Can't save on iPhone, Safari about jspaint HOT 12 CLOSED

Yes, downloading on iPhone uses FileSaver.js, invoked with a blob. FileSaver.js then internally creates an a tag with a download attribute, then the download popup shows.

@DevJhns It may be a different version of Safari/iOS. Hopefully you can still save files tho if it opens in a new tab, with a long press on the image. Does that work?
JS Paint has File > Manage Storage by the way, if you didn't get it to save before.

I need to get on which iphone models and which ios versions this Download popup works

@DevJhns a[download] is supported from iOS/Safari 13.0 onwards: https://caniuse.com/#feat=download

I don't have an iPhone, so I'd have to get an emulator to test this, but: eligrey/FileSaver.js#324
looks like I might just need to update FileSaver.js

from jspaint.

Or it just doesn't work: eligrey/FileSaver.js#375

@evolveyourmind Do you get a new tab, or just nothing, or what?

from jspaint.

Saving on Safari/iPhone does actually work, users can choose to view/download the file (iOS 13.1.2).

Okay, great!

@christianliebel wow, great news!!!
Downloading on iphone works with filesaver.js or native saving from blobs?

from jspaint.

@christianliebel how you achieved this download pop up on iphone?
It works like in your photo on ipad, but on iphone all saved files open new tab (with blob url)

from jspaint.

@christianliebel thx for reply!
Yeah, I kinda get idea, how client-side blobs file saving works, except it doesn't work on Iphone, I can't get Downloads popup, file content opens in new safari tab with blob:45fc-... url
(but Downloads popup appears on Ipad, like on your photo in same situation)

something like this:

var blob = new Blob(receiveBuffer, {type: 'any/mimetype'});
a.href = URL.createObjectURL(blob);
a.download = 'filename.ext';

as I found out, this happens due to restrictions of iphone file system, but your image shows that this file managment works on iphone, how is this possible?

Does this file managment works only on iphone X and above?
Because I tried saving file from jspaint.app on iphone < X and nothing happened at all.
(with my script example above it opens file in new safari tab, not with safari file manager)

Yeah. problem that, I'm developing my own app, and this issue not related to jspaint actually, I need to download file (client side, from blobs) and it MUST be loaded in current tab, redirecting to other tab ruins all, and I don't want to store file on server, because file tranasfer happens peer to peer, soo all complicated, my app works everywhere except iphone (it opens file content in new tab, yeah file can be downloaded from new tab, but connection closes on redirect) so I need to get on which iphone models and which ios versions this Download popup works

thx for help!
