Determine viewcontroller's view size dynamically on viewDidLoad - ios

Question

I've searched a lot about how can I determine the actual view size dynamically in the viewDidLoad method.
Here is my approach which seems to be work on both iOS6 and iOS7 with both Landscape and Portrait mode.
Is there a better solution for that?
Here is my code:
- (CGSize)actualSize {
CGFloat widht;
CGFloat height;
// Determin height and widht
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
if (orientation == UIDeviceOrientationLandscapeRight || orientation == UIDeviceOrientationLandscapeLeft) {
widht = kHeightSelfView;
height = kWidthSelfView;
} else {
widht = kWidthSelfView;
height = kHeightSelfView;
}
// Determin navigationbar height
CGFloat navigationBarHeight = self.navigationController.navigationBarHidden ? .0f : (MIN(self.navigationController.navigationBar.frame.size.height, self.navigationController.navigationBar.frame.size.width));
// Determin navigationbar height
CGFloat statusbarHeight = [DeviceCompatibility isIOS7] ? (MIN(SharedApplication.statusBarFrame.size.width, SharedApplication.statusBarFrame.size.height)) : .0f;
return CGSizeMake(widht, height - navigationBarHeight - statusbarHeight);
}

Answer 1

Typically you should only perform view-based geometry in viewWillAppear. Your view's frame is not yet set in viewDidLoad, but it will be set correctly before viewWillAppear is called.

Answer 2

Instead of picking height & width, you can pick the frame of view like this:
// Adjusts the frame of the child view.
CGRect frame = self.view.frame;
CGRect linkedFrame = scene.view.frame;
linkedFrame.origin.x -= frame.origin.x;
linkedFrame.origin.y -= frame.origin.y;
and then you can make them flexible so that they will resize properly :
// The scene's main view must be made flexible so it will resize properly
// in the container.
scene.view.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleHeight);
Let me know if this is not what you need :)
