我有一个工作应用程序,其中的通知看起来很好。现在我想处理一些通知事件,比如当用户点击横幅时。
我的iOS部署目标是11.0,与我的部署目标相同。
我在AppDelegate.swift文件中实现了所有内容:
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, RCTBridgeDelegate {
var window: UIWindow?
var didFinishLaunching: Bool = false
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
let bridge = RCTBridge(delegate: self, launchOptions: launchOptions)
let rootView = RCTRootView(bridge: bridge, moduleName: "root", initialProperties: nil)
rootView?.backgroundColor = UIColor(red: 1.0, green: 1.0, blue: 1.0, alpha: 1)
self.window = UIWindow(frame: UIScreen.main.bounds)
let rootViewController = UIViewController()
rootViewController.view = rootView
self.window?.rootViewController = rootViewController
self.window?.makeKeyAndVisible()
didFinishLaunching = true
Fabric.with([Crashlytics.self])
FirebaseApp.configure()
// This block is necessary to ask user authorization to receive notification
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(grant, error) in
if error == nil {
if grant {
print("### permission granted")
application.registerForRemoteNotifications()
} else {
//User didn't grant permission
}
} else {
print("error: ",error)
}
})
} else {
// Fallback on earlier versions
let notificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(notificationSettings)
}
self.firstLaunchAction()
self.initTracker()
RNSplashScreen.showSplash("LaunchScreen", inRootView: rootViewController.view)
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { data -> String in
return String(format: "%02.2hhx", data)
}
let token = tokenParts.joined()
print("### Device Token: \(token)")
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("### Failed to register for remote notifications with error: \(error)")
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
if response.actionIdentifier == "like" {
print("### Handle like action identifier")
} else if response.actionIdentifier == "save" {
print("### Handle save action identifier")
} else {
print("### No custom action identifiers chosen")
}
// Make sure completionHandler method is at the bottom of this func
completionHandler()
}
如您所见,我使用Firebase发送远程通知,因此我有一个json格式的负载,如下所示:
return {
notification: {
title,
body
},
data: {
title,
body,
...data
},
android: {
ttl: 3600 * 1000,
notification: {
icon: 'stock_ticker_update',
color: '#002559'
}
},
apns: {
payload: {
aps: {
alert: {
title: 'NITL ACUMEN BI RFS CODA Dev Offshore',
body: 'Send a Message - PN testing group'
},
sound: 'default'
}
}
},
condition
};
我的大部分代码是从网站上复制的。但我的实际行为是,当我点击通知横幅时,什么都没有发生。。。
我看到了nofication横幅,所以我认为我的APNs注册没有问题。我不知道为什么didReceive不是点击触发事件。
我的实现中是否遗漏了某些内容?我的通知负载错误?
有人能帮我找出我的错误在哪里吗?我读过无数没有结果的教程。如果您能帮忙,我将不胜感激,谢谢:)
最佳答案
要支持后台更新通知,请确保有效负载的aps
字典包含值为1的content-available
键。
{
"aps" : {
"content-available" : 1,
"sound" : “default"
....
},
....
}
当后台更新通知发送到用户的设备时,iOS会在后台唤醒你的应用程序,并给它最多30秒的运行时间。在iOS中,系统通过调用app delegate的
application: didReceiveRemoteNotification: fetchCompletionHandler:
方法来传递后台更新通知。参考:Creating the Remote Notification Payload
