Check if your iOS device’s internet connection is working properly.

Question

There are many questions about finding an active Internet connection in the application, but no one works if you use a 3g connection and you do not have access to data, or if you are on a WiFi network in a hotel, which is automatically redirected to the login page, and you are not yet entering a password. Such situation.

What is the fastest way to check if your internet connection is working?

Answer 1

You can use the AFNetworkReachabilityManager class in AFNetworking .

https://github.com/AFNetworking/AFNetworking

. . :

[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
}];

[[AFNetworkReachabilityManager sharedManager] startMonitoring];

Answer 2

, Reachability API, - NSURL . - 20 .

- (void)checkConnection //Run this on a side queue, never on a main queue
{    NSURL *checkURL = [NSURL URLWithString:@"http://www.apple.com"];

    NSURLRequest *lRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:checkURL]
                                              cachePolicy:NSURLRequestUseProtocolCachePolicy
                                          timeoutInterval:20.0];

    NSData *data = [NSData dataWithContentsOfURL:lRequest];

    if (data)
    {
        connected = YES;
    }
    else
    {
        connected = NO;
    }
}
