IJReachability是一个使用Swift写的第三方网络检测类。可以测试网络是否连接，并支持3G和Wifi的检测。

使用样例：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

import UIKit   class ViewController: UIViewController {           @IBOutlet weak var statusLabel: UILabel!        @IBOutlet weak var typeLabel: UILabel!              override func viewDidLoad() {         super.viewDidLoad()     }              @IBAction func checkConnect(sender: AnyObject) {         //判断连接状态         if IJReachability.isConnectedToNetwork(){             statusLabel.text = "网络连接：可用"         }else{             statusLabel.text = "网络连接：不可用"         }                   //判断连接类型         let statusType = IJReachability.isConnectedToNetworkOfType()         switch statusType{             case .WWAN:                 typeLabel.text = "连接类型：移动网络"             case .WiFi:                 typeLabel.text = "连接类型：WiFi"             case .NotConnected:                 typeLabel.text = "连接类型：没有网络连接"         }     }           override func didReceiveMemoryWarning() {         super.didReceiveMemoryWarning()     } }
