推荐答案

显然，SDK 1.4.2中存在一个错误. 当前版本(在编写此答案时)为1.7.5，此问题已解决.

Apparently, there was a bug in SDK 1.4.2 back in the day. The current version (at the time of writing this answer) is 1.7.5, which has this problem fixed.

您可以通过从 https://parse.com/docs/downloads 或通过Cocoapods: https://cocoapods.org/pods/Parse

You can update the SDK by downloading the package from https://parse.com/docs/downloads or via Cocoapods: https://cocoapods.org/pods/Parse
