问题描述
一旦我的应用程序在 iTunes Store 中有可用的新版本，是否可以强制用户升级?
Is it possible to force the user to upgrade once there is a new version of my application available in the iTunes Store?
我目前正在处理一个应用程序.但是，每当我上传更新版本时，我都想强制升级，因为升级将具有更多功能，我想丢弃以前的版本.iPhone 默认情况下是否可以这样做，还是我必须编写自己的实现来检查当前版本并将其与商店进行比较?
I am presently working on an application. However, I want to force the upgrade whenever I upload a newer version, because the upgrade will have more features and I want to discard the previous version. Is this possible by default with iPhone or do I have to write my own implementation to check the current version and compare it to the store?
推荐答案
系统处理应用程序更新的唯一方式是提示用户更新在标准 AppStore 应用程序中可用.
此外，独立应用程序不知道可用更新，因此您需要实施您的 Web 服务，以便应用程序可以检查当前版本是否有效.
而且我不确定这是否符合 Apple 关于应用程序的规则，例如(虽然找不到证明链接)您不能上传应用程序的试用版.
The only way system handles updates of your application is prompting user that update is available in standard AppStore application.
Also, standalone application is not aware of available updates so you'll need to implement your web service where application can check if the current version is valid.
And I'm not sure if this conforms with Apple rules on applications, like (can't find proof-link though) you cannot upload trial versions for an application.
