iOS error：framework not found Bolts for architecture arm64

ld: framework not found Bolts for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

处理方法：

把facebook的framework从文件中移除，改用cocoapod来到入facebook的 sdk

先pod search 一下facebook的sdk，然后复制粘贴你需要的到pod file里面

pod 'FBSDKLoginKit', '~> 4.16.1'
pod 'FBSDKCoreKit', '~> 4.16.0'
pod 'FBSDKShareKit', '~> 4.16.1'
