如何安装ipa更新不破坏用户数据 [英] How to install ipa update without destroying user data

问题描述

我想知道如何通过iTunes安装IPA，这只是一个更新的应用程序，我已经有了。我正在开发使用Flash CS5.5和AIR为iOS的应用程序。

I'd like to know how install an ipa through iTunes that is just an update to an app I already have. I am developing an app with Flash CS5.5 and AIR for iOS.

我可以在设备正常的应用程序 - 我只是把它放到应用领域在iTunes（库下），然后执行同步。但是，如果我有IPA的更新版本，我把它放到iTunes中，它不执行同步 - 我想这不认为是有区别的。

I can get the app on the device ok - I just drop it into the Apps area (under Library) in iTunes, and then perform a Sync. But if I have an updated version of the ipa, and I drop it into iTunes, it doesn't perform the sync - I suppose it doesn't think there is a difference.

我意识到我的可以的只是从我的设备中删除该应用程序，然后安装新的ipa。但我有很多来自本地存储在iPad上的应用程序用户保存数据，我不想消灭了这一点。

I realize that I could just delete the app from my device and then install the new ipa. But I have lots of user saved data from the app stored locally on the iPad and I don't want to wipe that out.

推荐答案

这是一个过时的歌曲，但我一直在寻找一个答案，这让...

This is an oldie, but I was looking for an answer to this so...

的技巧对我来说是改变版本，导出的ipa之前版本号。然后，如果你通过iTunes中添加应用程序，它会更新下次同步。没有删除是必要的。

The trick for me was to change the version and build number before exporting the ipa. Then if You add the app through iTunes, it will update on next sync. No deleting is necessary.
