Sparkle Always Up Date

Question

我最近在我的可可應用程序中添加了Sparkle Framework [http://sparkle-project.org/]。當我向Appcast.xml添加一個虛擬的新項目（版本1.1），並隨後嘗試從版本1.0進行更新時，它會顯示「XXX 1.0目前是最新版本」。

我一直在這裏一段時間，我已經閱讀了文檔[https://github.com/sparkle-project/Sparkle/wiki]很多次，沒有成功。

這裏是我的Info.plist：

<?xml version="1.0" encoding="UTF-8"?>

謝謝！

此外：思考更多，應該導致行爲不同於「你已經是最新的」？我覺得會，但我不確定。

Answer 1

Sparkle將appcast中的sparkle：version屬性與plist中的CFBundleVersion（這是機器可讀版本）進行比較。

所以，在這裏，你的CFBundleVersion（100）表明你有一個更新的（> 1.0）版本，這是什麼在appcast。

另一方面，CFBundleShortVersionString（對應於cast中的sparkle：shortVersionString）用於「用戶可顯示」版本。

Answer 2

我建議堅持使用Major.Minor.Batch（0.4.12）版本控制，並將它們與應用程序強制轉換和項目本身的info.plist文件（CFBundleShortVersionString）保持一致。 你也可以嘗試與旌宇http://amtourky.me/2016/01/20/mac-os-x-continuous-delivery-sparkler-the-missing-build-server-for-sparkle/
