在iOS 10中,有一个选项可以在应用程序处于前台时使用 UNNotificationPresentationOptions 显示通知,
但是我找不到任何关于如何使用它的示例,请提出一些关于如何实现此功能的建议

我已经通过
实现了前台通知在我的viewController中添加以下代码
extension UIViewController: UNUserNotificationCenterDelegate {
public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Swift.Void) {
completionHandler( [.alert, .badge, .sound])
}
public func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Swift.Void) {
print("Do what ever you want")
}
}
在关于didFinishLaunchingWithOptions的Appdelegate中
UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.sound]) {(accepted, error) in
if !accepted {
print("Notification access denied")
}
}

新的iOS 10 UNUserNotificationCenterDelegate现在有一套处理远程和本地通知的方法。
UNUserNotificationCenterDelegate
协议:
userNotificationCenter(_:didReceive:withCompletionHandler:)
要求您的应用知道用户为给定通知选择了哪个操作。
userNotificationCenter(_:willPresent:withCompletionHandler:)
向在前台运行的应用发送通知。
两种方法。更好的是,现在他们已经转移到他们自己的协议,即iOS 10
UNUserNotificationCenterDelegate
所以这将有助于清理现有的UIApplicationDelegat
e,因为它能够将所有旧的通知处理代码重构为一个闪亮的,新的,有凝聚力的协议。
以下是一个例子:
extension NotificationManager: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
switch response.actionIdentifier {
// NotificationActions is a custom String enum I've defined
case NotificationActions.HighFive.rawValue:
print("High Five Delivered!")
default: break
}
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
// Delivers a notification to an app running in the foreground.
}
}
