【问题描述】：

我想要在收到通知时可操作的按钮。 为了处理远程推送通知，我添加了以下代码 -

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
UIApplication *application = [UIApplication sharedApplication];

if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) ) 
    UIMutableUserNotificationAction *action1 = [[UIMutableUserNotificationAction alloc] init];
    [action1 setActivationMode:UIUserNotificationActivationModeForeground];
    [action1 setTitle:@"action1Text"];
    [action1 setIdentifier:@"action1id"];
    [action1 setDestructive:NO];
    [action1 setAuthenticationRequired:NO];

    UIMutableUserNotificationCategory *actionCategory = [[UIMutableUserNotificationCategory alloc] init];
    [actionCategory setIdentifier:kMTNRemindLaterCategory];
    [actionCategory setActions:@[action1]
                    forContext:UIUserNotificationActionContextDefault];

    NSSet *categories = [NSSet setWithObject:actionCategory];
    UIUserNotificationType types = (UIUserNotificationTypeAlert|
                                    UIUserNotificationTypeSound|
                                    UIUserNotificationTypeBadge);

    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:categories];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

完美运行。我能够看到按钮并处理操作。现在，单击按钮并基于更多逻辑，我想使用与上面定义的相同的可操作按钮安排本地通知。我添加了代码（不在 AppDelegate 文件中）：

NSDate *date = [NSDate dateWithTimeIntervalSinceNow:10];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = date;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.alertBody = @"title 4";
localNotification.hasAction = YES;
localNotification.alertAction = @"action";
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.category = kRemindLaterCategory;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

已安排本地通知，我收到通知。但我没有看到任何可操作的按钮。

我在哪里阅读了苹果文档

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

似乎很有用。但这会在单击通知时触发。 我提到的其他帖子： https://www.shinobicontrols.com/blog/ios8-day-by-day-day-25-notification-actions actions and categories don't show in UILocalNotification in iOS How can I add action buttons/actions to UILocalNotification alert?

谁能指点我正确的方向？

【参考方案1】：

kRemindLaterCategory 值和 kMTNRemindLaterCategory 值应该相同，然后您也可以看到带有本地通知的可操作按钮，如果两者不相同，则可操作按钮不可见因为带有本地通知的指定类别尚未注册。

你是最棒的！非常感谢：D
