请问能否提供利用GCDAsyncSocket 建立https的长连接的相关code，多谢~

[FrankCYQ]

-(void)socket:(GCDAsyncSocket *)socket didConnectToHost:(NSString *)host port:(uint16_t)port{

NSMutableDictionary *settings = [[NSMutableDictionary alloc] init];

[settings setObject:[NSNumber numberWithBool:YES]
             forKey:GCDAsyncSocketManuallyEvaluateTrust];


[self.socket startTLS:settings];

}

在原有基础上增加上面代码，还是无法正常访问https server，

• (void)socket:(GCDAsyncSocket *)sock didReceiveTrust:(SecTrustRef)trust completionHandler:(void (^)(BOOL))completionHandler
  这个回调方法不执行···
  多谢
