你能帮我做点什么吗

在编译源代码构建阶段，您的Youtube\u SearchViewController.m和其他Youtube\u SearchView.m文件将列出两次

在左侧的项目导航器中选择您的项目，然后在目标列表中选择您的目标，转到“构建阶段”选项卡，删除每个重复文件，以便每个.m文件只列出一次

在上面的摘录中，Google_searchView.m被编译了两次，生成了Google_searchView-F440D65BB38D9558.o和Google_searchView-41A2B8A23D2A1652.o

你能发布你的代码吗？发生错误的地方只是粘贴错误代码…..删除它们很酷现在有其他错误要编辑主题现在你仍然有重复的主函数，可能main.m文件仍然存在两次，或者在代码中两个不同的地方定义的主函数可能是非常感谢，在我解决它之后，我面临着我将要写的东西，那么也许你可以投票/接受我给你的解决方案？！
