Unable to set app orientation

[prawnydagrate]

I'm creating a game with KivyMD and it has resizing issues. Resizing works well on Linux, Windows, and macOS but on a phone, there's problems. For Android, I used plyer.orientation.set_portrait(). I could also specify the app orientation in my buildozer.spec file. But for iOS, plyer.orientation doesn't work. Is there any way I could specify the app orientation in my Xcode project or be able to set the orientation with Plyer? BTW, plyer.orientation works on Manjaro Linux.

I found

void export_orientation() {
    NSDictionary *info = [[NSBundle mainBundle] infoDictionary];
    NSArray *orientations = [info objectForKey:@"UISupportedInterfaceOrientations"];

    // Orientation restrictions
    // ========================
    // Comment or uncomment blocks 1-3 in order the limit orientation support

    // 1. Landscape only
    // NSString *result = [[NSString alloc] initWithString:@"KIVY_ORIENTATION=LandscapeLeft LandscapeRight"];

    // 2. Portrait only
    // NSString *result = [[NSString alloc] initWithString:@"KIVY_ORIENTATION=Portrait PortraitUpsideDown"];

    // 3. All orientations
    NSString *result = [[NSString alloc] initWithString:@"KIVY_ORIENTATION="];
    for (int i = 0; i < [orientations count]; i++) {
        NSString *item = [orientations objectAtIndex:i];
        item = [item substringFromIndex:22];
        if (i > 0)
            result = [result stringByAppendingString:@" "];
        result = [result stringByAppendingString:item];
    }
    // ========================

    putenv((char *)[result UTF8String]);
    NSLog(@"Available orientation: %@", result);
}

in my Sources/main.m file and was able to make my app all portrait.
