ios - 迁移到 iOS10 时无法调用 UNNotificationCategory 类型的初始化程序
<p><p>我正在使用一个示例项目来处理新通知,从 Swift 2.2 过渡到 Swift 2.3,也从 iOS 9 过渡到 iOS 10。我正在使用下面的代码,取自 <a href="http://cleanswifter.com/ios-10-local-notifications/" rel="noreferrer noopener nofollow">this example</a> :</p>
<pre><code>@available(iOS 10.0, *)
func setupAndGenerateLocalNotification() {
// Register an Actionable Notification
let highFiveAction = UNNotificationAction(identifier: NotificationActions.HighFive.rawValue, title: "High Five", options: [])
//next line is an error:
let category = UNNotificationCategory(identifier: "wassup", actions: , minimalActions: , intentIdentifiers: [], options: [.customDismissAction])
//Cannot invoke initializer for type 'UNNotificationCategory' with an argument list of type '(identifier: String, actions: _, minimalActions: _, intentIdentifiers: _, options: _)'
UNUserNotificationCenter.current().setNotificationCategories()
let highFiveContent = UNMutableNotificationContent()
highFiveContent.title = "Wassup?"
highFiveContent.body = "Can I get a high five?"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
let highFiveRequestIdentifier = "sampleRequest"
let highFiveRequest = UNNotificationRequest(identifier: highFiveRequestIdentifier, content: highFiveContent, trigger: trigger)
UNUserNotificationCenter.currentNotificationCenter().addNotificationRequest(highFiveRequest) { (error) in
// handle the error if needed
print(error)
}
}
</code></pre>
<p>我得到的错误是</p>
<pre><code>Cannot invoke initializer for type 'UNNotificationCategory' with an argument list of type '(identifier: String, actions: _, minimalActions: _, intentIdentifiers: _, options: _)'
</code></pre></p>

<p><p>你没有提到你的错误是什么,但我怀疑你复制的代码是为比你安装的更早的测试版编写的。</p>
<p>我在工作中使用的是 Swift 3,而不是 Swift 2.3。在那里,从 Xcode 8 beta 5 开始,您应该将 <code>UNUserNotificationCenter.currentNotificationCenter().addNotificationRequest</code> 更改为 <code>UNUserNotificationCenter.current().add</code>,并删除 <code>minimalActions: ,</code> 来自您的 <code>UNNotificationCategory</code>。可能只有后者可能适用于 Swift 2.3?</p>
<p>我希望这能让你继续前进,但请注意:这可能会在 iOS 10 最终版之前再次发生变化。特别是,我怀疑 <code>current()</code> 可能会变成 <code>current</code>。</p></p>
