Auto resize subviews on device rotation

Question

Hi there

I have all my subviews set up so that they are based on self.view.

EG: UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,(self.view.frame.size.width-20),(self.view.frame.size.height-90))];

however when the view rotates (shouldRotateToDeviceOrientation or whatever) the views all stay the same size. How can I make them change shape to fit? Can I do this automatically?

Thanks

Answer 1

you have to [view setAutoresizingMask:...]

Answer 2

Absolutely. Take a look at the autoresizingMask property. If you set your image view, in this case, to have an autoresizing mask of UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight, then when its parent view resizes (as it may or may not automatically do when your app rotates—you might have to set a similar autoresizingMask on the parent view), it'll maintain the exterior margins you set up for it.
