Swift中推送通知设置：Binary operator '|' cannot be applied to two UIUserNotificationType operands 错误解决

在swif2.0中，推送设置不能使用|,

如果这么：let setting = UIUserNotificationSettings(forTypes: .Alert|.Badge|.sound, categories: nil )

会提示错误 ：Binary operator '|' cannot be applied to two UIUserNotificationType operands

解决办法：

let setting = UIUserNotificationSettings(forTypes: [.Alert,.Badge,.sound], categories: nil)
