Sparkle始终保持最新

Question

我最近将Sparkle Framework [ http://sparkle-project.org/ ]添加到了我的可可应用程序中。当我向appcast.xml添加一个虚拟的新项目(版本1.1)，然后尝试从版本1.0更新时，它显示“XXX1.0是当前可用的最新版本”。

我在这方面已经有一段时间了，我已经阅读了很多次文档[ https://github.com/sparkle-project/Sparkle/wiki ]，但都没有成功。

这是我的Info.plist：

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

和我的appcast.xml (重命名为Snappi.xml)：

谢谢!

另外:更多地思考这一点，这是否会导致不同于“你已经是最新的”的行为？我觉得它会，但我不确定。

Answer 1

Sparkle将appcast中的CFBundleVersion :version属性与plist中的版本进行比较(这是机器可读的版本)。

因此，在这里，您的CFBundleVersion (100)表示您的版本比appcast中的版本更新(>1.0)。

另一方面，CFBundleShortVersionString (对应于造型中的sparkle:shortVersionString )用于“用户可显示”版本。

Answer 2

我建议坚持使用Major.Minor.Batch (0.4.12)版本，并在应用程序转换和项目本身的info.plist文件(CFBundleShortVersionString)中保持相同。您也可以尝试这个与Sparkle http://amtourky.me/2016/01/20/mac-os-x-continuous-delivery-sparkler-the-missing-build-server-for-sparkle/无缝集成的轻松构建服务器
