reachability

Using Apple's Reachability code in iOS5 I get a bunch of compilation errors as shown below. Any ideas on what is happening here? I'm using ARC so I have edited the standard code slightly to remove autorelease/retain and the NSAutoReleasePool . Undefined symbols for architecture armv7: "_SCNetworkReachabilityCreateWithAddress", referenced from: +[Reachability reachabilityWithAddress:] in Reachability.o "_SCNetworkReachabilityCreateWithName", referenced from: +[Reachability reachabilityWithHostName:] in Reachability.o "_SCNetworkReachabilityUnscheduleFromRunLoop", referenced from: -[Reachability

Currently i am using the class by apple reachability.m/.h and it works, except it notifies me for any change, where as i would like to only notify the user if the network is not reachable. Currently if i have a internet connection and then loose the network it tells me. However when you reconnect to the network it also tells me, which i do not want. I want it to only tell me when there is a loss/no network. I believe it has something to do with the call: - (void)viewWillAppear:(BOOL)animated { // check for internet connection [[NSNotificationCenter defaultCenter] addObserver:self selector:

I found a reachibility code online, unfortunately it only works for the wifi Network. I Need a code to determine if a person has an internet connection: this includes wifi and data. Any help is greatly appreciated! You can use the Reachability framework. Install it through CocoaPods with pod 'ReachabilitySwift', '~> 3' . To use it: Declare a global variable: var reachability = Reachability()! Add an observer and start the notifier in your viewWillAppear : override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(true) NotificationCenter.default.addObserver(self, selector: #selector

I want to be able to check for internet connectivity when my View loads. To predetermine the contents of my view. I have the following viewDidLoad method: - (void)viewDidLoad { [super viewDidLoad]; if(![self hasInternetConnection]){ NSLog(@"SHOW ORIGINAL DOC"); } else{ NSLog(@"SHOW NEW DOC"); } } And I have a method called hasInternetConnection as follows: - (BOOL)hasInternetConnection{ NSLog(@"Starting connection test"); internetReachableFoo = [Reachability reachabilityWithHostname:@"www.google.com"]; // Internet is reachable internetReachableFoo.reachableBlock = ^(Reachability*reach){ //

I want to check a server is live or not with ip, for example, 74.125.71.104 (Google's ip) // allocate a reachability object `struct sockaddr_in address; address.sin_len = sizeof(address); address.sin_family = AF_INET; address.sin_port = htons(80); address.sin_addr.s_addr = inet_addr("74.125.71.104");` Reachability *reach = [Reachability reachabilityWithAddress:&address]; but those not working. When I change to reachabilityWithHostname , it's working. Please import #include <arpa/inet.h> [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name

I want to do some tasks as soon as user comes online even he is in background. I am using Reachability class for checking internet. But this class is not notifying me when i am at background. I know people asked this question earlier but didn't got any solutions there. If i use beginBackgroundTaskWithExpirationHandler . It gives me 3 to 4 min only, after that if network change i am not getting any notification. Please suggest me something.I think it is possible because native mail app work in that manner and my app support iOS7 only. You cannot get notification form your classes while the app

I just need to check the internet connection availability before start communicating with the service in my iphone App. I am using Swift 1.2 and Xcode 6 as my development environment... I've just done some research and found this stackoverflow LINK in objective C. Therefore I just tried to find a similar solution in SWIFT and found the following link https://coderwall.com/p/mhxbpq/checking-for-internet-connection-availability Just to make things easy the content in that link is as follows... import Foundation import SystemConfiguration public class Reachability { class func
