我为我的应用设置了每日提醒本地通知。当应用程序在后台时效果很好。但是，当应用程序关闭/未运行时，当用户在通知中点击 LAUNCH 时，应用程序会启动主屏幕，然后返回主屏幕。

我在这里尝试了许多代码解决方案，其中大部分涉及以下内容：

- (BOOL)application:(UIApplication *)application 
  didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (notification) {
        // handle your notification here.
    }
}

但无论我把它放在哪里，应用程序都会启动，但现在变成黑色。
这是我的代码，谁能帮我弄清楚在这里做什么？请不要，我正在使用 Dreamweaver/phonegap 来构建应用程序。

对于本地通知，您需要在中添加以下内容：

- (void)applicationDidFinishLaunchingWithOptions:(UIApplication *)application
{ 
     UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
}

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

事实证明...

我不确定它为什么会崩溃，但是如果其他人遇到此问题，则通知将在您为 relase 构建时启动应用程序....它在构建/运行时似乎不起作用调试或其他状态。

因此，当您运行时，运行 RELEASE，它应该可以正常工作！
