button but it seems the request prompt can be shown only once right? Is there any other way to change the status ?

Thank you

After installing the package the app works fine on iOS 14 but any version before that the app does not run.
I get this error.

dyld: Library not loaded: /System/Library/Frameworks/AppTrackingTransparency.framework/AppTrackingTransparency
  Referenced from: /Users/kash/Library/Developer/CoreSimulator/Devices/FE2B596E-88F2-43A5-8801-0EC1665C69E2/data/Containers/Bundle/Application/A96FC8FA-34BA-4322-86EE-860382C37B2A/jdwelreact.app/jdwelreact
  Reason: image not found

I found this solution on stack overflow. It's working for me now on all iOS versions, is this the right fixed? If so I think it should be added to the documentation, as I sadly released an update to the app store, and now all users on iOS < 14 the app is crashing for them. This is very important to mention.
Thank you

Includes app tracking transparency and is rigorously maintained and response 🤔 ?

Hey am sorry to bother again but your advice is very valuable.

I'm running iOS 14.4 on an iPhone 12 Pro Max[14.4],but it always has an error ：
Undefined symbols for architecture x86_64:
"OBJC_CLASS$_ATTrackingManager", referenced from:
objc-class-ref in libTrackingTransparency.a(TrackingTransparency.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
“Undefined symbol: OBJC_CLASS$_ATTrackingManager”

I try to change the build setting and build path to fix it，but it didn't work。

How can i do to fix it？

Thank you

Hi, thank you for your library. I've set up action inside my root component, to call prompt modal

It's very simple but anyway app crashed when requestTrackingPermission() triggered

`const onCheckUserTrackingPermission = useCallback(async () => {
try {
const trackingStatus = await getTrackingStatus();

  if (trackingStatus === 'not-determined') {
    return await requestTrackingPermission();
  }

  if (trackingStatus === 'authorized' || trackingStatus === 'unavailable') {
    return;
  }
} catch (error) {}

}, []);

useEffect(() => { onCheckUserTrackingPermission(); }, [onCheckUserTrackingPermission]);

Is there any way to change text what user see in modal window?
