单击本地通知时显示自定义UIViewcontroller

Question

我在 applicationDidEnterBackground 中创建本地通知：

NSString *word;
word=[DictionaryHelper getWordOfTheDay];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];
localNotification.alertBody =("%@",word);
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication]     applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

显示本地通知并打开应用的 rootviewcontroller（初始）。

但是我想在点击本地通知时打开特定的UIViewController ...

Answer 1

只需检查applicationDidFinishLaunchingWithOptions中的词典userInfo即可。如果它包含密钥UIApplicationLaunchOptionsLocalNotificationKey，则表示该应用程序是通过点击本地通知启动的，您可以在userInfo字典中获取对通知对象的引用。

要呈现不同的UIViewController，只需为此情况初始化或实例化viewController，并将其设置为rootVC。​​

您还可以使用该方法来回复通知：

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

Answer 2

在didReceiveLocalNotification中：

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    NSLog(@"Local notification received: %@", notification.alertBody);
    if ([notification.userInfo[@"notificationName"] isEqualToString:@"myLocalNotification"]) {
        [self.window.rootViewController performSegueWithIdentifier:@"MainToNotification" sender:nil];
    }
}
