ios - Action From Local Notification Opened (iOS)

Question

I've searched other questions similar to this here and I can't find any that seem to actually work. What I'm trying to do is when the user opens the app from a local notification, I need it to execute some code (such as opening the UIMessageComposer or displaying a UIAlertView). Anyone have any idea on how I would do this? Just as a note it is a local notification not a push notification.

Answer 1

您需要在AppDelegate.m文件 中实现此方法

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification

你可以做你想要的。

Answer 2

用这个

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIApplicationState state = [application applicationState];

if (state == UIApplicationStateActive) {

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Reminder"
                                                    message:notification.alertBody
                                                   delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
}

    // Set icon badge number to zero
    application.applicationIconBadgeNumber = 0;
}
