UIUserNotificationSettings不能工作

var categories: NSSet = NSSet(object: firstCategory) 
let types: UIUserNotificationType = UIUserNotificationType.Badge | UIUserNotificationType.Alert

沒有工作，並說二進制運算符'|'不能適用於兩個「UIUserNotificationType」操作數UIUserNotificationSettings不能工作

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

也沒有工作，並表示無法指定類型的不可變的表達「UIUserNotificationSettings.Type

這應該工作：

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

你有太多=在你的第二行。此外，您需要使用Set而不是NSSet。

哇，非常感謝，我寫錯誤'：'爲'='...... – postman99

有時Swift錯誤有誤導性。 – Mark

嘗試設置這樣的：

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