不确定,缺少什么,但我遇到了一个奇怪的问题!!!
通知声音,但不显示。
我已将该应用程序注册为仅显示警报和声音,奇怪的是它从未显示。可以看到通知添加成功。但是,似乎有些琐碎的事情我无法理解。
即使删除通知也有效。

import NotificationCenter
import UserNotifications

private let categoryIdentifier = "notificationCategory"

notificationCategory.setActions([playMusicAction], forContext: UIUserNotificationActionContext.Minimal)
let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Sound], categories: NSSet(object: notificationCategory) as? Set<UIUserNotificationCategory>)
// if (notificationSettings.types != UIUserNotificationType.None){
UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
// }
}
}
而且,在 AppDelegate...
private let notificationManager = NotificationManager()
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
notificationManager.registerForNotifications(application)
}
