我可以在运行时禁用特定子视图的自动布局吗? [英] Can I disable autolayout for a specific subview at runtime?

问题描述

我有一个需要以编程方式操作其框架的视图 - 它是一种文档视图，可以包装其内容，然后通过操纵框架原点在超级视图周围滚动和缩放.自动布局在运行时与此作斗争.

I have a view that needs to have its frame manipulated programmatically - it's a kind of document view that wraps to its content which is then scrolled and zoomed around a superview by manipulating the frame origin. Autolayout fights with this at runtime.

完全禁用自动布局似乎有点苛刻，因为它可以合理地用于处理其他视图的布局.看起来我可能想要的是某种空约束".

Disabling autolayout completely seems a bit harsh because it could reasonably be used to handle layout for the other views. It seems like what I might want is some kind of "null constraint".

推荐答案

我遇到了同样的问题.但是我已经解决了.
是的，您可以在运行时为特定的 UIView 禁用自动布局，而不是在 Xcode 4.3 及更高版本中默认设置的整个 xib 或故事板禁用它.

I had the same problem. But I have resolved it.
Yes, you can disable auto layout at runtime for a specific UIView, instead of disabling it for the whole xib or storyboard which is set by default in Xcode 4.3 and later.

在设置子视图的框架之前，将 translatesAutoresizingMaskIntoConstraints 设置为 YES:

Set translatesAutoresizingMaskIntoConstraints to YES, before you set the frame of your subview:

self.exampleView.translatesAutoresizingMaskIntoConstraints = YES;
self.exampleView.frame = CGRectMake(20, 20, 50, 50);
