UILocalNotification 不发送
UILocalNotification doesn't send
我正在尝试发送这样的 UILocalNotification
:
func sendNotifiaction() {
let notification = UILocalNotification()
notification.userInfo = [
"Identifier": self.identifier!
]
notification.alertTitle = "Alarm!"
notification.alertBody = "test"
//notification.soundName = "Temporary-bleep-sound.aiff"
notification.category = "category"
UIApplication.sharedApplication().scheduleLocalNotification(notification)
}
我试图在这个方法上设置一个断点,它正在被调用并且运行,但是根本没有发送通知。
有人知道为什么吗?
你得先注册通知
UIApplication.sharedApplication().cancelAllLocalNotifications()
let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
这是我在特定时间触发通知的演示
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
UIApplication.sharedApplication().cancelAllLocalNotifications()
let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
let localNotification1 = UILocalNotification()
localNotification1.alertBody = "Your alert message at 9:00 pm"
localNotification1.timeZone = NSTimeZone.defaultTimeZone()
localNotification1.fireDate = self.getNinePMDate()
UIApplication.sharedApplication().scheduleLocalNotification(localNotification1)
return true
}
func getNinePMDate() -> NSDate? {
let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let now: NSDate! = NSDate()
let date21h = calendar.dateBySettingHour(21, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)
return date21h
}
}
您应该在 appdelegate
中实施 didReceiveLocalNotification
并且您必须手动显示带有标题和消息的警报视图作为通知的 alertbody
。
