我想在unerInfo中使用cutom对象的userInfo中,但它不起作用。当我将自定义对象放入UserInfo中时,未触发通知。
使用此代码,发出了通知:
let content = UNMutableNotificationContent()
content.title = "title"
content.body = "body"
content.categoryIdentifier = "alarmNotificationCategory"
content.sound = UNNotificationSound.default()
content.userInfo = ["myKey": "myValue"] as [String : Any]
let request = UNNotificationRequest(identifier: "alarmNotification", content: content, trigger: nil)
UNUserNotificationCenter.current().add(request) { error in
UNUserNotificationCenter.current().delegate = self
if error != nil {
print(error!)
}
}
使用以下内容,没有错误,但未触发通知:
let content = UNMutableNotificationContent()
content.title = "title"
content.body = "body"
content.categoryIdentifier = "alarmNotificationCategory"
content.sound = UNNotificationSound.default()
content.userInfo = ["myKey": TestClass(progress: 2)] as [String : Any]
let request = UNNotificationRequest(identifier: "alarmNotification", content: content, trigger: nil)
UNUserNotificationCenter.current().add(request) { error in
UNUserNotificationCenter.current().delegate = self
if error != nil {
print(error!)
}
}
TestClass是自定义类,这是定义:
class TestClass: NSObject, NSSecureCoding {
public var progress: Float = 0
required override public init() {
super.init()
}
public init(progress: Float) {
self.progress = progress
}
public required convenience init?(coder aDecoder: NSCoder) {
self.init()
progress = aDecoder.decodeObject(forKey: "progress") as! Float
}
public func encode(with aCoder: NSCoder) {
aCoder.encode(progress, forKey: "progress")
}
public static var supportsSecureCoding: Bool {
get {
return true
}
}
}
有什么想法?
您对象应该是属性列表
该字典中的键必须是属性列表类型,也就是说 必须是可以序列化为属性列表格式的类型。 有关属性列表类型的信息,请参阅属性列表 编程指南。
您可以将对象转换为NSDATA(使用NSarchiver存档)
