iPhone 城市飞艇发射选项问题

Question

我有一个非常简单的问题，搜索并没有引导我找到答案。在我的 application:didFinishLaunchingWithOptions 方法中，我执行以下操作来恢复程序未运行时传入的通知：

 //Init Airship launch options
 NSMutableDictionary *takeOffOptions = [[[NSMutableDictionary alloc] init] autorelease];
 [takeOffOptions setValue:launchOptions forKey:UAirshipTakeOffOptionsLaunchOptionsKey];
 [UAirship takeOff:takeOffOptions];
 [UAPush shared].delegate = self;
 [[UAPush shared] resetBadge];

 // Register for notifications through UAPush for notification type tracking
 [[UAPush shared] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                      UIRemoteNotificationTypeSound |
                                                      UIRemoteNotificationTypeAlert)];

当程序运行时（在前台或后台），我可以这样恢复我的飞艇警报：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
 NSLog(@"\nReceived remote notification:\n%@\n\n", userInfo);

 [[UAPush shared] handleNotification:userInfo applicationState:application.applicationState];
 [[UAPush shared] resetBadge]; // zero badge after push received

 NSString *alertMessage = [[userInfo objectForKey:@"aps"] valueForKey:@"alert"];
}

我的问题是：什么当程序在前台或后台运行时，我可以执行命令序列来从 userInfo 中提取与从 userInfo 中获取的相同信息，或者从程序未运行时发送的消息中的 launchOptions 中提取相同的信息吗？提前致谢 ：）

Answer 1

NSDictionary *userInfo = [launchOptions valueForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"];

NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

NSString *alertMsg = [apsInfo objectForKey:@"alert"];
