Question

我已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，它工作得很好。但是，当应用程序关闭/未运行时，当用户点击通知中的LAUNCH时，应用程序将启动主屏幕，然后返回主屏幕。

我在这里尝试过很多代码解决方案，大多数涉及这些方面：

- (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，但现在变为黑色这是我的代码，任何人都可以帮我弄清楚这里要做什么？请不要，我正在使用Dreamweaver / phonegap来构建应用程序。

Answer 1

对于本地通知，您需要在以下内容中添加以下内容：

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

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

Answer 2

事实证明......

我不确定它为什么会崩溃，但是如果遇到这个问题的其他任何人遇到此问题，通知会在您的构建进行重新启动时启动应用程序....它只是在它构建时似乎不起作用/运行调试或其他状态。

所以当你运行时，运行RELEASE并且它应该可以正常工作！

从本地通知启动时，iOS应用程序崩溃
