parse-platform - 对 ParseUser 或 ParseObject 使用 saveEventually() 而不是 save() 或 saveInBackground()

Question

查看 Parse 文档，有一个 saveEventually() 方法可用于代替 save() 和 saveInBackground()。

我可以在我的代码中的任何地方使用这个函数来代替 save 和 saveInBackground 这样我就不必担心用户在离线和在线之间切换，而且我不必在没有连接的情况下处理保存吗？使用这种方法有什么缺点吗？

Answer 1

根据 Parse 的 iOS guide :

Most save functions execute immediately, and inform your app when the save is complete. If you don't need to know when the save has finished, you can use saveEventually instead. The advantage is that if the user currently doesn't have a network connection, saveEventually will store the update on the device until a network connection is re-established. If your app is closed before the connection is back, Parse will try again the next time the app is opened.

所以你会使用 save如果保存完成后需要回调。我认为您可以根据您处理的情况使用两者。
