Getting the correct bounds of UIViewController's view

I have an iPad-application. In landscape orientation the UIViewController's view actual width = 1024px and height = 768 - 20 (statusBar) - 44 (navigationBar) = 704px.

So I wanna get this [1024 x 704] size and I'm using self.view.bounds for it. It returns [748 x 1024], which is wrong! But when I rotate the screen twice (current -> portrait -> current), the view's bounds are correct - [1024 x 704].

The view was initialized like this:

- (void)loadView {
    self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
    self.view.backgroundColor = [UIColor lightGrayColor];
}

And bounds were get like this:

- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"bounds = %@", NSStringFromCGRect(self.view.bounds));
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    NSLog(@"bounds = %@", NSStringFromCGRect(self.view.bounds));
}

So the question is.. How can I get the correct view's bound in the very beginning?

If you want to get correct bounds of view in ViewDidLoad method, you can use Dispatch async with delay for it. See this example below:

DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
                // Get your bounds here
            }
