实时网络监测问题

有点问题,我的数据加载是在

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions
  方法中,然后代码是这样子,按我的理解你的代码应该是实时监测网络,不管在任何界面,只要由无网络状态切换到有网,数据就应该开始加载了...

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
   {
  [GLobalRealReachability startNotifier];
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkChanged:) name:kRealReachabilityChangedNotification object:nil];
  // 所有数据更新
   [[NDNewsData sharedData] updateAd];
    // 应用信息更新
    [[NDNewsData sharedData] updateApp];
    // 栏目数据更新
    [[NDNewsData sharedData] updateSource];
    
       return YES;
     }
  

  • (void)networkChanged:(NSNotification *)notification{
    RealReachability * reachability = (RealReachability *)notification.object;
    ReachabilityStatus status = [reachability currentReachabilityStatus];
    if (status != RealStatusNotReachable)
    {
    // 所有数据更新
    [[NDNewsData sharedData] updateAd];

    [[NDNewsData sharedData] updateApp];

    [[NDNewsData sharedData] updateSource];

  }

  • (void)dealloc{
    [[NSNotificationCenter defaultCenter]removeObserver:self name:kRealReachabilityChangedNotification object:nil];
    }

这样写有什么毛病吗?为什么我无网状态下启动app,之后再打开网络还是没有加载呢?
