reachability

1. NSUserDefaults 　　个人认为ios这个方法有点类似于 c#中Properties.Settings.Default ，NSUserDefaults只支持： NSString, NSNumber, NSDate, NSArray, NSDictionary. 　　创建一个user defaults方法有多个，最简单得快速创建方法: 　NSUserDefaults *accountDefaults = [NSUserDefaults standardUserDefaults]; 　　添加数据到 user defaults: 　　[accountDefaults setObject:nameField.text forKey:UserDefaultNameKey]; 　　也可以添加基本数据类型int, float, bool等，有相应得方法 　　[accountDefaults setBool:YES forKey:UserDefaultBoolKey]; 　　从user defaults中获取数据: 　　[accountDefaults objectForKey:NCUserDefaultNameKey] 　　[accountDefaults boolForKey: UserDefaultBoolKey]; 针对同一个关键字对应的对象或者数据，可以对它进行重写

I am creating a new Traveling Application in iOS, this application is highly dependent on Maps and will include two Maps. My first Map will work when the user has a strong Network Signal (Apple Maps). My second Map will be used when their isn't any Network or really Low signal (Offline MapBox). Why do I have two different maps in one Application? My Application is a Direction App, so when the user has really low network or none it will go to the offline Map MapBox . Also the Apple Maps will have Yelp integration and not the offline Map MapBox . So my Question: How can I detect the network

I'm trying to integrate network connectivity detection into my app, however it seems that somewhere along the line I have made a mistake as my network changes are not being detected/printed out into the console. As mentioned in the post, I'm currently using these following classes and tools for the job: Reachability {.h, .m} NSNotificationCenter Network Link Conditioner Code In the AppDelegate.Swift , I've set up the NSNotificationCenter to detect changes: func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // ... // A:

Has anyone found a halfway decent guide to implementing Reachability on iOS? enbr I have implemented Reachability like this. Download https://developer.apple.com/library/content/samplecode/Reachability/Introduction/Intro.html and add Reachability.h and .m to your project. Add the SystemConfiguration framework to your project. #import "Reachability.h" where you want to use it. Use this code. -(BOOL)reachable { Reachability *r = [Reachability reachabilityWithHostName:@"enbr.co.cc"]; NetworkStatus internetStatus = [r currentReachabilityStatus]; if(internetStatus == NotReachable) { return NO; }

I've found several examples of code to do what I want (check for reachability), but none of it seems to be exact enough to be of use to me. I can't figure out why this doesn't want to play nice. I have the reachability.h/m in my project, I'm doing #import <SystemConfiguration/SystemConfiguration.h> And I have the framework added. I also have: #import "Reachability.h" at the top of the .m in which I'm trying to use the reachability. Reachability* reachability = [Reachability sharedReachability]; [reachability setHostName:@"http://www.google.com"]; // set your host name here NetworkStatus
