Ios5 无法链接到库

我正在努力在代码中链接库

我已经在谷歌上搜索了很多关于这一点的内容，并遵循了不止一个教程直到最后一点，但我仍然是我开始的地方

您需要将

assetsbrary

框架添加到

picktumb

目标的“使用库链接二进制文件”构建阶段

---

在我刚刚添加的Xcode 10.2中

AssetsLibrary.framework

---

在目标>构建阶段>将二进制文件链接到库部分

添加后，我收到以下错误：

ld:警告：忽略文件/Users/vedprakash/Documents/XCode Projects/picktumb/AssetsLibrary.framework/AssetsLibrary，该文件是为不受支持的文件格式构建的，而不是所链接的体系结构（i386）

这不是

资产库

框架的正确位置。我认为您没有按照链接中的说明进行操作。我已经添加了链接中的框架，并且库显示在“使用库链接二进制文件”下的列表中。如果添加正确，link命令应显示为

-framework AssetsLibrary

。它不应该有一个以

/AssetsLibrary

结尾的路径。谢谢Rob:）。我删除并添加了库，并成功构建了它。
