体系结构"_OBJC_CLASS _ $ _ AFHTTPClient"的未定义符号； [英] Undefined symbol for architecture "_OBJC_CLASS_$_AFHTTPClient"

问题描述

Iam与AFNetwork一起使用cocoapods.当我编译followig错误时出现:

Iam using cocoapods with AFNetwork. When I compile the followig error appears:

Undefined symbols for architecture i386:

  "_OBJC_CLASS_$_AFHTTPClient", referenced from:

对于cocoapod类，无论是64位还是32位，都会发生这种情况.尝试过的解决方法是:

It happens for the cocoapod classes either with 64 bits or 32. Tried solutions from here:

AFNetworking库在iOS 7中失败

在这里:

架构arm64的未定义符号

但是他们不起作用，我错过了什么吗?

but they don't work, am I missing something?

我包含了该项目，但是是否必须以其他方式链接它?

I included the project, but do I have to link it in some other way?

推荐答案

出现此问题是因为JSONKIT的源文件存在弃用的语法问题，自动修复显然阻止了该类的访问，如此处所述 https://stackoverflow.com/a/14191829/2394901 .这是因为pod文件指定:

The problem arises because there is a syntax issue with a deprecation on the source files of JSONKIT, the auto fix apparently prevents the class from being accessed as mentioned here https://stackoverflow.com/a/14191829/2394901. This is in turn is because the pod file specifies:

pod 'AFNetworking', '~> 1.2'

我移除了Pod(请参阅如何从项目中移除CocoaPods?)，然后重新安装:

I removed the pod (see How to remove CocoaPods from a project?) and then reinstalled:

$ pod install

使用:

pod "AFNetworking", "~> 2.0"
