I'm making an ios app and have used the forge api to render the model in the webview. I'm using React Native but i'm open to suggestions for objective-c too.
The problem i'm having is to render the model in offline mode. The app could download svf file and save on the phone's disk, but how can i load the file and render that in the webview? I find the A360 app can render the model in offline mode but not sure if it's rendered in webview. I also find the Autodesk.Viewing.FileLoader api, but couldn't figure out with it and i don't find an example. This is what I have tried:
var viewer = new Autodesk.Viewing.Private.GuiViewer3D(document.getElementById('MyViewerDiv'));
var filepath = '/Users/zheminzhang/Library/Developer/CoreSimulator/Devices/901B40DC-1DB6-4596-A24A-6D3FAA1EA5C5/data/Containers/Data/Application/925466F3-A623-416B-81A4-1EB62123AA66/Documents/RNFetchBlob_tmp/RNFetchBlobTmp_d0411119-5006-4529-8734-7e70764a309b.svf';
var options = {
doc: filepath,
env: 'Local'
};
Autodesk.Viewing.Initializer (options, function () {
viewer.start(options.doc, options);
// viewer.initialize();
// var fileloader = new Autodesk.Viewing.FileLoader(viewer);
// fileloader.loadFile(filepath);
});
Can anyone help please?
I happened to notice this post. I am not sure how useful it would be, just sharing what I have practiced with iOS + Forge Viewer.

I have a Flutter app that can view mp4 files from a URL. (Using a video controller playing directly from the URL.) I want the user to be able to share them if they wish. As best I can tell the file has to actually exist on the device so I have broken down the steps for now into download file, invoke share.
I'm using this guide: https://retroportalstudio.medium.com/saving-files-to-application-folder-and-gallery-in-flutter-e9be2ebee92a
I need to work on ios and android. The problem is that on ios neither the filename I get from the dio downloader nor the ImageGallerySaver seem to "work" when passed to the system ShareSheet.
I'm using the flutter extensions dio, share_plus, cross_file, image_gallery_saver as I've seen recommended in various places.
File saveFile = File(directory.path + "/$fileName");
developer.log("starting download...");
await dio.download(url, saveFile.path,
onReceiveProgress: (value1, value2) {
developer.log("got progress " + value1.toString());
setState(() {
downloadProgress = value1 / value2;
});
});
_permaFile = saveFile.path;
if (Platform.isIOS) {
var galleryResult = await ImageGallerySaver.saveFile(saveFile.path,
isReturnPathOfIOS: true);
developer.log("gallery save result = " + galleryResult.toString());
_permaFile = galleryResult['filePath'];
}
After getting a directory we use dio to download the file, do some log chirping, and then save the name to an object member called _permaFile.
Then the share button triggers:
void _shareAction() async {
final box = context.findRenderObject() as RenderBox?;
final files = <XFile>[];
if (_permaFile == null) {
return;
}
developer.log("sharing file: " + _permaFile.toString());
files.add(XFile(_permaFile!));
await Share.shareXFiles(files,
text: "Event",
// subject: "Subject for Event",
sharePositionOrigin: box!.localToGlobal(Offset.zero) & box.size);
}
This works on android device... after I download I hit share, and I can share the video to a third-party app like WhatsApp.
On ios the ShareSheet is invoked but when I share I only get the text "Event", not the video file that goes along with it.
Note that I have tried both results... setting the _permaFile to be what comes back from ImageGallerySaver but also just using what the dio downloader gives back.
Note also that the ImageGallerySaver seems to work: the video really does land and is there in the ios video lib. If I go into the Photos app I can share from there to WhatsApp and have the video get sent.
In each case I get errors like this:
[ShareSheet] error fetching item for URL:file:/var/mobile/Media/DCIM/100APPLE/IMG_0021.MP4 -- file:/// : (null)
[ShareSheet] error fetching file provider domain for URL:file:/var/mobile/Media/DCIM/100APPLE/IMG_0021.MP4 -- file:/// : (null)
[ShareSheet] error loading metadata for
documentURL:file:/var/mobile/Media/DCIM/100APPLE/IMG_0021.MP4 --
file:/// error:Error Domain=NSFileProviderInternalErrorDomain Code=0
"No valid file provider found from URL
file:/var/mobile/Media/DCIM/100APPLE/IMG_0021.MP4 -- file:///."
UserInfo={NSLocalizedDescription=No valid file provider found from URL
file:/var/mobile/Media/DCIM/100APPLE/IMG_0021.MP4 -- file:///.}
In order to test this further I built the share_plus demo app:
https://github.com/fluttercommunity/plus_plugins/tree/main/packages/share_plus/share_plus
I modified it to share videos to see what was different. The share plus example (sp_example) works for sharing videos that have been selected by the picker.
For this reason I think the problem is something I'm missing about ios video filenames/formats and possibly a built-in conversion step that happens.
Here are what the filenames look like that I see in my app:
dio download result:
file:///var/mobile/Containers/Data/Application/223BF2B9-DDF0-490E-932F-09D5F03B98B3/Library/Caches/test.mp4
ImageGallerySaver result:
file:///var/mobile/Media/DCIM/100APPLE/IMG_0019.MP4
This is what video filenames look like when they are picked and shared in sp_example:
/private/var/mobile/Containers/Data/Application/E5CB4D7C-6CDF-4AA2-8134-C4322ED7C886/tmp/trim.E6633D68-44E3-4853-A29E-A71AC95A0913.MOV
Note that it has been converted to MOV extension and the user gets trim step right in the picker that results in trim in the name.
For my purposes I don't want to go through the picker, the user is on the screen showing the video and they shouldnt have to repick, so where do I get the post-conversion ios filename that references what I just saved?
In case you guys don't know, there was a problem previously with this library not rendering local images on Android as well, but apparently it was solved. Now, I'm facing the exact same issue on iOS, with a difference that I can use static images like assets/src/assets/images/logo.png. But when the images start with something like file:///, storage://, ph:// it simply does not get rendered.
What I'm doing is trying to generate a PDF report file, which must be generated independently the user has an internet connection or not. That is the reason why I have to use local images.
The static image is the logo of the company, and the local image which is not getting rendered is an image saved to the phone's storage through Image Picker or Camera Roll. The React Native Image component displays the image perfectly, so I don't think I'm using a wrong path.
What I have tried so far:
Removing the file:/// or storage:// or ph:// from the beginning of the path string;
In some cases, when I save an image to the phone's library with Camera Roll, it will return a path that starts with ph:// but without an extension, such as .jpg or .png. I tried to put the extension manually, and still does not make any difference;
I tried to convert the image to base64 using rn-fetch-blob (with RNFetchBlob.fs.base64.encode(path)), but still got no success.
Devices:
iPhone SE with iOS 14 (also simulator iPhone 11 with iOS 15)
MacBook Air 2017 Core i5 1.8GHz and 8gb RAM (macOS Big Sur 11.5.2)
Environment
node: 12.22.7
npm: 6.14.15
react: 16.9.0
react-native: 0.61.5
react-native-html-to-pdf: ^0.11.0 (updating it to 0.12.0 also got me the same result)
Code:
sharePDF = async () => {
try {
this.changeVisibilityOptions(false);
this.changeVisibilityLoading('Gerando PDF...');
let htmlTemplate = '';
htmlTemplate = await getPDFDespesa(this.state);
const pdfOptions = {
html: htmlTemplate,
fileName: 'RelatorioDespesas',
directory: 'Relatorios'
};
let pdfFile = await RNHTMLtoPDF.convert(pdfOptions);
this.changeVisibilityLoading(false);
const shareOptions = {
title: 'Compartilhar com:',
url: `file://${pdfFile.filePath}`,
type: 'application/pdf',
failOnCancel: false
};
const ShareResponse = await Share.open(shareOptions);
} catch (error) {
this.setState({ visibilityLoadingScreen: false });
console.log('Error =>', error);
}
}
Final thoughts:
Well, since the code is stored at a private repository, I can't show the whole thing here for ethical reasons. But I'm doing my best to give you as much details as possible.
The output the code produces an almost complete PDF, with the only point that I see broken image icons where the images were supposed to be. For Android it works perfectly now.
I think this might be an issue related to WebView, since react-native-html-to-pdf uses WebView to generate the PDF from HTML code. I reached this conclusion after another developer at my job was trying to create a screen with a preview of the PDF before it could be shared got the very same problem for both Android and iOS. The library he used was react-native-webview.
Update with solution
Alright guys, after a long time of research, me and a colleague got to a solution which may not be the best but does what we expected.
First of all, one thing that was discovered is that we have to divide the problem in two, because we actually had two problems.
Images from react-native-image-picker: After a long time trying to find the problem which was preventing the local images from getting rendered, I tried updating the library to version 4.7.3 (latest version at that day) and did a number of required changes to the code, as the version we were using was considerably aged. Well, it happened to work out for my surprise, even with the response uri's format not being changed;
Images from #react-native-community/cameraroll: This one was a bit more complicated. It took me some time to realize that the iOS' PHAsset was not supported in the WebView or react-native-html-to-pdf (which uses WebView in background). So, after some research, me and my colleague found a workaround that lead us to a relatively easy solution. Basically we used react-native-fs to copy the PHAsset media file to a temporary directory, which would return a uri that started with file:// and could be rendered by WebView. That's the code we used to do this:
export default function getImageNameFromUrl(imageUrl = "") {
if (imageUrl) {
const splittedImageUrl = imageUrl.split('/');
return splittedImageUrl.pop();
}
return null;
};
export default async function copyAssetsFileIOSAndReturnURI(remoteURL = '', localURI = '') {
try {
if (remoteURL && localURI) {
const imageName = getImageNameFromUrl(remoteURL);
const imgPath = await RNFS.copyAssetsFileIOS(localURI, RNFS.TemporaryDirectoryPath+imageName, 0, 0);
return imgPath;
}
return null;
} catch (err) {
console.log(err);
return null;
}
}
I am trying to share image from gallery and want to get it in my ionic application. I have tried a lot but still not understanding this.
I have tried following plugins:
https://github.com/protonet/cordova-plugin-share-extension-helper
https://github.com/markmarijnissen/cordova-plugin-share
How to share content/data through other apps in an iOS app like we do in an Android app with Intent.ACTION_SEND?
http://www.technetexperts.com/mobile/share-extension-in-ios-application-overview-with-example/
https://github.com/LokeshPatel/iOS-Phonegap-app-share-extension
After some detailed analysis, this is what I could conclude:
In Android, you could just get your application added in the share list using cordova-plugin-intent as described in this SO Post. You can also achieve this by adding intent filter in the activity as described here
In iOS, this is bit tricky as there are no straight forward plugins or readymade solution available to achieve this. But the best possible link i could get related to adding app in iOS share menu is getting listed in share menu The link includes apple documentation to do this and also some tweaking in Info.plist to achieve this.
You can use this plugin https://github.com/wymsee/cordova-imagePicker
The usage has been described there. It gives you the path of the image.
You can use that path or read the imagefile to get base64 equivalent of it. e.g.
window.imagePicker.getPictures(
function(results) {
for (var i = 0; i < results.length; i++) {
createImage(results[i])
}
}, function (error) {
console.log('Error: ' + error);
})
createImage(fileURL){
var img = new Image();
img.crossOrigin = 'Anonymous';
img.src = fileURL;
img.onload = function(){
// processing
}}
I am using the Phonegap File API but am having trouble copying a file from one location to the other.
my targeted device is iOS(ipad)
my iOS version is 9.2.1
I am working on windows platform
I am using phonegap build
my requirement :
I am capturing a video and its getting saved in some temp folder by default here is the location where its getting saved (/private/var/mobile/Containers/Data/Application/2183897E-3660-4145-A822-76F5B763E48D/tmp/capture-T0x17e7cae0.tmp.avqBi2/capturedvideo.MOV)
So I just want to move this (capturedvideo.MOV) video to photo album location in my ipad
This is my code which i am trying to make it work.
function success(entry) {
console.log("New Path: " + entry.fullPath);
}
function fail(error) {
alert(error.code);
}
function moveDir(entry) {
var parent = document.getElementById('parent').value,
parentName = parent.substring(parent.lastIndexOf('/')+1),
newName = document.getElementById('newName').value,
parentEntry = new DirectoryEntry(parentName, parent);
// move the directory to a new directory and rename it
entry.moveTo(saveToPhotoAlbum, newName, success, fail);
}
Any help or working examples would be great.
Thanks

This is simply not possible on iOS, because Apple does not allow to move videos, images or any other files out of the app sandbox to other folders. The reason that the standard-camera on the iPad/iPhone is able to place pictures there is simply because this is a built-in feature that has special permissions which your third-party app will not be able to get.
This is of course only true as long as the device is not jailbroken.
For more infos, especially concerning the file-system layout and what you are allowed to store, you should take a look at the cordova-file-plugin Readme on Github:https://github.com/apache/cordova-plugin-file
When I use the Download method of the FileReference class, everything works fine on Desktop and Android, but I get an error on iOS.
This is the code:
var req = new URLRequest(url);
var localRef:FileReference = new FileReference();
localRef.download(req);
On iOS I'm getting an Alert:
Download Error
File downloads not supported.
I already tried to NavigateToUrl() and it asks save the file in Dropbox or another App.
How can I fix this error?
You shouldn't use FileReference on mobile (or AIR, in general, though it does open the Load/Save dialog on desktop so there can be some use there). You should instead use File and FileStream, which give you far more control over the file system.
In this case, you could try to use File.download() and save it to File.applicationStorageDirectory, but I don't know if it will have any difference since it extends FileReference.
What I generally do is use URLStream instead of URLLoader. It gives you access to the raw bytes of the file you are downloading and then use File and FileStream
So something like (and this is untested off the top of my head, though I have used similar in the past):
var urlStream:URLStream = new URLStream();
urlStream.addEventListener(Event.COMPLETE, completeHandler);
urlStream.load(new URLLoader('url');
function completeHandler(e:Event):void {
var bytes:ByteArray = new ByteArray();
urlStream.readBytes(bytes);
var f:File = File.applicationStorageDirectory.resolvePath('filename');
var fs:FileStream = new FileStream();
fs.open(f, FileMode.WRITE);
fs.writeBytes(bytes);
fs.close();
}
Now, obviously, there is a lot more you want to account for (errors, progress, etc). That should be enough to point you in the right direction, however.
It's possible to create a full download manager using this method (something I did for an iOS project two years ago), since you can save as-you-go to the file system rather than waiting until Event.COMPLETE fires (using the ProgressEvent.PROGRESS event). That allows you to avoid having a 500MB file in memory, something most devices can't handle.
