[英]get the value from launchOptions at application(… launchOptions: [NSObject: AnyObject]?)
[英]How to get custom Push Notification value from launchOptions with swift?
我正在使用Swift構建一個接收推送通知的應用程序。 我在JSON中發送自定義值。
我通過通知打開應用程序,所以我知道我必須在“didFinishLaunchingWithOptions”中執行此操作並從“launchOptions”中讀取值。
如何閱讀這些值並在我的應用程序中使用它們。
非常感謝。
當您的應用未啟動時,這是適用於SWIFT 2的功能。 由於可選的綁定,代碼不是很優雅。 但它的確有效。
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// if launched from a tap on a notification
if let launchOptions = launchOptions {
if let userInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] {
if let action = userInfo["action"], id = userInfo["id"] {
let rootViewController = self.window!.rootViewController as! ViewController
let _ = setTimeout(5.0, block: { () -> Void in
rootViewController.openNotification(action as! String, id: id as! String)
})
}
}
}
return true
}
在應用程序中:didReceiveRemoteNotification:fetchCompletionHandler,自定義數據傳遞給didReceiveRemoteNotification,這是一個NSDictionary。 您要檢索的詳細信息可能位於userInfo的“aps”鍵上。
func application(application: UIApplication, didReceiveRemoteNotification userInfo: NSDictionary!)
{
var notificationDetails: NSDictionary = userInfo.objectForKey("aps") as NSDictionary
}
當應用程序未啟動時,您需要從應用程序中獲取它:didFinishedLaunchWithOptions,
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
if let launchOpts = launchOptions {
var notificationDetails: NSDictionary = launchOpts.objectForKey(UIApplicationLaunchOptionsRemoteNotificationKey) as NSDictionary
}
return true
}
