startMonitoringSignificantLocationChanges可以終止我的應用程序

Question

我是想在我的應用程序使用startMonitoringSignificantLocationChanges，但我有一些問題，我希望得到一些幫助：

1. 爲了一個共同的應用，如果應用程序進入的背景下，10分鐘後，系統可以殺死app.if我使用startMonitoringSignificantLocationChanges，當我進入後臺兩個小時後，我的應用程序沒有終止，因爲我點擊圖標，應用程序將進入最後一個退出頁面。如果應用程序被殺死，當你點擊圖標時，你會首先看到默認頁面。所以我的問題是使用startMonitoringSignificantLocationChanges我的應用程序沒有被系統殺死後輸入背景10分鐘？

2. 如果我關閉手機，並重新啓動手機，當顯著位置的變化，我的應用程序是否可以激活，我期待的蘋果開發文檔就回答yes.so我測試：

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  
   
   
   if([CLLocationManager significantLocationChangeMonitoringAvailable]){ 
   [self log:@"sigAvailable=YES"]; 
   } 
   // Override point for customizatio-n after application launch. 
   
   id locationValue = [launchOptions objectForKey:UIApplicationLaunchOptionsLocationKey]; 
   
   if (locationValue) 
   { 
   // create a new manager and start checking for sig changes 
   [self log:@"didFinishLaunchingWithOptions location key"]; 
   m_locManager = [[CLLocationManager alloc] init]; 
   [self log:@"didFinishLaunchingWithOptions created manager"]; 
   m_locManager.delegate = self; 
   [self log:@"didFinishLaunchingWithOptions set delegate"]; 
   [m_locManager startMonitoringSignificantLocationChanges]; 
   [self log:@"didFinishLaunchingWithOptions monitoring sig changes"]; 
        // do send local notification 
   return YES; 
       } 
   
   [self log:@"didFinishLaunchingWithOptions"]; 
   return YES; 
       } 
   

   我的問題：當重新啓動手機和本地通知，上面的代碼運行並記錄「didFinishLaunchingWithOptions位置鍵」等，如果我發送上述代碼的本地通知，如果用戶將收到？

Answer 1

1. 在iOS 6中有對地圖的新功能，停止位置更新 它有助於喚醒應用收到位置更新。 link

   locationManager.pausesLocationUpdatesAutomatically

另見all others。

1. 您的應用可以在設備啓動時啓動，如果它的VOIP。 看到這個apple doc

本地通知加入

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 




// creating local notification 
    Class cls = NSClassFromString(@"UILocalNotification"); 
    if (cls) 
    { 
     UILocalNotification *notification = [launchOptions objectForKey: 
              UIApplicationLaunchOptionsLocalNotificationKey]; 

     if (notification) 
     { 
      NSString *reminderText = [notification.userInfo 
             objectForKey:kRemindMeNotificationDataKey]; 
      NSLog(@"notification text:%@",reminderText); 
      // [viewController._msgTextView setText:reminderText]; 
     } 
    } 

    application.applicationIconBadgeNumber = 0; 

，您可以在

- (void)application:(UIApplication *)application 
didReceiveLocalNotification:(UILocalNotification *)notification 
{ 
    NSLog(@"application:didReceiveLocalNotification:"); 
} 

處理它們，你可以安排本地通知在

-(void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 
{ 

Class cls = NSClassFromString(@"UILocalNotification"); 
      if (cls != nil) 
      { 
       UILocalNotification *notif = [[cls alloc] init]; 
       notif.fireDate = notifyDate; 
       notif.timeZone = [NSTimeZone defaultTimeZone]; 
       notif.alertBody = AlertMsg; 
       notif.soundName = UILocalNotificationDefaultSoundName; 
       notif.applicationIconBadgeNumber = [[UIApplication sharedApplication]applicationIconBadgeNumber]+1; 
       notif.alertAction = @"Show me"; 
       [[UIApplication sharedApplication] scheduleLocalNotification:notif]; 
} 
}
