推荐答案
我个人发现试图使自动布局约束感code（以及使用NSLayoutConstraint）是相当混乱，很难理解。 VFL（可视化格式语言）是强大的，但我会建议，如果你是刚刚开始接触，然后自动布局故事板的工作或XIB文件可能会更容易（取决于你个人的preference）。
Personally I find that trying to make sense of Auto Layout constraints in code (and using NSLayoutConstraint) to be quite confusing and difficult to understand. VFL (Visual Format Language) is powerful but I would recommend if you are just starting out with Auto Layout then working in Storyboard or a XIB file may be easier (depends on your individual preference).
由于这是一个相当复杂的话题我已经把在学习基础知识很有帮助。
If you are just getting started with Auto Layout you may find the following presentation I made helpful in learning the basics.
下面是来自不同的模拟器了三个截图，显示了如何布局自动调整取决于屏幕尺寸：iPhone 5S，iPhone 6，和iPhone 6加：
Here are three screenshots from different simulators which show how the layout adjusts automatically depending on the screen size: iPhone 5s, iPhone 6, and iPhone 6 Plus:
从技术上讲，横向也被这些约束支持，但结果可能会或可能不适合您的要求。 （我不确定什么方向你计划的支持。）
Technically, landscape orientation is also supported by these constraints however the result may or may not fit your requirements. (I am unsure what orientations you are planning to support.)
