https使用相关资料

首先  从服务器开发人那拿到crt证书  然后点击装在钥匙串里  然后右键导出成cer 然后把这个cer放到你的工程目录 这样AFN就会自己找到 然后在请求的时候  给op  或是  manager写上那几句就行了  AFHTTPRequestOperation
*op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    AFSecurityPolicy *policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
    //是否允许CA不信任的证书通过
    policy.allowInvalidCertificates = YES;
    //是否验证主机名
    policy.validatesDomainName = NO;

    op.securityPolicy = policy;
