问题描述
我有一个(可能是错误的)假设，即在 xib 中启用右边距指示器等同于在代码中使用 UIViewAutoresizingFlexibleLeftMargin 等等.
I was in an (probably false) assumption that enabling the right margin indicator in xib is equivalent to using UIViewAutoresizingFlexibleLeftMargin inside code and so on.
所以，我曾经根据这个快照思考:
So, I used to think according to this snapshot:
今天晚些时候，我不得不交叉检查，偶然发现 这个帖子.
Later today I had to cross check, and stumbled upon this thread.
还有苹果文档，标题为使用自动调整规则自动处理布局更改"的部分:https://developer.apple.com/library/content/documentation/WindowsViews/Conceptual/ViewPG_iPhoneOS/CreatingViews/CreatingViews.html
And also the apple documentation, entitled with the section with title - "Handling Layout Changes Automatically Using Autoresizing Rules" in this link: https://developer.apple.com/library/content/documentation/WindowsViews/Conceptual/ViewPG_iPhoneOS/CreatingViews/CreatingViews.html
所以我现在有了一个新的概念，即以编程方式设置自动调整大小掩码如何等同于 xib 设置:
So I now have a renewed concept in my mind as to how setting autoresizing masks programmatically would be equivalent to xib settings:
场景 1:仅设置 (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight) 相当于:
在 XIB 中?
场景 2:在代码中设置 (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin) 相当于:
Scenario 2:
Setting (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin) in code is equivalent to:
在 XIB 中?
我的 2 个更新的场景是否正确?我现在在我的理解中吗?
Are my 2 renewed scenarios correct? Am I right now in my understanding?
推荐答案
是的，Interface Builder 在某种意义上把它颠倒了"(或者 UIView，取决于你如何看待它).您引用的场景"是正确的.
Yes, Interface Builder has it "reversed" in a sense (or UIView, depending on how you look at it). Your cited "scenarios" are correct.
