在Xcode 8 / Swift 3.0中注册推送通知？

我正在尝试让我的应用程序在Xcode 8.0中运行，并且遇到错误。我知道这段代码在swift的早期版本中可以正常工作，但是我假设在新版本中对此代码进行了更改。这是我要运行的代码：

let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)     
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.shared().registerForRemoteNotifications()

我收到的错误是“参数标签'（forTypes :, Categories :)'与任何可用的重载都不匹配”

我可以尝试使用其他命令来使其正常工作吗？

导入UserNotifications框架并UNUserNotificationCenterDelegate在AppDelegate.swift中添加

请求用户权限

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {


        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
            // Enable or disable features based on authorization.
        }
        application.registerForRemoteNotifications()
        return true
}

获取设备令牌

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print(deviceTokenString)
}

发生错误时

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

        print("i am not available in simulator \(error)")
}

如果您需要知道授予的权限

UNUserNotificationCenter.current().getNotificationSettings(){ (settings) in

            switch settings.soundSetting{
            case .enabled:

                print("enabled sound setting")

            case .disabled:

                print("setting has been disabled")

            case .notSupported:
                print("something vital went wrong here")
            }
        }

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    if #available(iOS 10, *) {

        //Notifications get posted to the function (delegate):  func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void)"


        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in

            guard error == nil else {
                //Display Error.. Handle Error.. etc..
                return
            }

            if granted {
                //Do stuff here..

                //Register for RemoteNotifications. Your Remote Notifications can display alerts now :)
                DispatchQueue.main.async {
                    application.registerForRemoteNotifications()
                }
            }
            else {
                //Handle user denying permissions..
            }
        }

        //Register for remote notifications.. If permission above is NOT granted, all notifications are delivered silently to AppDelegate.
        application.registerForRemoteNotifications()
    }
    else {
        let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    }

    return true
}

import UserNotifications  

接下来，转到目标的项目编辑器，然后在“常规”选项卡中查找“链接的框架和库”部分。

单击+并选择UserNotifications.framework：

// iOS 12 support
if #available(iOS 12, *) {  
    UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound, .provisional, .providesAppNotificationSettings, .criticalAlert]){ (granted, error) in }
    application.registerForRemoteNotifications()
}

// iOS 10 support
if #available(iOS 10, *) {  
    UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
    application.registerForRemoteNotifications()
}
// iOS 9 support
else if #available(iOS 9, *) {  
    UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
    UIApplication.shared.registerForRemoteNotifications()
}
// iOS 8 support
else if #available(iOS 8, *) {  
    UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
    UIApplication.shared.registerForRemoteNotifications()
}
// iOS 7 support
else {  
    application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
}

使用通知委托方法

// Called when APNs has assigned the device a unique token
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {  
    // Convert token to string
    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print("APNs device token: \(deviceTokenString)")
}

// Called when APNs failed to register the device for push notifications
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {  
    // Print the error to console (you should alert the user that registration failed)
    print("APNs registration failed: \(error)")
}

用于接收推送通知

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    completionHandler(UIBackgroundFetchResult.noData)
}

设置推送通知将为您的应用启用Xcode 8中的功能。只需转到目标的项目编辑器，然后单击“ 功能”选项卡。查找推送通知，并将其值切换为ON。

检查下面的链接以获取更多的通知委托方法

处理本地和远程通知UIApplicationDelegate - 处理本地和远程通知

https://developer.apple.com/reference/uikit/uiapplicationdelegate

在将deviceToken Data对象转换为字符串以使用当前Xcode 8 beta发送到我的服务器时，这里的答案存在问题。尤其是像8.0b6中那样使用deviceToken.description的字符串，它将返回“ 32字节”，不是很有用:)

这就是对我有用的...

在Data上创建扩展以实现“ hexString”方法：

extension Data {
    func hexString() -> String {
        return self.reduce("") { string, byte in
            string + String(format: "%02X", byte)
        }
    }
}

然后，当您从注册远程通知中收到回调时，可以使用它：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let deviceTokenString = deviceToken.hexString()
    // Send to your server here...
}

在iOS10中而不是您的代码中，您应该使用以下内容请求进行通知的授权：（不要忘记添加UserNotifications框架）

if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().requestAuthorization([.alert, .sound, .badge]) { (granted: Bool, error: NSError?) in
            // Do something here
        }
    }

另外，正确的代码是您的（else例如，在上一个条件中使用）：

let setting = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared().registerUserNotificationSettings(setting)
UIApplication.shared().registerForRemoteNotifications()

最后，确保Push Notification在target-> Capabilities-> 下被激活Push notification。（将其设置为On）

好吧，这对我来说工作。AppDelegate中的第一名

import UserNotifications

然后：

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        registerForRemoteNotification()
        return true
    }

    func registerForRemoteNotification() {
        if #available(iOS 10.0, *) {
            let center  = UNUserNotificationCenter.current()
            center.delegate = self
            center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
                if error == nil{
                    UIApplication.shared.registerForRemoteNotifications()
                }
            }
        }
        else {
            UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
            UIApplication.shared.registerForRemoteNotifications()
        }
    }

要获取设备令牌：

  func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

       let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})

}

请注意，您应该使用主线程执行此操作。

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
        if granted {
            DispatchQueue.main.async(execute: {
                UIApplication.shared.registerForRemoteNotifications()
            })
        }
    }

首先，监听用户通知状态，即registerForRemoteNotifications()获取APNs设备令牌；
其次，要求授权。当得到用户授权时，deviceToken将被发送到侦听器AppDelegate；
第三，向您的服务器报告设备令牌。

extension AppDelegate {
    /// 1. 监听 deviceToken
    UIApplication.shared.registerForRemoteNotifications()

    /// 2. 向操作系统索要推送权限（并获取推送 token）
    static func registerRemoteNotifications() {
        if #available(iOS 10, *) {
            let uc = UNUserNotificationCenter.current()
            uc.delegate = UIApplication.shared.delegate as? AppDelegate
            uc.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
                if let error = error { // 无论是拒绝推送，还是不提供 aps-certificate，此 error 始终为 nil
                    print("UNUserNotificationCenter 注册通知失败, \(error)")
                }
                DispatchQueue.main.async {
                    onAuthorization(granted: granted)
                }
            }
        } else {
            let app = UIApplication.shared
            app.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil)) // 获取用户授权
        }
    }

    // 在 app.registerUserNotificationSettings() 之后收到用户接受或拒绝及默拒后，此委托方法被调用
    func application(_ app: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
        // 已申请推送权限，所作的检测才有效
        // a 征询推送许可时，用户把app切到后台，就等价于默拒了推送
        // b 在系统设置里打开推送，但关掉所有形式的提醒，等价于拒绝推送，得不token，也收不推送
        // c 关掉badge, alert和sound 时，notificationSettings.types.rawValue 等于 0 和 app.isRegisteredForRemoteNotifications 成立，但能得到token，也能收到推送（锁屏和通知中心也能看到推送），这说明types涵盖并不全面
        // 对于模拟器来说，由于不能接收推送，所以 isRegisteredForRemoteNotifications 始终为 false
       onAuthorization(granted: app.isRegisteredForRemoteNotifications)
    }

    static func onAuthorization(granted: Bool) {
        guard granted else { return }
        // do something
    }
}

extension AppDelegate {
    func application(_ app: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        //
    }

    // 模拟器得不到 token，没配置 aps-certificate 的项目也得不到 token，网络原因也可能导致得不到 token
    func application(_ app: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        //
    }
}

ast1的答案非常简单实用。它对我有用，非常感谢。我只想在这里说出来，因此需要此答案的人可以轻松找到它。所以，这是我注册本地和远程（推送）通知的代码。

    //1. In Appdelegate: didFinishLaunchingWithOptions add these line of codes
    let mynotif = UNUserNotificationCenter.current()
    mynotif.requestAuthorization(options: [.alert, .sound, .badge]) {(granted, error) in }//register and ask user's permission for local notification

    //2. Add these functions at the bottom of your AppDelegate before the last "}"
    func application(_ application: UIApplication, didRegister notificationSettings: UNNotificationSettings) {
        application.registerForRemoteNotifications()//register for push notif after users granted their permission for showing notification
}
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print("Device Token: \(tokenString)")//print device token in debugger console
}
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print("Failed to register: \(error)")//print error in debugger console
}

只需在中执行以下操作didFinishWithLaunching:：

if #available(iOS 10.0, *) {

    let center = UNUserNotificationCenter.current()

    center.delegate = self
    center.requestAuthorization(options: []) { _, _ in
        application.registerForRemoteNotifications()
    }
}

请记住有关导入语句：

import UserNotifications

看看下面的注释代码：

import Foundation
import UserNotifications
import ObjectMapper

class AppDelegate{

    let center = UNUserNotificationCenter.current()
}

extension AppDelegate {

    struct Keys {
        static let deviceToken = "deviceToken"
    }

    // MARK: - UIApplicationDelegate Methods
    func application(_: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

        if let tokenData: String = String(data: deviceToken, encoding: String.Encoding.utf8) {
            debugPrint("Device Push Token \(tokenData)")
        }

        // Prepare the Device Token for Registration (remove spaces and < >)
        setDeviceToken(deviceToken)
    }

    func application(_: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        debugPrint(error.localizedDescription)
    }

    // MARK: - Private Methods
    /**

     */
    func registerRemoteNotification() {

        center.requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in

            // Enable or disable features based on authorization.
            if granted  == true {

                DispatchQueue.main.async {
                    UIApplication.shared.registerForRemoteNotifications()
                }
            } else {
                debugPrint("User denied the permissions")
            }
        }
    }

    /**
     Deregister remote notification
     */
    func deregisterRemoteNotification() {
        UIApplication.shared.unregisterForRemoteNotifications()
    }

    func setDeviceToken(_ token: Data) {
        let token = token.map { String(format: "%02.2hhx", arguments: [$0]) }.joined()
        UserDefaults.setObject(token as AnyObject?, forKey: “deviceToken”)
    }

    class func deviceToken() -> String {
        let deviceToken: String? = UserDefaults.objectForKey(“deviceToken”) as? String

        if isObjectInitialized(deviceToken as AnyObject?) {
            return deviceToken!
        }

        return "123"
    }

    func isObjectInitialized(_ value: AnyObject?) -> Bool {
        guard let _ = value else {
                return false
         }
            return true
    }
}

extension AppDelegate: UNUserNotificationCenterDelegate {

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping(UNNotificationPresentationOptions) -> Swift.Void) {

        ("\(notification.request.content.userInfo) Identifier: \(notification.request.identifier)")

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

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping() -> Swift.Void) {

        debugPrint("\(response.notification.request.content.userInfo) Identifier: \(response.notification.request.identifier)")

    }
}

让我知道是否有任何问题！
