I'm trying to put Facebook posting functionality into an iOS app of mine. I'm following the Facebook tutorial, and it tells me to put this code into my AppDelegate, which I've just migrated from Objective-C:
import UIKit
import FBSDKCoreKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
ApplicationDelegate.shared.application(
application,
didFinishLaunchingWithOptions: launchOptions
)
return true
}
func application(
_ app: UIApplication,
open url: URL,
options: [UIApplication.OpenURLOptionsKey : Any] = [:]
) -> Bool {
ApplicationDelegate.shared.application(
app,
open: url,
sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplication.OpenURLOptionsKey.annotation]
)
}
}
There is no "ApplicationDelegate" in my code; what should I do?
This is the code for both Google-signin and Facebook-signin. Google-signin works perfectly fine but Facebook "SDKApplicationDelegate" won't seem to work. I have imported all my pod (import FacebookCore, Facebook Login, FacebookShare).
Why is SDKApplication not working?
import UIKit
import GoogleSignIn
import FacebookCore
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
GIDSignIn.sharedInstance().clientID = "1043921468178-epj1ms4mnc4tbf2j3vb0kudggfmtnc8b.apps.googleusercontent.com"
GIDSignIn.sharedInstance().delegate = self
return SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
let googleDidHandle = GIDSignIn.sharedInstance().handle(url as URL?,
sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplication.OpenURLOptionsKey.annotation])
let facebookDidHandle = SDKApplicationDelegate.shared.application(app, open: url, options: options)
return googleDidHandle || facebookDidHandle
}
I was facing same problem, the solution I found was to import FBSDKCoreKit and rename it to ApplicationDelegate, but what I've done is to downgrade version of FacebookCore and FacebookLogin to the previous one (I was using 0.5.0) Facebook SDK seems to have a lot of bugs on this new version, I advise you to do the same.
I'm using iOS 10 Swift 3 to integrate FB Login. I have followed all steps from Facebook documentation. Now the issue is, after successful login it doesn't returning any values and not get back the user to the app.
Note: The same works perfectly in Swift 2.
Hi I raised this issue to facebook developer support and the issue is that I have not implemented the correct delegate methods for iOS10. and you can find the correct delegate implementation here
import UIKit
import CoreData
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
public func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
// Override point for customization after application launch.
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
public func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(
app,
open: url as URL!,
sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String,
annotation: options[UIApplicationOpenURLOptionsKey.annotation]
)
}
public func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(
application,
open: url as URL!,
sourceApplication: sourceApplication,
annotation: annotation)
}
}
Don't forget to set Keychain Sharing
project targets -> Capabilities -> Keychain Sharing -> Toggle Switch ON
you can follow this

for me the "FBSDKApplicationDelegate" doesn't work for the latest Facebook Swift SDK version v0.2.0
You can find my implementation for v0.2.2 here: https://gist.github.com/mbecker/bdbd28cd11394085c01cf442aaa42c72

Tested and worked.
Since above answers are indicated as deprecated code, I have changed the syntax.

I have experienced the same problem with Facebook and Twitter integration.I have solved it as follows.
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
let appname:String = options.first?.value as! String
print(appname)
if appname == "com.facebook.Facebook" {
return FBSDKApplicationDelegate.sharedInstance().application(
app,
open: url as URL!,
sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String,
annotation: options[UIApplicationOpenURLOptionsKey.annotation]
)
}
return Twitter.sharedInstance().application(app, open: url, options: options)
}
public func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return SDKApplicationDelegate.shared.application(app, open: url, options: options)
}
Add this in addition to what you have in AppDelegate
Somehow the below code didn't work for me
public func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
return SDKApplicationDelegate.shared.application(application, open: url)
}
So had to change it to
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
let options = [UIApplication.OpenURLOptionsKey.sourceApplication: sourceApplication as Any,
UIApplication.OpenURLOptionsKey.annotation: annotation]
return SDKApplicationDelegate.shared.application(application, open: url, options: options)
}
I am a new developer, and I am currently making my first app.
Sometimes when I try to open the app, the icon dims, but nothing happens, and the whole phone briefly becomes unresponsive. My guess is this is happening in app delegate. I'm not sure what is happening, but I think I should be using grand central dispatch.
this is currently my code in app delegate,
import UIKit
import Firebase
import FirebaseMessaging
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
//Facebook SharedInstance FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
//Firebase Database
FIRApp.configure()
FIRDatabase.database().persistenceEnabled = true
//Onesignal PushNotifications
_ = OneSignal(launchOptions: launchOptions, appId: "3b2b4845-0b6a-4e92-892f-254c2cf51da8", handleNotification: nil)
_ = OneSignal(launchOptions: launchOptions, appId: "3b2b4845-0b6a-4e92-892f-254c2cf51da8", handleNotification: { (message, additionalData, isActive) in
NSLog("OneSignal Notification opened:\nMessage: %#", message)
if additionalData != nil {
NSLog("additionalData: %#", additionalData)
// Check for and read any custom values you added to the notification
// This done with the "Additonal Data" section the dashbaord.
// OR setting the 'data' field on our REST API.
if let customKey = additionalData["customKey"] as! String? {
NSLog("customKey: %#", customKey)
}
}
}, autoRegister: true)
print("didFinishLaunchingWithOptions launchOptions")
return true
}
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
print("application")
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}
Is it possible, that this has nothing to do with app delegate?
if it is in app delegate how can use GCD to make this work
remove
import FirebaseMessaging
and
FIRDatabase.database().persistenceEnabled = true
from the AppDeleget and try running it
I have two test apps: App1 & App2.
App1 takes String from the text field and triggers method:
#IBAction func openApp(sender: AnyObject) {
let url1 = ("app2://com.application.started?displayText="+textToSend.text!)
let url2 = url1.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
UIApplication.sharedApplication().openURL(NSURL(string: url2!)!)
}
Which actually opens App2 which has only label which should change to the text sent through the url, code is within AppDelegate.swift:
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
let url = url.standardizedURL
let query = url?.query
ViewController().labelToDisplayResult.text = query
return true;
}
Unfortunately the line where I am trying to pass result of the URL to the actual label is giving me this error:
EXC_BAD_INSTRUCTION (CODE=EXC_I386_INVOP SUBCODE=0x0)
However I have all the data in the App2 for sure as I can see their values in debugger:
url NSURL "app2://com.application.started?displayText=564315712437124375" 0x00007fa4e3426320
query String? "displayText=564315712437124375"
Any idea why I am getting this error?
Thanks...
Your error
ViewController().labelToDisplayResult.text = query
ViewController() Create a new instance of ViewController,not the one loaded from storyboard.I guess labelToDisplayResult is an outlet, so it is nil,so you get EXC_BAD_INSTRUCTION (CODE=EXC_I386_INVOP SUBCODE=0x0)
This is what I usually do to handle openURL scheme,need to think about two states:
Target App is launched before,so when open url happen,the target app is in background or inactive state
Target App is not launched,so when open url happen,the target app is not running at all
In Appdelegate
class AppDelegate: UIResponder, UIApplicationDelegate {
var openUrl:NSURL? //This is used when to save state when App is not running before the url trigered
var window: UIWindow?
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
let url = url.standardizedURL
NSNotificationCenter.defaultCenter().postNotificationName("HANDLEOPENURL", object:url!)
self.openUrl = url
return true;
}
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
return true
}
}
Then in the ViewController handle openURL
class ViewController: UIViewController {
#IBOutlet weak var testLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self, selector: "handleOpenURL:", name:"HANDLEOPENURL", object: nil)
let delegate = UIApplication.sharedApplication().delegate as? AppDelegate
if let url = delegate?.openUrl{
testLabel.text = url.description
delegate?.openUrl = nil
}
}
func handleOpenURL(notification:NSNotification){
if let url = notification.object as? NSURL{
testLabel.text = url.description
}
}
deinit{
NSNotificationCenter.defaultCenter().removeObserver(self, name: "HANDLEOPENURL", object:nil)
}
}
