在iPhone 4.3.3中运行iOS 5应用程序

Question

我正在为iOS 5创建一个iPhone项目。我需要知道是否可以在iPhone 4.3.3及更高版本中运行该程序吗？

Answer 1

Are you using anything in your code that was introduced with iOS 5.0 & newer? (such as storyboards)

If your answer is yes, then you can't run it on 4.3.3.

If no, then you can set the minimum required version to 4.3.X ( and here's a tutorial you can use ).

Here is a related question ( and another one ) that may help you out a bit more.

Answer 2

IIRC, you can configure the simulator in xCode to emulate an earlier version of iOS so you can confirm whether or not it will work on 4.3.3. Have a look at the build settings for your project, you can change the target O/S. I'm not sure all versions are available by default though. You might need to download other versions to test.

Answer 3

You said you are using ARC. ARC will work with iOS 4.x, but not iOS 3.x. So ARC will not be a problem. Based on everything else you said about not using storyboards and everything being coded, you should be okay. If you click on a method in Xcode it should allow you to bring up the documentation, and in the documentation it will provide the iOS version that it was released for. Make sure that this it iOS 4.3.3 or lower.
