Set iOS device orientation programmatically. How?

[bogong]

Hello all!
Is there any way in QT set the device orientation programmatically or by force?

Hello,
add the following entry in the .plist file
<key>UISupportedInterfaceOrientations</key>
<array>
<string>UIInterfaceOrientationPortrait</string>
<string>UIInterfaceOrientationPortraitUpsideDown</string>
</array>

@Gerhard The key word in my message PROGRAMMATICALLY OR BY FORCE. It's mean from code, not from application settings.

@bogong you'll need to call objective c code, but it should be possible

from here:

UIInterfaceOrientation currentOrientation = [UIApplication sharedApplication].statusBarOrientation;
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:@"orientation"];    
[UIViewController attemptRotationToDeviceOrientation];

@J-Hilk I know it. I've tried it. The orientation after this code detecting like you set. But QML interface not redrawing. It's working perfectly when I am using it in native Objective-C/Swift but QML interface not redrawing even appeared signal about changed orientation. Only after phisical changing orientation it's wrking. I've already spent 2 weeks for finding cause of it.

@J-Hilk but never the less - thx for reply. If, not if, when I get success with it - will publish example. Going to get next iteration of this issue tomorrow.

Hello,I have encountered the same problem. May I ask if this problem has been resolved? I am unable to modify the device orientation of IOS

@bogong This is what I did for my program:

NSArray *array = [[[UIApplication sharedApplication] connectedScenes] allObjects];
UIWindowScene *scene = (UIWindowScene *)array[0];
UIWindowSceneGeometryPreferencesIOS *geometryPreferences = [[UIWindowSceneGeometryPreferencesIOS alloc] initWithInterfaceOrientations:value];
[scene requestGeometryUpdateWithPreferences:geometryPreferences errorHandler:^(NSError * _Nonnull error) { NSLog(@"%@", error); }];

Where value is one of

UIInterfaceOrientationMaskLandscapeRight
UIInterfaceOrientationMaskLandscapeLeft
UIInterfaceOrientationMaskPortrait
UIInterfaceOrientationMaskPortraitUpsideDown

Hope this helps.
