iOS: Toolbar background transparent and not changeable since iOS 26

[GitToTheHub]

Bug Report

Problem

When running the plugin in XCode 26 on an iOS 26 Simulator, the toolbar is not semi-transparent anymore and the background color cannot be set with the option toolbarcolor. Also the buttons have borders, which is eventually no issue, because it's a change by iOS 26 which is its new UI desing. Example:

iOS 18.5	iOS 26.2

The green background color seen here, is from the underlying web view, which shines through the transparent parts of the in-app browser to demonstrate, which parts of the in-app browser are transparent.

This layout issues happens with cordova-ios 7 and 8.

What is expected to happen?

The toolbar should be semi-transparent by default and be changeable by the option toolbarcolor.

What does actually happen?

The toolbar is transparent. The option toolbarcolor is ignored.

While we're looking at this code, it would be good if the toolbar obeyed the safe-area-insets at the bottom to prevent buttons being partially off-screen

[GitToTheHub]

Yes, I was thinking the same, that this should also be applied. I will make a PR, which resolves the background color issue and add safe-area-insets to the buttons. The buttons should be keep as they are for iOS 26.

The clipboard buttons are also a problem inside IAB ; I am working to figure out how to fix them.
It seems to be an authorization issue. Has anyone else experienced this? I'm no hope @GitToTheHub did you see that?

[GitToTheHub]

Can you explain what you mean? I don't know what you mean with "clipboard buttons".

[diogenesricardo]

A button with clipboard function. To copy a text for example. Maybe this command not working yet.
        document.execCommand("copy text ")

[GitToTheHub]

You can use the official Clipboard API. But this works only with https. I tested the clipboard functionality by creating an extra site on my website and adding a clipboard plugin for WordPress. It worked when using the in-app browser: cordova.InAppBrowser.open("https://manuelbeck.software/clipboard-test/", "_blank");. I tested it in the simulator.

I created PR #1099 which uses auto layout instead of manual layout so the system handles the safe areas.

[diogenesricardo]

Yes, works! The problem is the document.execCommand("copy text ").

Yes, works! The problem is the document.execCommand("copy text ").

I'd say clipboard issue is a separate issue and is out of scope of this documented issue.

Normally I'd suggest creating a separate issue, but I'd also say that the execCommand has been deprecated for some time, so if it's stopped working in iOS 26 it could be intentional by Apple. It shouldn't be used in any newer or modern code, especially for clipboard usage where there is a replacement API, which @GitToTheHub has confirmed to be working as expected.

[diogenesricardo]

Yes, I understand, I was just commenting on the origin of the problem. In my case, I import a JS file from a third party that I have no control over, and when I checked, it was using this deprecated command.

[GitToTheHub]

I think you have no other choice to use the newer API when the deprecated one does not work. This is no issue with this plugin. Otherwise you could overwrite document.execCommand and react on the copy by yourself.

[diogenesricardo]

Yes, thank you very much for everyone's help, although initially I thought it was the plugin but it's not related. Once again, thank you for your availability everyone. Merry Christmas and God became man and dwelt among us.
