我正在尝试将 Facebook SDK 实现到我的项目中，但我遇到了同样的问题
Facebook sdk is not a dylib error after update update Xcode 7?
好吧，我的 Frameworks 目录中也有 Bolts
在我的build设置中:
Frameworks 搜索路径:~/Documents/Frameworks/FacebookSDKs-iOS-4.27.0
(这对我来说是正确的)
在我的 Briding-Header.h
#import <Bolts/Bolts.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
但是，我仍然遇到同样的错误，另外，我刚刚删除了Derived data。
错误是:
ld: warning: Auto-Linking supplied '/Users/jarvis/Documents/Frameworks/FacebookSDKs-iOS-4.27.0/FBSDKCoreKit.framework/FBSDKCoreKit', framework linker option at /Users/jarvis/Documents/Frameworks/FacebookSDKs-iOS-4.27.0/FBSDKCoreKit.framework/FBSDKCoreKit is not a dylib

Undefined symbols for architecture x86_64:

objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
有人知道这个错误吗？
最佳答案
嗯，这个解决方案很奇怪，基本上，我删除了拖放到我的 Framework 组，然后我添加了 FBSDKCoreKit、FBSDKLoginKit 和 Bolt 使用常规设置将它们添加到 Linked Frameworks and Libraries
关于ios - Xcode 9 _OBJC_CLASS_$_FBSDKApplicationDelegate，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46454468/
