Xcode 6以编程方式自动布局? [英] Xcode 6 auto layout programmatically?

问题描述

我的问题在这张图片上:

My problem is on this image:

我在Xcode 6中遇到这个问题，我想知道是否有一种方法可以通过编程方式解决此问题...我想编写一个使我的视图控制器适应所有设备的代码...是否可能?? (我已经尝试过手动进行自动布局，但是我真的很糟糕)...

I have this problem with Xcode 6 and I would like to know if there is a way to solve this problem programmatically... I would like to write a code which adapt my view controller to all devices... Is it possible?? (I already tried auto layout manually but I am really bad)...

推荐答案

似乎您实施了过于严格的约束.正如我在屏幕截图中看到的那样，您可能已经为按钮和输入设置了很宽的宽度约束，而不是等宽或等距的间距.使约束更加灵活.首选>=，<=约束，等宽约束，前导/尾随约束.与严格的布局相比，您将需要更多的布局，但是您将获得真正的自适应布局.

Seems like you've implemented too strict constraints. As I see on screenshot, you've probably set a strong width constraint for your buttons and inputs instead of equal widths or equal spacing between each other. Make your constrains more flexible. Prefer >=,<= constraints, equal widths constraints, leading/trailing constraints. You will need more of them in comparison to strict ones, but you'll get a true adaptive layout.

要在视图之间灵活地保持相等的间距，您可能会发现间隔视图的概念很有用.简而言之，放置一个透明的UIView并为其设置一些约束.要了解更多信息，请阅读示例自动布局" 或

To get flexible equal spacing between views, you might find helpful a conception of spacer views. In short, place a transparent UIView and set some constraints to it. To know more, read apple docs. If you like videos more (like I do :)) - watch wwdc videos, they are great. For example, Auto Layout by Example or Taking Control of Auto Layout in Xcode 5.

以均等排列的按钮为例，请看以下屏幕截图: 这是通过设置一些复杂但可理解的约束来完成的:

As an example of equally arranged buttons take a look at this screenshot: This is done with a little bit complex, but understandable constraints set:

所有按钮彼此之间具有相等的宽度约束.所有间隔视图彼此之间具有相等的宽度约束.每个间隔视图都有对按钮或父视图的引线/尾部的前导/尾随约束.

All the buttons has the equal widths constraints for each other. All spacer views has equal width constraints on each other. Each spacer view has leading/trailing constrains to buttons or parent view leadings/trailings.

有了iOS 9，您还有更多选择:

With iOS 9 you have a few more options:

• 您可以使用UILayoutGuide
代替间隔视图
• UIStackView允许实现相同的布局而完全没有约束

• instead of spacer views you can use UILayoutGuide
• UIStackView allows to achieve the same layout with no constraints at all
