我在循环中创建通知,相关代码是:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
appDelegate = self
serNotificationType = UIUserNotificationType.Alert.union(UIUserNotificationType.Sound).union(UIUserNotificationType.Badge)
let completeAction = UIMutableUserNotificationAction()
completeAction.identifier = "COMPLETE" // the unique identifier for this action
completeAction.title = "Clear" // title for the action button
completeAction.activationMode = .Background // UIUserNotificationActivationMode.Background - don't bring app to foreground
completeAction.authenticationRequired = false // don't require unlocking before performing action
completeAction.destructive = true // display action in red
let callInAction = UIMutableUserNotificationAction()
callInAction.identifier = "CALLIN"
callInAction.title = "Call now"
callInAction.destructive = false
callInAction.authenticationRequired = false
callInAction.activationMode = UIUserNotificationActivationMode.Background
callInAction.destructive = false
let notificationCategory = UIMutableUserNotificationCategory() // notification categories allow us to create groups of actions that we can associate with a notification
notificationCategory.identifier = "CALLINNOTIFICATION"
notificationCategory.setActions([callInAction, completeAction], forContext: .Default) //UIUserNotificationActionContext.Default (4 actions max)
notificationCategory.setActions([completeAction, callInAction], forContext: .Minimal) //UIUserNotificationActionContext.Minimal - for when space is limited (2 actions max)
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: notificationTypes, categories: NSSet(array:[notificationCategory]) as? Set<UIUserNotificationCategory>))
return true
}
通知的调度是在for循环中完成的(也许这就是调度出错的原因):
func scheduleLocalNotifications() {
let arrayOfEvents: [[Meeting]] = CalendarController.sharedInstance.getAllMeetings()
//remove CallIn notifications anyway
self.removeScheduledNotifications()
var limitCounter = 0 //limit is 64 local notifications
print("scheduling start: \(CallIn.Settings.notifyNumberOfMinutesBeforeEvent)")
for var x = 0; x < arrayOfEvents.count; x++ {
for var y = 0; y < arrayOfEvents[x].count; y++ {
let event = arrayOfEvents[x][y]
if(event.startTime.timeIntervalSinceDate(NSDate()) > -2000 && limitCounter <= 64){
if(notificationsAreAllowed()){
let notification = UILocalNotification()
let minutesBefore = CallIn.Settings.notifyNumberOfMinutesBeforeEvent
notification.fireDate = event.startTime.dateByAddingTimeInterval(-minutesBefore * 60) //time of launch of notification
if(minutesBefore <= 1){
notification.alertBody = "Your \(event.title) is about to start"
}else{
notification.alertBody = "You have \(event.title) in \(Int(minutesBefore)) minutes"
}
notification.alertAction = "OK"
notification.soundName = UILocalNotificationDefaultSoundName
notification.userInfo = ["title": event.title, "UUID": event.UUID, "CallIn": "CallInNotification"]
notification.category = "CALLINNOTIFICATION"
notification.applicationIconBadgeNumber = 1
UIApplication.sharedApplication().scheduleLocalNotification(notification)
}
limitCounter += 1
}
}
}
}
答案 0 :(得分:6)
好的,我发现了这个问题,这可能对将来的某个人有用:
我有
UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
在应用程序的两个不同位置被调用两次(因为我在应用程序中进行了设置,需要从设置页面进行更改)。 因此,当重构并调用一次时,它就可以工作。
