在Xcode 8/Swift 3.0中注册推送通知？
在Xcode 8/Swift 3.0中注册推送通知？
提问于 2016-06-22 08:01:27
我正在尝试让我的应用程序在Xcode8.0中工作，但遇到错误。我知道这个代码在以前的swift版本中运行得很好，但我假设新版本中的代码已经改变了。下面是我要运行的代码：
let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.shared().registerForRemoteNotifications()我得到的错误是“参数标签'(forTypes:，categories:)‘不匹配任何可用的重载”
有没有不同的命令，我可以试着让它工作？

导入
UserNotifications框架并在AppDelegate.swift中添加UNUserNotificationCenterDelegate
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)
}错误情况下的
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("i am not available in simulator \(error)")
}如果需要知道授予的权限，则为
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")
}

import UserNotifications 接下来，转到目标的项目编辑器，并在General选项卡中查找Linked Frameworks and Libraries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)
}设置推送通知正在为您的应用程序启用Xcode8中的功能。只需转到目标的项目编辑器，然后单击Capabilities选项卡即可。查找推送通知，并在上将其值切换为。
