当应用程序在前台时，iOS Swift 接收推送通知

Question

这是我在前台应用程序时用来接收推送通知的代码

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void)
{
     completionHandler([UNNotificationPresentationOptions.Alert,UNNotificationPresentationOptions.Sound,UNNotificationPresentationOptions.Badge])
}

但我的问题是我的通知包含 [NSObject : AnyObject] 值。如何接收点赞后台通知

Answer 1

将此代码添加到 AppDelegate.swift 文件中。

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
{
    completionHandler([UNNotificationPresentationOptions.alert,UNNotificationPresentationOptions.sound,UNNotificationPresentationOptions.badge])
}
