uilocalnotification

问题 I need to display a local notification and have it remain on screen longer than the default 4-5 seconds, preferably until the app itself removes it. I've seen other apps (e.g. Pandora) that manage to do this somehow (maybe a push notification?), but I can find no duration property on UILocalNotification or in UIApplication methods like presentLocalNotificationNow: , scheduleLocalNotification: , etc. Neither the documentation nor any of the tutorials I've found address the display time at all.

问题 I have a UILocalNotification , and I don't want to set it to use a default tone.

问题 I am currently scheduling local notifications to appear once per day at 6PM if a user has not already opened the app that day. If the user has already loaded the application, then I want to cancel the notification for that day and schedule a new one for tomorrow at 6PM. The notification displays properly, however, when I try to iterate of the list of scheduled notifications (this is not the only local notification I have in the application), the [[UIApplication sharedApplication]

问题 Is there any way to know if a local notification was dismiss from the Notification Center (for example by pressing the x button)? Is it possible to get a list of all the notifications currently visible in the Notification Center? 回答1: No it's not possible to get list of notifications from any of APIs from Apple. And no there is no feedback from ignored / closed notifications. If you want to implement logic like that, I would propose to build this type of logic based on your own servers. When

问题 I am trying to setup a UILocalNotification to run every 30 seconds using the following logic, however it seems to be misbehaving. There are 2 issues: When the notifications get fired there seems to be a lot of them all at once, rather than 1 every 30 seconds. The application icon badge number doesn't seem to increase. It just stays at 1. Please can someone help me work out what I've done wrong? // Create 'base' notification we can use UILocalNotification *baseNotification = [

问题 there is the possibility of a LocalNotification on the iPhone to load on a date? My problem is that I create an event for the notification but i release the object after creation. Or can I just create a new Object with the same data to delete my Notification? sorry for my english... 回答1: scheduledLocalNotifications will give you the list of all scheduled notifications and use - (void)cancelLocalNotification:(UILocalNotification *)notification or you can cancel them all using: [[UIApplication

问题 If a UILocalNotification fires with a sound set, and the user taps "Cancel" on the notification alert, the sound is stopped. But if the user taps "View", iOS then delivers the notification to the app and the sound keeps on playing. Is there any way to cancel this sound from the app? Canceling the notification in the app once the notification is delivered doesn't work (I didn't expect it to, the notification has already been delivered after all), and since I don't have the sound's system sound

问题 I want to customize the repeat interval of a UILocalNotification to be on certain days of the week. I haven't found any information about this. How can I program the repeat interval for notifications for certain days of the week, for example, repeat a notification on Sunday, Monday, and Friday? 回答1: Unfortunately you cannot set the repeatInterval property of UILocalNotification to repeat only on particular days. You can set either repeat daily (every day), monthly (every month) or hourly
