Parse platform ParseUI iOS和CocoaPods的链接器错误

我试图使用Parse构建一个应用程序，并想给ParseUI一个机会。我使用Cocoa pods导入了Parse的主SDK，它运行得很好。当我决定添加ParseUI时，遇到了问题

我尝试过一些事情，比如强制包含Parse.framework来链接ParseUI，但似乎没有什么帮助。我不是Cocoapod或XCode方面的专家，所以我不知道我是否有明显的遗漏

我试过可可豆0.35和0.36-beta-1。这是一个swift项目，所以我不知道这是否会导致一些问题。

您需要使用framework Bolts.frameworks。此框架是Parse SDK的一部分。另一件事是，对于Parse SDK的最新版本（现在是v1.6.2），您必须导入Parse/Parse.h、ParseUI/ParseUI.h或两者，具体取决于您使用的对象。

如果您需要有关安装de Bolts framework的更多信息，请告诉我！：）

bump，我也有同样的问题，我有各种各样的链接错误，添加“螺栓”框架修复了一切。为什么解析“快速启动”指令没有提到它？
