推荐答案

以下方法用于通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
 UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
   if (notification)
   {


   }
}


 -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSString *token = [[[[deviceToken description]
                      stringByReplacingOccurrencesOfString:@"<"withString:@""]
                     stringByReplacingOccurrencesOfString:@">" withString:@""]
                    stringByReplacingOccurrencesOfString: @" " withString: @""];
    NSLog(@"Token:%@",token);

}

//app is forground this method will access
 -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{

}
//need to on teh background fetch option in info plist
//app is background state this below mthod will call while notification receives
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
 {
  NSLog(@"Background mode working%@",userInfo);

  if([userInfo[@"aps"][@"content-available"] intValue]== 1) //it's the silent notification when recive preferences and text messages
  {
  }
 }

//handling interactive notification
   - (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forLocalNotification:(nonnull UILocalNotification *)notification completionHandler:(nonnull void (^)())completionHandler {
  }
