我完全不敢尝试使用AFNetworking在模拟器上运行项目.我之前在其他项目上使用过这种依赖,所以我不明白这里出了什么问题.首先,我尝试运行项目时出错:

Undefined symbols for architecture x86_64:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

我确信这是问题的一部分,但我不知道如何解决它:

#import <AFNetworking/AFNetworking.h>
#import "SharedSessionKey.h"

@interface SharedNetworkObject : AFHTTPSessionManager

@end

值得注意的是,当我开始输入AFNetworking的导入行时,该行会在几个字符后填写,所以我知道有一些AFNetworking依赖存在的意识.

我使用CocoaPods安装了依赖项.这是我的Podfile:
