ios - 使用自述文件中的示例时出现 AFNetworking 异常
<p><p>我还提交了一个问题 <a href="https://github.com/AFNetworking/AFNetworking/issues/1383" rel="noreferrer noopener nofollow">here</a> . </p>
<p>使用自述文件中的代码:</p>
<pre><code>AFHTTPRequestOperationManager *manager = ;
[manager GET:@"http://www.google.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
</code></pre>
<p>抛出以下异常:</p>
<pre><code>2013-09-27 22:16:10.345 Grades -: unrecognized selector sent to instance 0x1666c3f0
2013-09-27 22:16:10.349 Grades *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-: unrecognized selector sent to instance 0x1666c3f0'

</code></pre>
<p>我已确认所有 AFNetworking 文件都已更新到 2.0。</p>
<p>如何解决此异常？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>问题是某些文件没有正确更新。尝试从项目目录中删除所有 AFNetworking 文件，清理并构建，安装新文件，然后再次清理并构建。</p></p>
