推荐答案

Yes, myImageView.contentMode = UIViewContentModeScaleAspectFit;

该属性继承自UIView.

UIViewContentMode

UIViewContentMode

指定视图在其大小发生变化时如何调整其内容.

Specifies how a view adjusts its content when its size changes.

typedef enum {
   UIViewContentModeScaleToFill,
   UIViewContentModeScaleAspectFit,
   UIViewContentModeScaleAspectFill,
   UIViewContentModeRedraw,
   UIViewContentModeCenter,
   UIViewContentModeTop,
   UIViewContentModeBottom,
   UIViewContentModeLeft,
   UIViewContentModeRight,
   UIViewContentModeTopLeft,
   UIViewContentModeTopRight,
   UIViewContentModeBottomLeft,
   UIViewContentModeBottomRight,
} UIViewContentMode;
