Answer 1

您的Youtube_SearchViewController.m和其他Youtube_SearchView.m文件在您的「編譯源」構建階段中列出兩次。

在左側的Project Navigator中選擇您的項目，然後在目標列表中選擇您的目標，轉到「構建階段」選項卡，並刪除每個重複的文件（以便每個.m文件僅列出一次）。如何解釋生成日誌

詳細（加着重號並重新格式化）：

duplicate symbol _OBJC_IVAR_$_Google_SearchView.refParentViewController in:

• /Users/alyjamy/Library/Developer/Xcode/DerivedData/SearchPRO-byuygadvkgrdzqgiethjtvoscvzp/Build/Intermediates/SearchPRO.build/Debug-iphonesimulator/SearchPRO.build/Objects-normal/i386/Google_SearchView-F440D65BB38D9558.o

在上面的提取物中，Google_searchView.m編譯兩次，同時生產Google_SearchView-F440D65BB38D9558.o和Google_SearchView-41A2B8A23D2A1652.o
