First iOS app for all iphone devices

Question

I'm trying to make my first iOS app in xcode 7 for iOS 9 and i want to make it for all the iphone devices like iphone 4,4s,5,5s,6.

Do i have to make a different xib file for each one of the iphone or there is a simple way to make it for EVERY iOS device also like iPad???

Answer 1

There's a magical thing called autolayout. And another thing called universal app

Answer 2

You Can do both in single storyboard first you have to choose Universal while creating project. You need to do autoresize or apply auto layout.

Answer 3

No, you shouldn't need to do device or resolution detection. iOS includes lots of features for adaptive user interfaces. See here for example: https://developer.apple.com/design/adaptivity/

Answer 4

您只需要在应用程序中使用自动布局概念，就会在网上找到大量用于自动布局和调整大小的文档。

Answer 5

您可以使用自动布局为所有设备制作一个应用程序，并使应用程序通用，并且在xcode 7和ios 9中使用新功能可以使用堆栈视图来执行此操作。
