问题
打包时，run debug没有问题，但是archive后export会发生错误，无法进入到选择证书的环节。
出现问题的提示框
log如下：

原因
可以看到，大体意思是说，打包时引用的一个framework文件，缺少了个资源叫"archived-expanded-entitlements.xcent"，网上查了一下资料好多都说是xcode6之后生成的。唉，这种回答都不靠谱，没有追根究底啊，有谁知道求教~
旧的framework
新的framework
对比了一下新旧版本的framework库内容，发现RSKImageCropper.framework旧版多了个_CodeSignature目录，大概是放签名文件的，还有就是一些头文件和资源的改动。怀疑可能是由于签名不正确或者其他原因所致。
解决
我去找了个新版的framework库，更新了一下，就一切正常了。
