Part 1 - UIView's Content Mode

I decided to go down and learn every property for the UIView on the Attributes Inspector. Part of the whole "leave nothing misunderstood" quest.

Content Mode

I think most of us know how this applies to the UIImageView control but what about just the UIView?

This took a lot of digging to understand this property.

Here are some things I've found out but none of which actually came from Apple:

• For an image view, this is talking about the position/scaling of image.
• For a UIView that draws its content, this is talking about the drawn content.
  • Like using UIBezierPath to draw paths.
• It does not affect the layout of subviews inside a UIView.

How is this property beneficial?

• I won't go into how it is beneficial for a UIImageView. Most of you probably already know and if you don't then check out this great article.
• Use this property when drawing a path and then handling how that path is then positioned/scaled when the UIView's bounds or frame changes.
• The idea is to save processing time on redrawing when UIView's bounds change.
