ios - 注册本地和远程通知

Question

这就是我们注册本地通知的方式

if UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:"))  {
    UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound], categories: nil));
}

我们如何为远程做同样的事情？ 有没有办法让我们可以一次注册并为两者工作？

Answer 1

您可以编写一个包装函数来同时注册两者:

func initializeNotificationServices() {
    let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings) //Local notifications

    // This is an asynchronous method to retrieve a Device Token. You have to implement callbacks in AppDelegate to use the device token.
    UIApplication.sharedApplication().registerForRemoteNotifications()
}
