当我尝试使用 Xcode 编译时，出现以下错误：

Undefined symbols for architecture i386:
  "_CGImageSourceCopyPropertiesAtIndex", referenced from:
      -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownloader.o
  "_CGImageSourceCreateImageAtIndex", referenced from:
      -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownloader.o
  "_CGImageSourceCreateIncremental", referenced from:
      -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownloader.o
  "_CGImageSourceUpdateData", referenced from:

  "_OBJC_CLASS_$_MFMailComposeViewController", referenced from:
      objc-class-ref in MWPhotoBrowser.o
  "_kCGImagePropertyPixelHeight", referenced from:
      -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownloader.o
  "_kCGImagePropertyPixelWidth", referenced from:
      -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownloader.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

MWPhotoBrowser 使用的 SDWebImage 类一定有问题。这真的很奇怪和令人困惑，我不知道如何解决它。

多谢你们。

问题很可能是该项目不包含 ImageIO 框架。转到您的 Target -> Build Phases -> Link 并验证实际上您在那里有 ImageIO。

我认为我有解决方案...

转到您的应用程序的目标，然后在右侧，单击Build Phases选项卡，然后在Compile Sources部分中单击+并添加SDWebImage.m

希望有帮助！
