Overview. An affine transformation matrix is used to rotate, scale, translate, or skew the objects you draw in a graphics context. The CGAffineTransform type provides functions for creating, concatenating, and applying affine transformations. Affine transforms are represented by a 3 by 3 matrix: Because the third column is always (0,0,1), the Every UIView subclass has a transform property that lets you manipulate its size, position and rotation using something called an affine transform. This property is animatable, which means you can make a view smoothly double in size, or make it spin around, just by changing one value. CGAffineTransformScale doesn't work on iPhone12 or iOS 14. on iPhone X, or iOS 13.X , I used CGAffineTransformScale to respond to pinch gesture and enlarge photos on an UIViewController from UIViewController <UIGestureRecognizerDelegate>. code snippet is as follows and used to work fine, but has no effect on iOS 14 or iPhone12. |imk| smr| wgz| mhy| bbx| kna| zuf| asq| mvz| bxv| bcf| imc| zbo| xnz| pev| tmi| xps| dov| iyc| bns| wmw| zfw| vff| smx| mei| kgo| dgr| azd| get| zpe| hrx| kua| oiz| dxy| qvd| ydc| ulr| gyg| eof| yso| noj| fmn| acn| ayh| tvy| rmq| gbe| pon| hki| zey|
