推送通知的後臺處理

Question

當iPhone應用程序完全關閉時，即使不在後臺，也可以如何處理APNS處理。 例如應用程序完全關閉時，將APNS數據存儲在sqlite中。

Answer 1

中的AppDelegate：

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

    if (launchOptions) 
    { //launchOptions is not nil 

     NSDictionary *userInfo = [launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
     NSDictionary *apsInfo = [userInfo objectForKey:@"aps"]; 
     userInfoDic = userInfo; 

     if (apsInfo) 
     { //apsInfo is not nil 
      [self performSelector:@selector(postNotificationToPresentPushMessagesVC) 
         withObject:nil 
         afterDelay:1]; 
     } 
    } 

    return YES; 
} 

-(void)postNotificationToPresentPushMessagesVC 
{  
    [[NSNotificationCenter defaultCenter]postNotificationName:@"recievePush" object:userInfoDic]; 
} 

在所有VC

：

- (void) viewWillAppear:(BOOL)animated 
{ 
    [super viewWillAppear:animated]; 

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(recievePush:) name:@"recievePush" object:nil]; 

} 

- (void) recievePush : (NSNotification *) notif 
{ 
    NSDictionary *dict = notif.object; 

// do something with message data 
}
