Not running under iOS and Ionic when using "use:'file'" about canvascameraplugin HOT 11 CLOSED

from canvascameraplugin.

Hello,

The latest cordova-ios application uses wkwebview instead of webview. WKWebView doesn't allow local resource files loading (i.e. URLs such as file://...) from the loaded html file. However there are workarounds. I'll update you as soon as i find a suitable solution.

Thanks for your answer.

Btw... I have a question and kind of a feature request :)
Some ugly phones (ynwim) show a horizonatally front cam preview, i.e. you look into a mirror. Others show unflipped previews... closer to reality.

In my app I use the front cam for real time pattern recognition and have to know if the image is flipped or not. Currently, the user has to check it by himself in the apps configuration.

Do you see a chance to detect flipped video streams on the level of the plugin?

Best regards

Hello,

In the latest release the mirroring problem is fixed. However, I could not reproduce the bug you reported.
I implemented a fix, it works fine with our phone. Could you test the latest release and tell us if the problem still occurs ("Not allowed to load local resource...").

If it does, could you give us the iOS version you're using and the phone model.

Thanks,

Best regards

Any news ?

Hi Sami.

First: sorry for the late answer.
After some iOS-updates I tried it today with the latest version of your plugin and the option use:"file". The problem remains.
The device is an iPhone 5s with iOS 11.4.1.

Hi Sami.

I found the reason:
When running under iOS "use":"file" works only if using UIWebView.
Using the newer WKWebView leads to the "Not allowed"-error above. Seems, that this could be solved by rewriting "file://..." to "//...".
(My "fault": I am using Ionic, which uses WKWebView by default.)

Annother impact: using "use":"data" has the effect, that on a iPhone 5s the machine/app gets slower and slower and exits finally (after 20 minutes or so). Meanwhile the poor iPhone is close to its melting point :)
I have the feeling, the garbage collection is not fast enough to dispose outdated images.
This problem does not exist when using "file".

It woud be great, if you could detect UIWebView or WKWebView in your plugin and create the file-url accordingly.

Is there any progress on this issue? I'm having the same permission problem with WKWebView, using data kills my performance.

Hey Sami,

I saw your comment on #15 . I just wanted to let you know that it also doesn't work anymore on ios 12.2.
After updating my iphone 6s to 12.2, the plugin constantly throws this error. Using data is not really an option for the app I am developing.

If you need anymore information. I am available to provide it.

Hello,

It seems that Ionic is using as a default the Ionic Web View for Cordova plugin. According to its documentation the plugin changes Cordova default UIWebView to WKWebView.

According to previous messages :

It woud be great, if you could detect UIWebView or WKWebView in your plugin and create the file-url accordingly.

The latest version of the plugin implements exactly this solution. Checks if the cordova-plugin-ionic-webview plugin is in use, and rewrite the URL accordingly.

In conclusion, the bug should be fixed with the latest version.

Best regards.
