在NSView层上设置仿射变换无法像在iOS上那样工作 [英] Setting affine transform on NSView layer not working as on iOS

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);
