( Autoresizing mask ) flexible width of an image with fixed height

Question

I have been playing around with iPhone interface building using only code and not using IB.

Now I\'m facing the following problem:

How can I set an image to

Answer 1

Horizontally:

• Resize keeping fixed left/right margins: UIViewAutoresizingFlexibleWidth
• Keep size and same distance from the left: UIViewAutoresizingFlexibleRightMargin
• Keep size, stay centered: UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin
• Keep size and same distance from the right: UIViewAutoresizingFlexibleLeftMargin

Vertically:

• Resize keeping fixed top/bottom margins: UIViewAutoresizingFlexibleHeight
• Keep size and same distance from the top: UIViewAutoresizingFlexibleBottomMargin
• Keep size, stay centered: UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin
• Keep size and same distance from the bottom: UIViewAutoresizingFlexibleTopMargin

Combine one from the first section with one from the second with a |. For example, to have it resize horizontally and keep the same size and distance from the top vertically, you'd use UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleBottomMargin.

You can use other combinations to do some more tricky things, but those are the basics.

Answer 2

You probably want this:

[myImageView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];

That will keep the margins static and resize the width.
