Check Internet Connectivity Using AFNetworking 2.0

I have created NetworkRechabilityMonitor class to get the Internet Connection status in my app using AFNetworking 2.0 library.

1. Create an NSObject class naming NetworkRechabilityMonitor, add below code in respective Header & Implementation files.

  NetworkRechabilityMonitor.h

#import <Foundation/Foundation.h>

@interface NetworkRechabilityMonitor : NSObject

+(void)startNetworkReachabilityMonitoring;

+(BOOL)checkNetworkStatus;

@end

NetworkRechabilityMonitor.m

#import "NetworkRechabilityMonitor.h"

@implementation NetworkRechabilityMonitor

#pragma mark - Start Monitoring Network Manager

+(void)startNetworkReachabilityMonitoring {

    [[AFNetworkReachabilityManager sharedManager] startMonitoring];

}

#pragma mark - Check Internet Network Status

+(BOOL)checkNetworkStatus {

    return [AFNetworkReachabilityManager sharedManager].reachable;

}

@end

2. Import the NetworkRechabilityMonitor in your ViewController class where you want to check the internet status.

3. In viewDidLoad method of your ViewController add below line of code:

[NetworkRechabilityMonitor startNetworkReachabilityMonitoring];

4. Now in ViewController if i want to check internet status before making an API call add below code:

if ([NetworkRechabilityMonitor checkNetworkStatus]) {

          NSLog(@"Connected to Internet");

          // Add your code

} else {

         NSLog(@"Not Connected to Internet");

         // Notify user to connect to Internet

}
