支持所有iPhone尺寸

Question

I'm trying to create a iOS app, but I'm stuck on the layout.

I created the home view, but now I see that it's not shown in the right way in the 4S simulator.
I tried with size classes , but it looks like 4S and 6, for example, are in the same size class, and so I can't set a different dimension for views.

My goal is to support all devices, also iPads. Can someone please tell me how to do it?

Answer 1

尺寸类别主要用于iPad，Apple Watch和横向模式之间的分离。在potrait模式的iPhone 4至iPhone 6中，所有电话设备的尺寸均在同一类别中（常规高度和紧凑宽度）。自动布局具有许多不同的约束条件以帮助您适应界面在同一个班级中。您应考虑水平/垂直对齐，相等的宽度和宽高比约束。它们对于较小的尺寸更改非常灵活，可帮助您设计自适应布局。

Answer 2

You should use "Reset to Suggested Constraints" for all views in your View controller. You can also check the simulated metrics for all devices without compiling the the code. For 4s and 6 by default the size is Inferred. You should try resetting the constraints to check this for iPad as well.

Answer 3

I am just sharing an idea Option1: I think You can try adaptive Layouts and in file inspector->simulated Metrics->size-> Inferred. It works in all devices it supports both landscape and Portrait.

Option2: Go for Visual layouts they are easy to understand and they work perfect in all modes of Portrait.

Answer 4

I am think that you use code Instead design in main.storyboard ! for ex: create button with code (and use Ratio in your code)

by this way i create small app for iPhone & iPad !
