也没有用，并说无法分配类型＆＃39; UIUserNotificationSettings.Type

的不可变表达式

Answer 1

尝试这样设置：

    var categories: Set = Set(object: firstCategory)
    UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Alert, UIUserNotificationType.Badge categories: categories))

Answer 2

这应该有效：

var categories = Set(arrayLiteral: firstCategory)
var mySettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge], categories: categories)

你的第二行中有太多=。此外，您需要使用Set而不是NSSet。
