Cocoa Autolayout:内容拥抱与内容压缩阻力优先级 [英] Cocoa Autolayout: content hugging vs content compression resistance priority
问题描述
我在 Apple 文档中找不到关于 Cocoa Autolayout 内容拥抱和抗压缩性区别的明确答案.
I can't find a clear answer on Apple documentation regarding Cocoa Autolayout about the difference between content hugging and compression resistance.
有人能解释一下它们的用法和区别吗?
Can somebody explain their usages and difference ?
推荐答案
概念总结:
- 拥抱 => 内容不想增长
- 抗压性 => 内容不想收缩
例子:
假设你有一个这样的按钮:
Say you've got a button like this:
[ Click Me ]
并且您已将边缘固定到优先级为 500 的更大超级视图.
and you've pinned the edges to a larger superview with priority 500.
然后，如果 Hugging 优先级 > 500，它将如下所示:
Then, if Hugging priority > 500 it'll look like this:
[Click Me]
如果拥抱优先级
500 它看起来像这样:
If Hugging priority < 500 it'll look like this:
[ Click Me ]
如果superview现在缩小了，如果Compression Resistance优先级> 500，它看起来像这样
If the superview now shrinks then, if the Compression Resistance priority > 500, it'll look like this
[Click Me]
Else if Compression Resistance priority
500，它可能看起来像这样:
Else if Compression Resistance priority < 500, it could look like this:
[Cli..]
如果它不能像这样工作，那么您可能还有其他一些限制正在影响您的出色工作！
If it doesn't work like this then you've probably got some other constraints going on that are messing up your good work!
例如您可以将其固定到优先级为 1000 的超级视图.或者你可以有一个宽度优先级.如果是这样，这可能会有所帮助:
E.g. you could have it pinned to the superview with priority 1000. Or you could have a width priority. If so, this can be helpful:
编辑器 > 大小以适应内容
Editor > Size to Fit Content
