如何可以模拟IPhone应用程序升级过程中的SDK模拟器 [英] How can simulate the IPhone app upgrade process in the SDK simulator

问题描述

我工作的一个iPhone应用程序，并即将推出第2版。我们将改变核心数据模型，我想它发布给用户，并可能导致数据丢失之前，模拟仿真升级过程他们。似乎没有要上如何做到这一点在沙箱中的任何真正的好doucumentation释放它。

I'm working on an iPhone app and about to release version 2. We'll be changing the core data model and I'd like to simulate the upgrade process in the simulator before releasing it to users and potentially causing data loss for them. There doesn't seem to be any real good doucumentation on how to do this in a sandbox before releasing it.

推荐答案

我已经在过去使用的过程中一直擦去模拟器的工作版本，从检查出我的应用程序的previous我的版本库，编译和安装，使用它了一下，然后编译并安装应用程序的新版本。新版本的安装应模拟升级过程中，在那里你可以测试你的数据迁移到新的模式。

The process I've used in the past has been to wipe any working version from the Simulator, check out the previous version of my application from my repository, compile and install that, work with it for a bit, then compile and install the new version of the application. The installation of the new version should simulate the upgrade process, where you can test your data migration to your new model.

我也重复设备上的这个过程，以确保没有问题，遇到有两种。

I also repeat this process on the device to make sure no problems are encountered there either.
