objective-c - 需要帮助解决基本的 Objective-C 构建错误

Question

我对 objective-c 完全没有经验，现在才开始。和我一起工作的一个开发人员出国几天，不小心在代码中留下了一个错误，现在我无法编译一个Iphone应用程序来完成...

我通过邮件从他那里得到了一些信息，他告诉我他留下了一个名为 dialog 的库，我需要将其删除才能使其正常工作...

问题是我没有 objective-c 和 Xcode 的经验...我是网络开发人员 :)

我尝试运行该项目，但出现此错误:

Build target mormar

谷歌搜索了一段时间后，我仍然不知道如何解决这个问题......我将不胜感激任何帮助，谢谢!

您需要链接到 QuartzCore。

在 Xcode 边栏中单击您的项目名称。然后单击您的目标，并在“摘要”选项卡中找到链接框架和库的列表。单击此列表下方的加号按钮，然后添加 QuartzCore。
