Question

我跟着this tutorial显示推送通知上的按钮通过在didFinishLaunchingWithOptions中调用 registerNotification 来注册按钮但是，在少数情况下，我需要显示一个没有任何按钮的简单通知。如何显示/隐藏不同通知的按钮？

Answer 1

要添加其他类型的无按钮的互动式通知，您必须更新UIMutableUserNotificationCategory。

在没有任何按钮的情况下创建新的通知类别UIMutableUserNotificationCategory *newNotificationCategory = [[UIMutableUserNotificationCategory alloc] init]; newNotificationCategory.identifier = @"no_button_id";：

UIUserNotificationSettings

然后，将此新类别添加到现有NSMutableArray *arrNewCategories = [NSMutableArray new]; UIUserNotificationSettings *oldSettings = [[UIApplication sharedApplication]currentUserNotificationSettings]; for (UIMutableUserNotificationCategory *oldCategory in oldSettings.categories) { if (![oldCategory.identifier isEqualToString:newNotificationCategory.identifier]) [arrNewCategories addObject:oldCategory]; } [arrNewCategories addObject:newNotificationCategory]; UIUserNotificationType notificationType = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert; UIUserNotificationSettings *newSettings = [UIUserNotificationSettings settingsForTypes:notificationType categories:[NSSet setWithArray:arrNewCategories]]; [[UIApplication sharedApplication] registerUserNotificationSettings:newSettings];：

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:afireDate];
localNotification.alertBody = @"alert body text";
localNotification.category = @"no_button_id"; //  Same as category identifier
localNotification.timeZone = [NSTimeZone systemTimeZone];
localNotification.soundName = SOUND_FILE;
localNotification.repeatInterval = 0;
[[UIApplication sharedApplication]scheduleLocalNotification:localNotification];

只需确保newNotificationCategory的标识符与您的UILocalNotification类别匹配，您不需要任何按钮。

然后安排通知：

- profile
- dashboard
- setting

我希望这对你有所帮助。

Parameter Description.
    userInfo --> dictionary value for user needs.
    title    --> notitification Title.
    fireDate --> trigger notification date and time.
    Interactive -> pass flag to set Interactive or normal notification.

-(void)setLocalnotfication:(NSDictionary *)userInfo title:(NSString *)title date:(NSDate *)fireDate Interactive : (BOOL)flag {
   UILocalNotification *notification = [[UILocalNotification alloc] init];
   notification.fireDate = fireDate;
   notification.alertBody = title;
   notification.timeZone = [NSTimeZone defaultTimeZone];
   notification.soundName = UILocalNotificationDefaultSoundName;
   if(flag) notification.category = @"Category name";
   if([userInfo isKindOfClass:[NSDictionary class]]) notification.userInfo = userInfo;
   [[UIApplication sharedApplication] scheduleLocalNotification:notification];

}

我正在使用此代码创建它。

更快捷

func setLocalnotfication(userInfo: [NSObject : AnyObject], title: String, date fireDate: NSDate, Interactive flag: Bool) {
    var notification: UILocalNotification = UILocalNotification()
    notification.fireDate = fireDate
    notification.alertBody = title
    notification.timeZone = NSTimeZone.defaultTimeZone()
    notification.soundName = UILocalNotificationDefaultSoundName
    if flag {
    notification.category = NCI
    }
    if (userInfo is NSDictionary.self) {
    notification.userInfo = userInfo
   }
    UIApplication.sharedApplication().scheduleLocalNotification(notification)
}
