在我的应用程序中，我在我的第一个视图控制器上安排了本地通知。它工作正常。要在“查看”按钮上设置操作，我的代码如下：

//AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UILocalNotification *localNotif =
    [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotif)
    {
// did something Here when app launch by View button of notification
// added row in Db
}  
    return YES;
}

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{

    // Handle the notificaton when the app is running
    NSLog(@"Recieved Notification %@",notif);

    app.applicationIconBadgeNumber=notif.applicationIconBadgeNumber++;
}

问题：它只在第一次工作正常。

但是第二次显示通知，但该行未添加到我的数据库中

// 已编辑

当用户按下“查看”​​按钮时，我想采取一些行动。

我如何识别该操作？

已编辑

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{


    // Handle the notificaton when the app is running
    NSLog(@"Recieved Notification %@",notif);

    app.applicationIconBadgeNumber=notif.applicationIconBadgeNumber++;

    UIApplicationState state = [app applicationState];
    if (state == UIApplicationStateInactive) {
        // Application was in the background when notification
        // was delivered.

        [self localNotif];

    }


}

- (void) localNotif
{

    [self databaseOpen];
    NSString *maxIdPt = [NSString stringWithFormat:@"select Max(id) from Points"];
    NSLog(@"Max id from points table %@",maxIdPt);
    NSMutableArray *p1 = [[NSMutableArray alloc]init];
    p1 = [[[database executeQuery:maxIdPt]mutableCopy]retain];


    int p=[[[p1 objectAtIndex:0]valueForKey:@"Max(id)"]intValue];
    NSLog(@"%d",p);


    NSString *maxPt = [NSString stringWithFormat:@"select Points from Points where id = %d",p];
    NSLog(@"Maxp %@",maxPt);
    NSMutableArray * p2 = [[NSMutableArray alloc]init];
    p2 =[[[database executeQuery:maxPt]mutableCopy]retain];

    int k = [[[p2 objectAtIndex:0]valueForKey:@"Points"]intValue];
    NSLog(@"Points %d",k);

    k = k + 250;

    NSLog(@"%d",k);


    NSString *mtpoints = [NSString stringWithFormat:@"insert into Points(Points) values (%d)",k];
    NSLog(@" lbl Points are %@",mtpoints);
    NSMutableArray * m1 = [[NSMutableArray alloc]init];
    m1 = [[[database executeQuery:mtpoints]mutableCopy]retain];
    [database close];


}

我在应用程序中调用的相同方法didFinishLaunchingWithOptions

第一次更新分数，但第二次没有。甚至没有显示通知。

当用户按下通知中的按钮时，可能第二次didFinishLaunchingWithOptions没有调用该函数，因为应用程序已经在后台运行（而不是从非运行状态启动）。

您还必须处理函数调用

(void)application:(UIApplication *)application 
        didReceiveLocalNotification:(UILocalNotification *)notification {
// do your db update here, too ...
}

为了涵盖您的应用程序已经在后台运行的情况。

编辑：

要查看应用程序是否已启动或已在运行（= 用户在通知上按下“查看”​​而不是应用程序在前台运行），请检查应用程序状态：

UIApplicationState state = [application applicationState];
  if (state == UIApplicationStateInactive) {
    // Application was in the background when notification
    // was delivered.
  }
