####We need to observe the REAL reachability of network for iOS. That's what RealReachability do.
#Why RealReachability?
As we know, we already have reachability framework for us to choose. Such as the famous repository Reachability.
BUT we really need a tool for us to get the reachability, not the local connection!
Apple doc tells us something about SCNetworkReachability API: "Note that reachability does not guarantee that the data packet will actually be received by the host."
The called "reachability" we already know can only tell us the local connection status.These tools current we know are all supported by the SCNetworkReachability API.
Now RealReachability can do this for you~
We introduce ping module for us to check the real network status, together with SCNetworkReachability API. And we use FSM(finite state machine) to control all of the network status to confirm that only status change will be sent to application.
Enjoy it!
#Quick Start With Cocoapods CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like RealReachability in your projects. You can install it with the following command:
$ gem install cocoapods
To integrate RealReachability into your Xcode project using CocoaPods, specify it in your Podfile
:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '6.0'
pod 'RealReachability', '~> 1.1.1'
Then, run the following command:
$ pod install
#Manual Start If you'd rather do everything by hand, just add the folder "RealReachability" to your project, then all of the files will be added to your project.
- Xcode 5.0+ for ARC support, automatic synthesis and compatibility libraries. iOS 6.0+.
- The SystemConfiguration Framework should be added to your project.
#Usage ####Start to notify:
[GLobalRealReachability startNotifier];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(networkChanged:)
name:kRealReachabilityChangedNotification
object:nil];
####Observer like below:
- (void)networkChanged:(NSNotification *)notification
{
RealReachability *reachability = (RealReachability *)notification.object;
ReachabilityStatus status = [reachability currentReachabilityStatus];
NSLog(@"currentStatus:%@",@(status));
}
####Trigger realtime Reachability like below:
[GLobalRealReachability reachabilityWithBlock:^(ReachabilityStatus status) {
switch (status)
{
case RealStatusNotReachable:
{
// case NotReachable handler
break;
}
case RealStatusViaWiFi:
{
// case WiFi handler
break;
}
case RealStatusViaWWAN:
{
// case WWAN handler
break;
}
default:
break;
}
}];
ReachabilityStatus status = [reachability currentReachabilityStatus];
Once the reachabilityWithBlock was called, the "currentReachabilityStatus" will be refreshed synchronously.
Please make sure the host you set here is available for pinging. Large, stable website suggested.
This step is optional. If you do not set this, our default host is: www.baidu.com.
You may set your own host any time you like. Codes just like below:
GLobalRealReachability.hostForPing = @"www.baidu.com";
#Demo We already put the demo project in the repository.

Please use and improve! Patches accepted, or create an issue.
I'd love it if you could send me a note as to which app you're using it with! Thank you!
