ios – 在SDWebImageDownloader中找不到体系结构i386的符号

概述当我试图使用Xcode编译时，我会收到以下错误： Undefined symbols for architecture i386: "_CGImageSourceCopyPropertiesAtIndex", referenced from: -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownlo 当我试图使用Xcode编译时，我会收到以下错误：

SDWebImage类必须有一个问题，MWPhotobrowser使用这个类。
这真的很奇怪，令人困惑，我不知道如何解决它。

多谢你们。
