在SDWebImageDownloader中找不到架构i386的符号

Question

当我试图用Xcode编译时,我得到以下错误:

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:
      -[SDWebImageDownloader connection:didReceiveData:] in SDWebImageDownloader.o
  "_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)

必须存在SDWebImage类的问题,MWPhotoBrowser使用该类.这真的很奇怪和令人困惑,我不知道如何解决它.

多谢你们.
