Always center UIView

Question

Hi,

I have a small UIView that should appear always in the center of the screen. This works great for portrait mode but does not in landscape.

To draw the UIView I use:

myView.frame = CGRectMake((visibleArea.size.width - MY_VIEW_WIDTH) / 2, (visibleArea.size.height - MY_VIEW_HEIGHT) / 2, MY_VIEW_WIDTH, MY_VIEW_HEIGHT);
myView.autoresizingMask = (
                            UIViewAutoresizingFlexibleTopMargin |
                            UIViewAutoresizingFlexibleBottomMargin |
                            UIViewAutoresizingFlexibleLeftMargin |
                            UIViewAutoresizingFlexibleRightMargin
                           );

Any ideas what might be missing?

Answer 1

Maybe you don't change the orientation of the status bar. If you don't do this, the device thinks that the orientation still portrait, not landscape.

Answer 2

Why not try

myView.center = controller.view.center

Answer 3

Is the app auto rotating?

I mean, what does your -[UIViewController shouldAutorotateToInterfaceOrientation:] method looks like? Do you have an initial and supported orientations in your Info.plist file?

Check also parent's view autoresizesSubviews property.
