iOS开发之用RealReachability监控网络状态检测网络状态

1.cocoapods导入RealReachability

2.使用
oc需要的文件中导入

#import  

swift需要的地方导入

import RealReachability

3.打开监控

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
   [[RealReachability sharedInstance] startNotifier];
   return YES;
}

4.在当前页面添加观察者

//在具体的页面添加观察者(实时监测网络的变化)

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(netWorkstate:) name:kRealReachabilityChangedNotification object:nil];
}

//观察者实时检测方法
- (void)netWorkstate:(NSNotification *)notice {
    RealReachability *reachability =  (RealReachability *)notice.object;
    
    //检测网络
    NSInteger status = [reachability currentReachabilityStatus];
    [self notNetPrompt:status];
}

5.每次进当前页面都检测下网络状态

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    
    //检测网络
    NSInteger status = [[RealReachability sharedInstance] currentReachabilityStatus];
    [self notNetPrompt:status];
}
