Integrating Facebook SDK - ios

I'm making an app and i want integrated Facebook, but this error can't continue, attached my problem.
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
// Override point for customization after application launch.
return true
}
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation:annotation) } THIS IS THE PROBLEM -- > ////Use of unresolved identifier "sourceApplication"///
}
}

Your delegate method does not match the one being used by Facebook. What about something like this?
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(app, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String, annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
}

Is it possible to support both Facebook and Google login in iOS using swift? [duplicate]

My app use google+ signin and in my appdelegate.swift i have:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
GIDSignIn.sharedInstance().delegate = self
return true
}
func application(application: UIApplication,
openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
return GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: sourceApplication,
annotation: annotation)
}
Now i would like to insert also facebook login, but i have to add in appdelegate.swift this code:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(
application,
openURL: url,
sourceApplication: sourceApplication,
annotation: annotation)
}
But this return error because the functions 'application' already exist, how can I perform both google+ and facebook same appdelegate.swift
Thank you.
Your application should handle facebook and google links, then return true if one or the other can handle the given link.
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
let googleDidHandle = GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: sourceApplication,
annotation: annotation)
let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(
application,
openURL: url,
sourceApplication: sourceApplication,
annotation: annotation)
return googleDidHandle || facebookDidHandle
}
And in didFinishLaunching :
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
GIDSignIn.sharedInstance().delegate = self
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
In Swift 3, need to do in this way:
Override and implement the next method:
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
let sourceApplication = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String
let annotation = options[UIApplicationOpenURLOptionsKey.annotation]
let googleHandler = GIDSignIn.sharedInstance().handle(
url,
sourceApplication: sourceApplication,
annotation: annotation )
let facebookHandler = FBSDKApplicationDelegate.sharedInstance().application (
app,
open: url,
sourceApplication: sourceApplication,
annotation: annotation )
return googleHandler || facebookHandler
}
Then:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
PFFacebookUtils.initializeFacebook(applicationLaunchOptions: launchOptions)
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(String(describing: configureError))")
return true
}
in Swift 5 you can do it this way:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FBSDKCoreKit.ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
GIDSignIn.sharedInstance().clientID = "your_client_id"
GIDSignIn.sharedInstance().delegate = self
return true
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
let handledFB = FBSDKCoreKit.ApplicationDelegate.shared.application(app, open: url, options: options)
let handledGoogle = GIDSignIn.sharedInstance().handle(url)
return handledFB || handledGoogle
}

Facebook Authentication - Blank white screen during authentication - iOS 10 GM, Swift 3

Since Swift 3 - iOS 10, Xcode 8 GM SDK, I receive blank white screen at the end of the authentication with Facebook SDK.
It worked before. I have some warnings in the AppDelegate:
maybe it has something to do with it.
Edit:
I understood these functions are deprecated, and I tried changing these to the new functions, but the FBSDKApplicationDelegate still requests the older parameters...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: <#T##String!#>, annotation: <#T##Any!#>)
}
As you see, the problem is now with the second function.
Try this!
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(app,open: url,sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}
I understand these functions are deprecated in iOS 9, so that I used the others functions with their own API.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey
.sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

FB Login using Swift 3 not returning any values and not get back the user to the App after successful login

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)
}

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)
}

Use of unresolved identifier sourceApplication Facebook SDK

The following code to implement FB login into my app
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
However I keep getting two error messages both similar,
"Use of unresolved identifier 'annotation'
"Use of unresolved identifier 'sourceApplication'
I'm not exactly sure what's causing this error but I have a feeling its a bit of code that's been deprecated. Does anyone know what the current alternative is?
appdelegate.swift
I´m using this code in my app delegate and works perfect
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}
You have a variable name mismatch:
You declare your UIApplication as app in the first line, but try to reference it by sourceApplication in your return statement. Replace sourceApplication with app. Same with annotation, change that to options:
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: app, annotation: options)

How to use both google+ and facebook login in same appdelegate.swift

My app use google+ signin and in my appdelegate.swift i have:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
GIDSignIn.sharedInstance().delegate = self
return true
}
func application(application: UIApplication,
openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
return GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: sourceApplication,
annotation: annotation)
}
Now i would like to insert also facebook login, but i have to add in appdelegate.swift this code:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(
application,
openURL: url,
sourceApplication: sourceApplication,
annotation: annotation)
}
But this return error because the functions 'application' already exist, how can I perform both google+ and facebook same appdelegate.swift
Thank you.
Your application should handle facebook and google links, then return true if one or the other can handle the given link.
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
let googleDidHandle = GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: sourceApplication,
annotation: annotation)
let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(
application,
openURL: url,
sourceApplication: sourceApplication,
annotation: annotation)
return googleDidHandle || facebookDidHandle
}
And in didFinishLaunching :
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
GIDSignIn.sharedInstance().delegate = self
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
In Swift 3, need to do in this way:
Override and implement the next method:
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
let sourceApplication = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String
let annotation = options[UIApplicationOpenURLOptionsKey.annotation]
let googleHandler = GIDSignIn.sharedInstance().handle(
url,
sourceApplication: sourceApplication,
annotation: annotation )
let facebookHandler = FBSDKApplicationDelegate.sharedInstance().application (
app,
open: url,
sourceApplication: sourceApplication,
annotation: annotation )
return googleHandler || facebookHandler
}
Then:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
PFFacebookUtils.initializeFacebook(applicationLaunchOptions: launchOptions)
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(String(describing: configureError))")
return true
}
in Swift 5 you can do it this way:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FBSDKCoreKit.ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
GIDSignIn.sharedInstance().clientID = "your_client_id"
GIDSignIn.sharedInstance().delegate = self
return true
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
let handledFB = FBSDKCoreKit.ApplicationDelegate.shared.application(app, open: url, options: options)
let handledGoogle = GIDSignIn.sharedInstance().handle(url)
return handledFB || handledGoogle
}
