如何从 AppDelegate 打印 o NSLog？

Question

我只是想看看我的令牌设备。

我就是这样做的：

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

    return true
}

// Successfully registered for push
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let trimEnds = deviceToken.description.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
    let cleanToken = trimEnds.stringByReplacingOccurrencesOfString(" ", withString: "", options: []); print(cleanToken)

    //registerTokenOnServer(cleanToken) //theoretical method! Needs your own implementation
}

// Failed to register for Push
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    NSLog("Failed to get token; error: %@", error) //Log an error for debugging purposes, user doesn't need to know
}

但是print(cleanToken)什么也没做。不知道是不是不能在AppDelegate中使用print。我还创建了一个全局变量并将 cleanToken 保存到该新变量中。然后我在 viewController 中打印它，但它是空的。

您可能运行在模拟器中进行此操作吗？那么您可能不会在 didRegisterForRemoteNotificationsWithDeviceToken 接到电话。您需要运行在实际 phone

Answer 2

已修复。我刚刚收到有关我的应用程序已停用的通知，提示代码无效。我已经卸载了该应用程序并重新安装它，所以它可以完美运行。
