GCDAsyncSocket 監聽綁定

NSError *error = nil;
[self.server acceptOnPort:self.portNumber.intValue error:&error];
if (error) {
  NSLog(@"%@", error);
}

報錯

mac Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedDescription=Operation not permitted, NSLocalizedFailureReason=Error in bind() function}

終端監聽 端口12345 Connection refused

~ telnet 127.0.0.1 12345
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host

最佳答案

生成的Xcode授權阻止了綁定
MacService.entitlements 將這些值改為false現在綁定工作
