使用旧库时出现xcode错误

Question

我将我的Mac更新到1.9.4并安装了Xcode 6，我创建了一个新项目，并从之前使用过这个库的项目中复制了UIBubbleTable源代码，并且根据我上次的检查工作仍然正常。

旧项目适用于此库，但新项目会出错。

我添加了所有需求框架，但仍然是错误。

以下是我的错误日志，请帮忙。

看起来该库需要一个导入UIKit / UIKit.h的.pch文件（请参阅示例目录中的UIBubbleTableViewExample-Prefix.pch）。您可以向项目添加类似的pch文件。或者，您可以将以下内容添加到您看到这些错误的头文件中：

#import <UIKit/UIKit.h>
