iOS Development--Network Programming OC Chapter & (v) Network monitoring

With the mobile network upgrade: 2G->3G->4G even the development of 5G, the network speed is more and more fast, but this flow is like flowing water generally rushing away.

Online is not a joke: sleep forgot to close the flow, the next day the house will be moved!

This is an exaggeration to say, but as a good app developer, we need to give the most appropriate hints in the app.

Give some hints when you need to spend a lot of traffic (for example: video, downloads, etc.).

When users switch the network during user video, give the prompt to continue watching!

The following author gives a real-time monitoring of the network status change Method!

I use the network to spread the widest network monitoring class: Reachability

Unzip the files downloaded above and add the Networkreachability folder to the project you need to add.

Example Description: This example demonstrates how to use the Systemconfiguratio Reachalility program interface to determine the associated network connection status and state changes, so use the reachability in this example. (h/m) file in its own project is premised on the need to introduce systemconfiguration.framework.

One: How to use reachability

 1-(void) Viewdidload 2 {3 [Super Viewdidload]; 4 5//monitor network status change Notification 6 [[Nsnotificationcenter Defaultce Nter] addobserver:self selector: @selector (networkstatechange) name:kreachabilitychangednotification Object:nil]; 7 8//Get Reachability object 9 self.reachability = [reachability reachabilityforinternetconnection];10//Start monitoring Network one by one [self.reachability startnotifier];12 13////1. Get Reachability object//reachability *wifi = [reachability re ACHABILITYFORLOCALWIFI];15//16////2. Gets the current network status of the Reachability object.//NetworkStatus Wifistatus = WIFI.CURRENTREAC HABILITYSTATUS;18/if (wifistatus! = notreachable) {//NSLog (@ "WiFi");//}21}22-(void) dealloc2 4 {self.reachability stopnotifier];26 [[Nsnotificationcenter Defaultcenter] removeobserver:self];27}28 29-( void) NetworkStateChange30 {NSLog (@ "network status changed"); [Self checknetworkstate];33}34-(void) Touchesbegan: (Nsset *) touches withevent: (uievent *) EVent36 {PNs [self checknetworkstate];38}39 40/**41 * Monitor network status */43-(void) checkNetworkState44 {if ([icocosn Etworktool Isenablewifi]) {NSLog (@ "Wi-Fi Environment"); (+) else if ([Icocosnetworktool isenable3g]) {NSLog (@ "Mobile phone comes with network"); NSLog} else {(@ "no network"); 51}52}

Judge

1//whether WIFI2 + (BOOL) Isenablewifi {3     return ([[[Reachability Reachabilityforlocalwifi] currentreachabilitystatus]! = notreachable); 4}5 6//whether 3g7 + (BOOL) isenable3g {8     return ([[Reachability reachabilityforinternetconnection] Currentreachabilitystatus]! = notreachable); 9}

Second: The use of AFN: (AFN is actually using the system from the reachability to achieve)
