Question

如何使用react-native-share库和使用share.open()方法将图像从应用程序共享到instagram故事。

对于单个图像，使用 share.singleShare() 方法是有效的

const shareMultipleImage = async () => { 尝试{

  const instagramAvailable =  Platform.OS == 'android' ? await checkPackage() : await checkInstagramInstalled()
      if (!instagramAvailable) {
        const url = Platform.OS === 'android'
          ? 'https://play.google.com/store/apps/details?id=com.instagram.android&hl=en&gl=US'
          : 'https://apps.apple.com/in/app/instagram/id389801252';
        
        if (await Linking.canOpenURL(url)) {
          Linking.openURL(url);
        }
        return; // Stop execution if Instagram is not available
      }
  let localFilePaths = [];

  for (let i = 0; i < images.length; i++) {
    const { uri } = images[i];

    if (uri.startsWith('file:///')) {
      localFilePaths.push(uri);
    } else {
      const localFilePath = `${RNFS.CachesDirectoryPath}/image${i + 1}.jpg`;
      const downloadOptions = {
        fromUrl: uri,
        toFile: localFilePath,
      };

      try {
        await RNFS.downloadFile(downloadOptions).promise;
        localFilePaths.push('file://' + localFilePath);
      } catch (error) {
        console.log('Error downloading file:', error);
        // Handle error (e.g., skip this image)
        continue;
      }
    }
  }

  const shareOptions = {
    urls: localFilePaths,
    type: 'image/*',
  };

  await Share.open(shareOptions);

} catch (error) {
  console.log('Error sharing to Instagram:', error);

  if (error && error.message === "User did not share") {
    const url = 'https://www.instagram.com/';
    const supported = await Linking.canOpenURL(url);

    if (supported) {
      Linking.openURL(url);
    } else {
      console.log('Instagram not installed', 'Please install Instagram to continue.');
    }
  }
}

};
