I am trying to get the value for launchOptions from UIApplicationDelegate
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
If the launchOptions is a NSDictionary I probably can retrieve value by
launchOptions[launchOptions.UIApplicationLaunchOptionsRemoteNotificationKey]
But the object is [NSObject: AnyObject]. How to retrieve value for this type?
Your variant is not safe, better use if let statement:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if let options = launchOptions as? [String: AnyObject],
notifyPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] {
// do smth with notifyPayload
}
return true
}
Swift is full of try and adjust
Here is my own answer.
let notifPayload = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey as String!] as? NSDictionary

I want to open my iOS app from and URL but when I put NSURL into fund application print() doesn't working.
please refer here
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var openUrl:NSURL? //This is used when to save state when App is not running before the url trigered
func application(_ application: UIApplication, openURL url: NSURL, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
//print("Host: \(url.host!)")
//let url = url.standardized
//NotificationCenter.default.post(name: NSNotification.Name(rawValue: "HANDLEOPENURL"), object:url!)
print("bbb")
return true
}
}
There is no AppDelegate method with that signature, so its not getting called
func application(_ application: UIApplication, openURL url: NSURL, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
The correct method signature is:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool`
You are confusing it with this method
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
EDIT
To respond to links from the web to iOS, use
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([Any]?) -> Void) -> Bool {
This is my Swift 3 code:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if let userInfo : Foundation.NSDictionary = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? Foundation.NSDictionary {
self.setNavigationInfoFromPushNotification(userInfo: userInfo)
navigateFromPushNotification()
}
...
}
It results in a compile-time error that says:
Ambiguous reference to member 'Subscript'
Please can anyone help me with this?
The method signature has changed. See How to handle launch options in Swift 3 when a notification is tapped? Getting syntax problems.
It is now:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
if let userInfo = launchOptions?[.remoteNotification] as? NSDictionary {
setNavigationInfoFromPushNotification(userInfo: userInfo)
navigateFromPushNotification()
}
...
}
Recently converted a project to Swift 2.2 and running into issues that didn't exist prior. I've tried searching for a workaround but haven't found any similar posts.
Use of undeclared type 'UIApplicationLaunchOptionsKey'.
I can't tell what's wrong with this code in the AppDelegate.swift:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
//UIToolbar.appearance().tintColor = UIColor.clearColor()
return true
}
Try changing the method signature to
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
return true
}
The signature is modified to func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool in swift 3
In Swift 3 the method is changed to:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
I'm building an app with Swift that receives push notifications. I am sending custom values inside the JSON.
I am opening the app through the notification, so I know that I have to do this inside "didFinishLaunchingWithOptions" and read the value from "launchOptions".
How can I read those values and use them on my app.
Many thanks.
Here's what works for me in SWIFT 2 when your app is not launched. The code is not quite elegant because of the optional bindings. But it works.
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
}
In the application:didReceiveRemoteNotification:fetchCompletionHandler, The custom data is in passed on to the didReceiveRemoteNotification, which is an NSDictionary. The details that you want to retrieve is probably on the "aps" key of the userInfo.
func application(application: UIApplication, didReceiveRemoteNotification userInfo: NSDictionary!)
{
var notificationDetails: NSDictionary = userInfo.objectForKey("aps") as NSDictionary
}
When the app is not launched, you will need to get it from the application:didFinishedLaunchWithOptions,
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
if let launchOpts = launchOptions {
var notificationDetails: NSDictionary = launchOpts.objectForKey(UIApplicationLaunchOptionsRemoteNotificationKey) as NSDictionary
}
return true
}
EDIT: Remote Notification Fix syntax
This is the Oliver Zhang response which is updated for Swift 5.
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[UIApplication.LaunchOptionsKey.remoteNotification] {
}
}
return true
}
I am finding this error in my AppDelegate.swift file and it appears in the AppDidFinishLaunchingWithOptions function. It is raising the error on a line of code that is from the Parse framework.
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
The error is appearing on the launchOptions parameter. I will post the whole function to show that it should be correct. Also when I comment out the line of code the error disappears, but I still really want to be able to use the function and track the analytics. Here is the whole function:
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: AnyObject!) -> Bool
{
// Override point for customization after app launches
Parse.setApplicationId("removed on purpose", clientKey: "removed on purpose")
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
PFFacebookUtils.initializeFacebook()
return true
}
I can't seem to find anything that relates to this error. If anyone has some insight I would really appreciate it!
Since Xcode 6 beta 7, when you want to call application:didFinishLaunchingWithOptions:, you have to replace:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
/* ... */
}
with the following code:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
/* ... */
}
The last parameter of this method is no more a NSDictionary but a Dictionary of type [NSObject: AnyObject]?. Therefore, you must update your code (including your trackAppOpenedWithLaunchOptions: parameter type).
The launchOptions parameter should be declared as NSDictionary! instead of AnyObject!:
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
// ...
}
