Xcode图像属性检查器中对齐的目的是什么

Question

I was fixing a problem related to image aspect ratio so just discovered the alignment property in attribute inspector but don't understand it's purpose even after searching from the internet.

Any help regarding this alignment property will be highly appreciated.

Answer 1

It is identical to the UIImage's alignmentRectInsets property (which you would set in code by calling withAlignmentRectInsets(_:) ). This is useful because a UIImageView automatically acquires its image's alignmentRectInsets (under autolayout) and so you can position/size the image view with respect to the "edges" of its visible image rather then the actual boundaries of the view.
