输入代码：

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

 if（notification）{
 //从通知启动
} else {
 //从跳板
} 
} 
 

在 UIApplicationDelegate 。 p>

I would like to know if there is a way to know if an app (which can be closed or open in background) has been launched with a click on:

• a notification (in the notification center) ?
• or the app icon on the springboard ?

Thanks !!

put this code:

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

    if (notification) {
        // launched from notification
    } else {
        // from the springboard
    }
}

in your UIApplicationDelegate.
