在 iOS 9 中注册通知 [英] Register notification in iOS 9

问题描述

我用它来注册通知:

if application.respondsToSelector("registerUserNotificationSettings:") {
                let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
                let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)

                application.registerUserNotificationSettings(settings)
                application.registerForRemoteNotifications()

            } else {
                // Register for Push Notifications before iOS 8
                application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
            }

但它不适用于 iOS 9.

推荐答案

我找到了解决方案:

 if application.respondsToSelector("registerUserNotificationSettings:") {
        if #available(iOS 8.0, *) {
            let types:UIUserNotificationType = ([.Alert, .Sound, .Badge])
            let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)
            application.registerUserNotificationSettings(settings)
            application.registerForRemoteNotifications()
        } else {
            application.registerForRemoteNotificationTypes([.Alert, .Sound, .Badge])
        }
    }
    else {
        // Register for Push Notifications before iOS 8
        application.registerForRemoteNotificationTypes([.Alert, .Sound, .Badge])
    }
