ios - 在 Swift、iOS 8,9 中应用前台时推送本地通知
<p><p>在IOS10中，我使用了UNMutableNotificationContent并设置了委托(delegate)，</p>
<pre><code>private func pushNotification() {
let content = UNMutableNotificationContent()
content.title = "aaa"
content.body = "bbb"
content.subtitle = "00000"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false)
let requestIdentifier = "com.aaaaa.bbbbb"
let request = UNNotificationRequest(identifier: requestIdentifier, content: content, trigger: trigger)
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().add(request) { error in
if error == nil {
print("Time Interval Notification scheduled: \\\\(requestIdentifier)")
}
}
}
</code></pre>
<p>在前台发送通知，调用了以下函数<br/>
然后我可以通过“completionHandler”在前台显示通知</p>
<pre><code>@available(iOS 10.0, *)
public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Swift.Void) {
completionHandler([.alert, .sound])
}
</code></pre>
<p>.<br/>
.<br/>
. </p>
<p>但在 IOS8 和 9 中，我使用了 UILocalNotification </p>
<pre><code>private func pushNotification2() {
let notification = UILocalNotification()
notification.alertAction = "Title Message"
notification.alertBody = "Body Message"
notification.fireDate = NSDate(timeIntervalSinceNow: 0) as Date
notification.soundName = UILocalNotificationDefaultSoundName
notification.category = "INVITE_CATEGORY"
UIApplication.shared.scheduleLocalNotification(notification)
}
</code></pre>
<p>并在 AppDelegate 中找到这些</p>
<pre><code>func application(_ application: UIApplication, didReceive notification: UILocalNotification) {
}
func application(_ application: UIApplication, handleActionWithIdentifier identifier: String?, for notification: UILocalNotification, completionHandler: @escaping () -> Void) {
}
func application(_ application: UIApplication, handleActionWithIdentifier identifier: String?, for notification: UILocalNotification, withResponseInfo responseInfo: , completionHandler: @escaping () -> Void) {
}
</code></pre>
<p>仅当我在前台发送通知时才调用第一个函数，但第一个函数没有“completionHandler”
我应该怎么办？谢谢你的帮助</p></p>

<p><p>如本 SO <a href="https://stackoverflow.com/questions/30852870/displaying-a-stock-ios-notification-banner-when-your-app-is-open-and-in-the-fore" rel="noreferrer noopener nofollow">post</a> 中所述，在 iOS 10 之前的 iOS 中无法显示 native 通知.</p>
<p>如果您需要支持 iOS 9，则需要使用为此目的而存在的众多第三方库之一。</p>
<p> <a href="https://github.com/moritzdietsche/mdnotificationview" rel="noreferrer noopener nofollow">MDNotificationView</a>是我创建的。您可以传入一个模仿 iOS 中 native 通知外观的自定义 View 。</p>
<pre><code>// If you prefer to create your view with Interface Builder.
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: "CustomView", bundle: bundle)
let views = nib.instantiate(withOwner: self, options: nil)
if 0 < views.count,
let view = views as? UIView {
let notificationView = MDNotificationView(view: view, position: .bottom)
notificationView.delegate = self
notificationView.show()
}
</code></pre>
<p>或</p>
<pre><code>// If you prefer to create your view in code.
let view = YourCustomNotificationUIView()
let notificationView = MDNotificationView(view: view, position: .bottom)
notificationView.delegate = self
notificationView.show()
</code></pre>
<p>此外，您还可以添加委托(delegate)方法:</p>
<pre><code>// MARK: Notification View Delegate
func didTap(notificationView: MDNotificationView) {
}
func notificationDidShow(notificationView: MDNotificationView) {
}
func notificationDidHide(notificationView: MDNotificationView) {
}
</code></pre></p>
