Screen rotate many time when change orientattion

Question

I have 2 screens: the first screen support all orientations, the 2nd screen just support landscape right orientation.
I want the first screen to save its orientation before pushing to the second screen and return to that orientation when it pops back from the second screen.

my code:

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[UIDevice currentDevice] setValue:@(currentOrientaion) forKey:@"orientation"];
    [UIViewController attemptRotationToDeviceOrientation];
}

it's work but sometime screen rotates many time to change orientation.
Someone help me: why is that?

Please try changing the following Target --> General and set Orientation Mode to Portrait only and Go To Target --> General and enable Requires fullscreen, I've followed [this](https://stackoverflow.com/questions/28938660/how-to-lock-orientation-of-one-view-controller-to-portrait-mode-only-in-swift) with above-mentioned settings to lock the orientation properly . — Sayooj, Dec 17 '19 at 09:03

You should call these lines in some other method like ViewDidLoad because for a specific view controller, viewWillAppear method may call multiple times.

Gaurav - ViewDidLoad is only ever called once, when the view is loaded, so anything you add there will only apply the first time you see the view. – Russell Dec 17 '19 at 09:02
So in what method should we call these lines. – Gaurav Malik Dec 18 '19 at 07:31
