两篇关于Reachability的使用方法
Reachability使用
how to use Reachability
上代码：
// 检查检查网络状态是否当前网络可用
func checkNetworkStates() {
// 初始化
self.reach = Reachability.reachabilityForInternetConnection()
self.reach?.reachableOnWWAN = false
// 添加通知
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(AppDelegate.reachabilityChanged(_:)), name: kReachabilityChangedNotification, object: nil)
self.reach!.startNotifier()
}
// 每次有网络切换的时候调用
func reachabilityChanged(noti:NSNotification) {
if self.reach!.isReachableViaWiFi() || self.reach!.isReachableViaWWAN() {
print("当前网络可用")
}else {
print("当前网络不可用")
// 网络不可用是添加 提示框
altertStatus()
}
}
// 无网络状态添加提示框
func altertStatus() {
let alerContl = UIAlertController.init(title: "斗笔提示您：", message: "无网络链接", preferredStyle: UIAlertControllerStyle.Alert)
let action1 = UIAlertAction.init(title: "取消", style: UIAlertActionStyle.Cancel, handler: nil)
let action2 = UIAlertAction.init(title: "设置", style: UIAlertActionStyle.Default) { (action) in
// 打开系统wifi 设置界面
let url = NSURL(string: "prefs:root=WIFI")
UIApplication.sharedApplication().openURL(url!)
}
alerContl.addAction(action1)
alerContl.addAction(action2)
self.window?.rootViewController?.presentViewController(alerContl, animated: true, completion: nil)
}```
如何打开系统的各种设置界面：
#####首先，进行设置info 的URL Types
```swift
let url = NSURL(string: "prefs:root=WIFI")
UIApplication.sharedApplication().openURL(url!)
所有设置对应的url：
