IOS Monitoring Network changes

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 transformation , so using the reachability in this example . (h/m) file in its own project is premised on the need to introduce systemconfiguration.framework.

Import header file:

#import "NetworkReachability.h"

Defining Global Variables

Networkreachability *_netreachability;

Initialize a variable and assign a value to the agent

    _netreachability = [[Networkreachability alloc] init];    _netreachability.delegate = self;

Implementation of the Agent

#pragma mark-networkreachability delegate-(void) reachable: (NetworkStatus) netstatus {    switch (netstatus) {        Case notreachable:            NSLog (@ "No network!");            break;        Case Reachableviawifi:            NSLog (@ "WiFi");            break;        Case Reachableviawwan:            NSLog (@ "3G");            break;        Default: Break            ;    }}

Of course, don't forget the proxy statement:

<NetworkReachabilityDelegate>

over!
