iOS Status bar text and background color. How?

[bogong]

Hello all!
Is there any way to change text and background color in Qt for iOS application? All that I found hasn't been useful. In one cases - it's depricated by Apple in other way it's not working. Have anyone experience of changing it? I am seeking solution NOT from Info.plist. I need something to change it directly from application at runtime.

set your Window flag (QML or QWidgets) to (Qt.Window | Qt.MaximizeUsingFullscreenGeometryHint) that will cover the whole space of your iPhone, and you can define the background from your app.

You'll have to (eventually) manage the safe area manually.

@J-Hilk But what about text?

Issue closed. Solution is:

• Setup in Info.plist this value Set the UIViewControllerBasedStatusBarAppearance to NO in the plist

<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

• In main.qml set the flags for Window component

import QtQuick 2.12
import QtQuick.Window 2.12

Window {
    flags: Qt.Window | Qt.MaximizeUsingFullscreenGeometryHint;
    color: "red"
}

• Create Objective-CPP class and inside of it use this Objective-C code (The example of creating Objective-CPP/Objective-C class published here):

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

and for getting size of status bar use something like this:

float ObjectiveCClass::mStatusBarHeight(void) {

	return [[UIApplication sharedApplication] statusBarFrame].size.height;
}

Be aware of the previous version of code that switching status bar text marked deprecated, something like this deprecated:

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
