reachability

问题 I have Reachability working exactly as suggested as in this thread. I am using the open source Reachability. However I am not using blocks but notifications, hence the process is pretty similar to the Apple's Reachability code. The first time I start the app, I run this and it works great. Reachability *reachability = [reach hostReachability]; [reachability startNotifier]; The reachabilityChanged: event is firing: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector

问题 I am facing weird problem on iPhone 5 with iOS 7, i have tested same code with other devices like iPad1, 2, 3 and iPhone 4, 4s etc. with different iOS combination including iOS 7. Problem : When i turn on airplane mode i do get reachability notification as expected with status NotReachable but immediately after that app receives notification with status code ReachableViaWWAN which is not expected. Code : +(BOOL)checkReachability { Reachability* internetReachable = [Reachability

问题 Downloaded Reachability from Apple, using this method to check for an active connection: -(BOOL)isReachable{ Reachability *r = [Reachability reachabilityWithHostName:@"http://www.google.com"]; if(NotReachable == [r currentReachabilityStatus]) { NSLog(@"Not Reachable"); return NO; } NSLog(@"Reachable"); return YES; } Returns NO every single time despite being connected? Can't figure out why... Any ideas? Thanks. On a side note, can anyone recommend a good clean Reachability singleton class?

问题 When my app launches, I check for reachability because I need an immediate internet connection. My problem, though, is that it appears there's no immediate confirmation for the NetworkStatus , which means right after the Reachability is setup, I check whether there's a connection, and it returns that there isn't, regardless of whether I am in fact on WiFi/3G, or have turned the radio off. I can confirm that I am in fact getting an Internet connection, because instantly after

问题 I have client server say "http://abc.com" and i want to check whether this server responding or not. How to check this with Reachability code from apple? As i see that code but not able to get where to write my client's url to check this. Please suggest me. 回答1: Here's a synchronous example. You'll probably want to do this asynchronously, but this will get you through for a quick check. Reachability *netReach = [Reachability reachabilityWithHostName:@"host.name"]; //return [netReach

问题 I am trying hard to get the authentic internet connectivity status. I have used Apple's Reachability but it's only giving me the status of wifi connectivity i.e. not covering the case when the device is connected via wifi (to a router or hotspot), but the wifi router or hotspot itself is not connected to the internet. This scenario is reproducible by pulling the internet input cable from wifi router. The reachability's notifier returns ReachableViaWiFi for both

问题 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

问题 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...

问题 This question already has answers here : How to check for an active Internet connection on iOS or macOS? (42 answers) Closed 2 years ago . how I can check quickly if the iPhone is connected to internet or not, quickly... Thanks... 回答1: Have a look at Apple's Reachability class and this example app. 回答2: You should try to connect to the server with what you think is an appropriate timeout. NEVER use the reachability API until you've determined that your connection attempt failed and even then
