在application:didFinishLaunchingWithOptions:我初始化一个UINavigationController.后来,我添加UINavigationController到窗口:

[self.window addSubview:navigationController.view]

一切正常.现在我向我的应用添加了本地通知,当用户响应一个时,我想提出一个UIViewController.所以我想我可以覆盖application:didReceiveLocalNotification:并在那里使用我的navigationController:

[navigationController pushViewController:someVC animated:YES];

但是,这不起作用.我做了一些调试,并注意到虽然navigationController不是nil,navigationController.view但没有superview,所以我认为它没有被显示.

所以,我的问题是:我应该在哪里推动UIViewController它以便显示它？

我目前正在安排本地通知,如果用户当天尚未打开应用程序,则每天下午6点出现一次.如果用户已经加载了应用程序,那么我想取消当天的通知,并在明天下午6点安排新的通知.但是,当我尝试迭代计划通知列表(这不是我在应用程序中的唯一本地通知)时,通知会正确显示,[[UIApplication sharedApplication] scheduledLocalNotifications]数组始终为空.以下是给我带来麻烦的代码段:

// See if we need to create a local notification to tell the user that they can receive a daily reward
NSArray *notifications = [[UIApplication sharedApplication] scheduledLocalNotifications]; // <- This is always empty
// Iterate over all the pending notifications
for( int iter = 0; iter < [notifications count]; iter++ )
{
    UILocalNotification* localNotification = [notifications objectAtIndex:iter];

    if( [[localNotification.userInfo objectForKey:@"source"] isEqualToString:@"dailyReminder"] )
        [[UIApplication sharedApplication] cancelLocalNotification:localNotification];
}

NSCalendar* calendar = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease];
[calendar setTimeZone:[NSTimeZone localTimeZone]];
NSDateComponents …

概观

• 我正在基于现有的实例创建通知 UILocalNotification
• 现有实例已repeatInterval设置为NSWeekdayCalendarUnit

我想做的事

• 我想不设repeatInterval重复,

题

• repeatInterval为了不重复,我应该设定的常数是多少？

我似乎无法找到一个明确的线程来回答这些问题:

"当应用程序未运行时(即不在前台或后台),预定的UILocalNotification是否会触发"？

"当应用程序未运行时(即不在前台或后台)并且手机处于锁定/睡眠模式时,UILocalNotifications是否会触发？"

一些答案表明他们会像UILocalNotifications由iOS操作系统处理.有些人似乎暗示只有在应用程序在后台或前台运行时才会触发.如果手机被锁定,我无法找到有关UILocalNotifications是否有效的信息.

谢谢,詹姆斯

我在我的应用程序中使用本地通知,我唯一关心的是用户点击的确切通知.

方法

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

收到通知时触发,但我需要在用户点击时处理通知,这对我来说没用.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

仅在应用程序未运行时触发,也不是我需要的

我在网上搜索,但发现应用程序处于活动状态或未运行时只有句柄.当应用程序在后台时,我该如何处理它？

换句话说,我需要的是识别用户在应用程序在后台运行时单击的确切通知

我正在尝试制作闹钟应用,但当我尝试发出本地通知时,我无法播放声音.我收到了这个错误:

[user info = (null)} with a sound but haven't received permission from the user to play sounds]

这是代码:

@IBOutlet var setAlaram: UIDatePicker!


@IBAction func setAlarmButton(sender: AnyObject) {

    var dateformater = NSDateFormatter()
    dateformater.timeZone = NSTimeZone .defaultTimeZone()
    dateformater.timeStyle = NSDateFormatterStyle.ShortStyle
    dateformater.dateStyle = NSDateFormatterStyle.ShortStyle

    var datetimestring = NSString()
    datetimestring = dateformater.stringFromDate(setAlaram.date)
    println(datetimestring)

    [self .localnotification(setAlaram.date)]

}

func localnotification (firedate:NSDate)  {

    var localNotification:UILocalNotification = UILocalNotification()
    localNotification.fireDate = firedate
    localNotification.alertBody = "time to woke up"
    localNotification.soundName = "alarm.wav"
    UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

}

override func viewDidLoad() {
    super.viewDidLoad() …

当我的应用程序进入后台时,将 自动调用applicationDidEnterBackground,并在此方法中触发本地通知.但didReceiveLocalNotification:方法未被调用

- (void)applicationDidEnterBackground:(UIApplication *)application {

UIApplication *app = [UIApplication sharedApplication];
bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
    bgTask = UIBackgroundTaskInvalid;
}];

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.fireDate = [NSDate date];
localNotification.alertBody = textString;
localNotification.alertAction = @"View";
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber =  1;

[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];
}

我正在尝试添加/安排提供两个操作的本地通知,如下所示:

如果我已经在使用手机,我还希望将通知显示为横幅提示,我可以向下滑动以查看操作.

现在,我已成功安排通知,它确实出现在锁定屏幕上.但是,当我向左滑动,然后点击"查看",我看不到我的动作.

这是我的代码:

func addNewNotificationWith (name: String, date: Date) {
    let message = "You will see this, but can't do anything! lol."
    let newLocalNotif = UILocalNotification()
    newLocalNotif.fireDate = dueDateWarningTime
    newLocalNotif.alertBody = message
    newLocalNotif.timeZone = TimeZone.autoupdatingCurrent
    newLocalNotif.soundName = UILocalNotificationDefaultSoundName
    newLocalNotif.category = "DueDates"

    let ignoreAction = getNotificationAction(identifier: "", btnTitle: "Ignore")
    let doneAction = getNotificationAction(identifier: "", btnTitle: "Done")

    let category = UIMutableUserNotificationCategory()
    category.identifier = "DueDates"
    category.setActions([ignoreAction, doneAction], for: UIUserNotificationActionContext.minimal)

    let settings = UIUserNotificationSettings(types: .alert, categories: [category])
    UIApplication.shared.registerUserNotificationSettings(settings)

    UIApplication.shared.scheduleLocalNotification(newLocalNotif)
    print("New notification added.")
} …

我在安排多个通知的for循环内安排本地通知时遇到麻烦。例如，该函数接收一个称为的变量repetition，它是一个工作日数组，目的是在该数组中的每个工作日调度通知。问题是，只有一个工作日和一个预定的通知时才会触发通知。当数组中有1个以上的项目时，不会触发任何通知。为了清晰起见，这是完整的功能：

func scheduleNotification(at date: Date, every repetition: [String], withName name: String, id: String) {

    print("Scheduling notifications for the following days: \(repetition) \n \n")

    var components = DateComponents()
    let calendar = Calendar.current

    let hour = calendar.component(.hour, from: date)
    let minutes = calendar.component(.minute, from: date)

    components.hour = hour
    components.minute = minutes

    for rep in repetition {
        switch rep {
            case "Sunday"   : components.weekday = 1
            case "Monday"   : components.weekday = 2
            case "Tuesday"  : components.weekday = 3
            case "Wednesday": components.weekday …

由于UILocalNotification在iOS 10中已弃用，因此我已使用UNUserNotification框架更新了本地通知流程。

当应用程序位于前台时，它会使用AVPlayer播放自定义声音，并且可以正常工作。但是在后台模式下，当触发本地通知时，会播放默认的通知声音，而不是自定义声音。

let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationStringForKey("reminder!", arguments: nil)
content.body = NSString.localizedUserNotificationStringForKey("Reminder body.", arguments: nil)
if let audioUrl == nil {
    content.sound = UNNotificationSound.defaultSound()
} else {
    let alertSound = NSURL(fileURLWithPath: self.selectedAudioFilePath)
    content.sound = UNNotificationSound(named: alertSound.lastPathComponent!)
}
content.userInfo = infoDic as [NSObject : AnyObject]
content.badge = 1
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: false)
let identifier = "Reminder-\(date)"
let request = UNNotificationRequest(identifier: identifier, …
