objective-c – 使用SDWebImage时构建失败

概述我试图在我的项目中使用 SDWebImage的类. 我已经将类添加到我的项目中,当我尝试构建它时,我会收到7个错误： Undefined symbols for architecture i386: "_OBJC_CLASS_$_MKAnnotationView", referenced from: l_OBJC_$_CATEGORY_MKAnnotationView_$_WebC 我试图在我的项目中使用 SDWebImage的类.

我已经将类添加到我的项目中,当我尝试构建它时,我会收到7个错误：

我是XCode和Objective-c的新手,所以我不知道这个错误是什么意思.

任何人？

谢谢.

解决方法 看来你需要将MapKit和ImageIO添加到项目中.

要做到这一点：

>点击Xcode中项目导航器顶部的项目.>选择“构建阶段”选项卡.>打开“使用库链接二进制”框.>点击”.> AppMapKit和ImageIO框架.
