ios - 如何推迟【权限请求提醒】？

Question

我的应用需要这些权限

• 通知
• 全局定位系统
• 照片

当用户打开图库时请求照片权限，但前两个权限显示应用程序启动，我可以将 GPS 作为第一个请求权限，但我想将通知对话框推迟到另一个屏幕，如何做到这一点？

这个library似乎不允许这样做有什么建议吗？

let notificationTypes : UIUserNotificationType = [UIUserNotificationType.Alert,UIUserNotificationType.Badge,UIUserNotificationType.Sound]
let notificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)

application.registerForRemoteNotifications()
application.registerUserNotificationSettings(notificationSettings)

谢谢，这为我解决了，...

从应用委托(delegate)调用

    let notificationTypes : UIUserNotificationType = [UIUserNotificationType.Alert,UIUserNotificationType.Badge,UIUserNotificationType.Sound]
    let notificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    application.registerForRemoteNotifications()
    application.registerUserNotificationSettings(notificationSettings)

从另一个类调用

    let notificationTypes : UIUserNotificationType = [UIUserNotificationType.Alert,UIUserNotificationType.Badge,UIUserNotificationType.Sound]
    let notificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    UIApplication.sharedApplication().registerForRemoteNotifications()
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
