本文介绍了在NSView层上设置仿射变换无法像在iOS上那样工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在努力实现非常简单的目标.我想改变图层的比例.但是，它似乎没有按预期方式工作.实际上，它根本不起作用.图层的比例保持不变.
I am trying to achieve something very simple. I would like to transform a layer's scale. However it does not seem to work as expected. In fact, it does not work at all. The layer's scale remains the same.
这是我的代码:
NSView *v = [[NSView alloc]init];
v.wantsLayer = YES;
v.frame = self.bounds;
float scale = 0.8f;
[v.layer setAffineTransform:CGAffineTransformMakeScale(scale,scale)];
[self addSubview:v];
如果我登录v的affineTransform属性，则会得到null.
If I log the affineTransform property of v I get null.
推荐答案
在OSX上尝试一下:
self.layer.sublayerTransform = CATransform3DMakeScale(scale, scale, 0.0f);
