UIUserNotificationSettings不能工作

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

没有工作，并说二进制运算符'|'不能适用于两个“UIUserNotificationType”操作数UIUserNotificationSettings不能工作

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

也没有工作，并表示无法指定类型的不可变的表达“UIUserNotificationSettings.Type

这应该工作：

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，非常感谢，我写错误'：'为'='...... – postman99

有时Swift错误有误导性。 – Mark

尝试设置这样的：

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