我收到推送通知并根据通知的内容显示 View Controller 。当 postman 手动触发通知时，我得到以下userInfo
[AnyHashable("google.c.a.e"): 1, AnyHashable("gcm.notification.type"): new_property, AnyHashable("gcm.notification.meta"): {"property_id":"3"}, AnyHashable("gcm.message_id"): 1570614460795417, AnyHashable("aps"): {
alert = {
body = "A new property has been published is in your area";
title = "New Property";
};
}]
// CASTING AS [String: Any]
["google.c.a.e": 1, "gcm.notification.meta": {"property_id":"3"}, "gcm.notification.type": new_property, "aps": {
alert = {
body = "A new property has been published is in your area";
title = "New Property";
};
}, "gcm.message_id": 1570614460795417]
这反过来会工作并显示所需的屏幕。但是，当用户操作触发相同的通知时，我会收到此 userInfo
[AnyHashable("gcm.notification.meta"): {"property_id":46}, AnyHashable("gcm.notification.type"): new_property, AnyHashable("body"): A new property has just been listed in your area by Ebenezer Kilani, AnyHashable("title"): New property Listing, AnyHashable("type"): new_property, AnyHashable("meta"): {"property_id":46}, AnyHashable("aps"): {
alert = {
body = "A new property has just been listed in your area by Ebenezer Kilani";
title = "New property Listing";
};
}, AnyHashable("gcm.message_id"): 1570550088749025, AnyHashable("google.c.a.e"): 1]
// CASTING AS [String: Any]
["meta": {"property_id":46}, "type": new_property, "title": New property Listing, "gcm.message_id": 1570550088749025, "gcm.notification.meta": {"property_id":46}, "body": A new property has just been listed in your area by Ebenezer Kilani, "aps": {
alert = {
body = "A new property has just been listed in your area by Ebenezer Kilani";
title = "New property Listing";
};
}, "google.c.a.e": 1, "gcm.notification.type": new_property]
第二个有效负载只是打开应用程序，但从未进入我需要的 View Controller 。也就是说，它仅打开主页。
我如何获取用户信息
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
if let usrInfo = userInfo as? [String: Any] {
extractUserInfo(userInfo: usrInfo, completion: completionHandler)
}
completionHandler()
}
func extractUserInfo(userInfo: [String: Any], completion: @escaping () -> Void) {
if let type = userInfo["gcm.notification.type"] as? String {
Storage.instance.savePush(type)
if type == "new_property" {
if let meta = userInfo["gcm.notification.meta"] as? String {
if let data = meta.data(using: .utf8) {
do {
if let json = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String: Any] {
guard let propertyId = json["property_id"] as? String, let id = Int(propertyId) else {return}
NotificationEvent.isFromNotification.accept(true)
NotificationEvent.id.accept(id)
} else {
print("JSON is invalid")
}
} catch {
print("Exception converting: \(error)")
}
}
}
}
}
}
我如何处理显示所需 View Controller 的推送
class Remote {
var navigationController: UINavigationController?
let disposeBag = DisposeBag()
@discardableResult
init(navigationController: UINavigationController?) {
self.navigationController = navigationController
rxEvent()
}
func rxEvent() {
NotificationEvent.isFromNotification.asObservable().subscribe(onNext: { bool in
print("Exception converting: bool \(bool)")
if bool {
NotificationEvent.id.asObservable()
.delay(1, scheduler: MainScheduler.instance)
.subscribe(onNext: { int in
if int > 0 {
if Storage.instance.getPush() == "new_property" {
self.presentPropertyDetailVC(int)
} else if Storage.instance.getPush() == "new_rating" || Storage.instance.getPush() == "coverage_area" {
print(int)
}
}
}).disposed(by: self.disposeBag)
NotificationEvent.isFromNotification.accept(false)
}
}).disposed(by: disposeBag)
}
func presentPropertyDetailVC(_ uid: Int) {
// navigationVC.modalPresentationStyle = .formSheet
let controller = PropertyDetailVC()
controller.propertyId = uid
print("Exception converting: 11 \(controller)")
navigationController?.pushViewController(controller, animated: true)
}
}
然后我在我的家庭 VC 中实例化 Remote
第一个有效负载工作而第二个有效负载无效的任何原因以及我可以采取的任何措施来纠正该问题。
最佳答案
这一行
guard let propertyId = json["property_id"] as? String, let id = Int(propertyId) else {return}
正在进入“返回”，因为在第二个元 46 上是一个 int 而不是字符串(请注意，它没有引号。要修复它，您可以尝试
guard let propertyId = json["property_id"] as? String ?? String(json["property_id"] as? Int ?? 0), let id = Int(propertyId) else {return}
