使用多個框架會產生clang：錯誤：鏈接器命令失敗，退出代碼為1

Question

就像我說的..我正在使用兩個框架，FlashIz和MWPhotoBrowser。 （實際上，我使用的更多，但它們不會出錯。）

在構建項目時，出現如下錯誤：

ld: 29 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

因此，我從這個錯誤中得出了那兩個框架正在使用相同的“框架”（例如MBProgressHUD）的信息。 所以我想刪除其中之一？ 但是我不知道怎么辦。有人嗎？ 問題是，我似乎找不到此文件？

Answer 1

這里的問題是重復 。 MBProgressHUD已添加兩次（來自libMWPhotoBrowser.a和FlashizEmbeddedLibrary ）

因此，從任何一個庫中刪除。

Answer 2

它表明這是由於重復的符號。 在您的項目中，有MBProgressHUD多個類。 請僅使用一個類，並刪除其他類。 這樣可以解決您的問題，
