Question

我为我的应用设置了远程通知，其工作原理如下。如果用户点击通知的正文，它会调用一个函数（将用户带到特定的ViewController）。然而，当用户点击其中一个动作按钮时，按钮的动作与身体轻击动作一样执行。如何让动作按钮仅执行其动作，而身体也不会执行其动作。

这是我的代码示例：

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    completionHandler([.alert,.sound,.badge])
}

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    let userInfo = response.notification.request.content.userInfo as! [String:AnyHashable]

    // parse userInfo and execute a function in SWReveal to show the appropriate ViewController

    let action = response.actionIdentifier

    if action == "acceptFriendRequest" {
        print("Friend Request Accepted")
    }
}

func setCategories() {
    if #available(iOS 10.0, *) {
        let acceptFriendRequest = UNNotificationAction(
            identifier: "acceptFriendRequest",
            title: "Accept",
            options: [])
        let rejectFriendRequest = UNNotificationAction(identifier: "rejectFriendRequest", title: "Reject", options: [.destructive])
        let FrReq = UNNotificationCategory(
            identifier: "FrReq",
            actions: [acceptFriendRequest, rejectFriendRequest],
            intentIdentifiers: [],
            options: [.customDismissAction])}

我认为没有办法完全避免被调用的方法，因为它是委托方法。但是，函数开头的一个简单的guard语句应该做同样的技巧：

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    guard response.actionIdentifier != "acceptFriendRequest" && response.actionIdentifier != "rejectFriendRequest" else { return }

    let userInfo = response.notification.request.content.userInfo as! [String:AnyHashable]

    // parse userInfo and execute a function in SWReveal to show the appropriate ViewController

}

这样，如果动作标识符与任何一个动作相匹配，即按下了动作按钮，则不会执行该功能的其余部分。
