升级了XCode 8.1 ，之前一直用真机调试，程序没问题。后来改用模拟器调试，就出现了如下的错误：
CodeSign ~/Library/Developer/Xcode/DerivedData/...BundleName.bundle
cd ~/.../Pods
export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate
export PATH="..."
Signing Identity:"-"
/usr/bin/codesign --force --sign - --timestamp=none ~/Library/Developer/Xcode/DerivedData/...BundleName.bundle
~/Library/Developer/Xcode/DerivedData/...BundleName.bundle: bundle format unrecognized, invalid, or unsuitable
Command /usr/bin/codesign failed with exit code1
后来，到Stackoverflow去查找，还真是找到了，把地址贴上。
里面的方法如下：
Select Podsinthe navigation -->TARGETS -->your FDTakeResources -->Signing(Enable Development Signing) -->Identity(Choose Info.plist File).
同时还要注意，在Identity里面，需要选择info.plist文件，不过点击的时候，会弹出下拉框，选择就可以了。
