问题描述

swift 环形进度条，显示不出来

  func onClickConfirm()        {        ///check if ipusernamepassname is correct           println(m_ServerAddress.text)            //eares the space before and after            // let REMOTE_SYNC_SERVER_URL: String = ""http:/"" + m_ServerAddress.text + ""/spssmr/mobilesync""            //println(REMOTE_SYNC_SERVER_URL)                        //self.presentViewController(process animated: true completion: nil)            //m_connect?.logonServer(REMOTE_SYNC_SERVER_URL m_Username.text m_Password.text)            var myActivityIndicator : UIActivityIndicatorView = UIActivityIndicatorView()            myActivityIndicator.center = self.view.center            myActivityIndicator.hidesWhenStopped = true            myActivityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray            view.addSubview(myActivityIndicator)            myActivityIndicator.startAnimating();           myActivityIndicator.hidden = false            m_connect?.logonServer(""http://192.168.56.101/spssmr/mobilesync""admin""1"")            sleep(10)            m_connect?.getDCProjects(""http://192.168.56.101/spssmr/mobilesync"")            myActivityIndicator.stopAnimating()        }

解决方案

找到原因了：代理没有设置

lazy var tableView :UITableView? = {        let view = UITableView(frame: self.view.framestyle: UITableViewStyle.Plain)        view.dataSource = self        view.delegate = self        return view    }()
