如何在Socket编程中传递SSL安全证书

Question

我在iOS的Socket Communication工作。下面是我所做的代码。

let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .PhotoLibrary
picker.allowsEditing = true

let camera = UIBarButtonItem(barButtonSystemItem: .Camera, target: picker, action: Selector("btnOpenCamera"))
picker.navigationItem.leftBarButtonItem = camera

presentViewController(picker, animated: true, completion: nil)

但我无法启动连接。问题是主机是否使用SSL证书启用。我的服务器团队说我已经使用证书连接到主机。他们已经颁发了证书。这是＆＃34; digicert.crt＆＃34;

请帮助我使用证书连接主机。
