Question

我正试图迅速发送通知。这是我在appdelegate.swift文件中注册通知的代码

application.registerUserNotificationSettings(
    UIUserNotificationSettings(
        forTypes:UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound, categories: nil))

我收到此错误：

二元运算符＆＃39; |＆＃39;两个UIUserNotificationType＆＃39;操作数。

如果你能帮助我找到解决这个问题的解决办法，那就太好了。

谢谢

Answer 1

试试这个

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

首先：导入UserNotification

import UserNotifications

第二：然后将委托添加到appDelegate：

class AppDelegate: UIResponder, **UIApplicationDelegate**

第三：然后注册通知：

if #available(iOS 10.0, *)
        {
            let center = UNUserNotificationCenter.currentNotificationCenter()
            center.delegate = self
            //center.setNotificationCategories(nil)
            center.requestAuthorizationWithOptions([.Alert,.Badge,.Sound]) {
                granted,error in
                if (error == nil) {
                    UIApplication.sharedApplication().registerForRemoteNotifications()
                }
            }
        }

Swift 3.0

 if #available(iOS 10.0, *) {
        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
            // Enable or disable features based on authorization. 
        }
    }
    else
    {
        UIApplication.shared.registerUserNotificationSettings(UIUser‌NotificationSettings‌(types: [.sound, .alert, .badge], categories: nil))
    }
    UIApplication.shared.registerForRemoteNotifications()

Swift 4.0

上面的步骤然后在主线程上注册通知，如：

DispatchQueue.main.async(execute: {
              UIApplication.shared.registerForRemoteNotifications()
})

如果你在AppDelegate里面试试这个

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil))
    UIApplication.sharedApplication().cancelAllLocalNotifications()

    return true
}

UIUserNotificationSettings拒绝接受swift中的多种通知类型
