UIImage 方面适合并对齐到顶部

UIImage aspect fit and align to top(UIImage 方面适合并对齐到顶部)

问题描述

It looks like aspect fit aligns the image to the bottom of the frame by default. Is there a way to override the alignment while keeping aspect fit intact?

** EDIT **

This question predates auto layout. In fact, auto layout was being revealed in WWDC 2012 the same week this question was asked

In short, you cannot do this with a UIImageView.

One solution is to subclass a UIView containing an UIImageView and change its frame according to image size. For example, you can find one version here.
