I am integrating chartboost into my sprite kit game and have successfully integrated bridging files into my swift code. Now in my app delegate I have the following:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let kChartboostAppID = "5554c8680d60255c6a0f4af4"
let kChartboostAppSignature = "1d0e271cd054c9a63473d2f1212ca33a2922a19f"
Chartboost.startWithAppId(kChartboostAppID, appSignature: kChartboostAppSignature, delegate: self)
Chartboost.cacheMoreApps(CBLocationHomeScreen)
return true
}
class func showChartboostAds()
{
Chartboost.showInterstitial(CBLocationHomeScreen);
}
func didFailToLoadInterstitial(location: String!, withError error: CBLoadError) {
}
the startWithId line gives me an error that it cant invoke this method with these arguments ( String, String, AppDelegate). This used to work fine on my objective c code.. Anyone knows how to fix this?
class AppDelegate: UIResponder, UIApplicationDelegate, ChartboostDelegate
Edit (from Lalit's comment below)
In startWithAppId the delegate is set to self, so you have to set the class AppDelegate as the delegate, which is done using:
ChartboostDelegate(protocol)

I am trying to connect to my chat server in a Swift app using XMPPFramework, but the didConnect delegate method never gets called.
I have created a basic app in Objective C and I can connect and authenticate in my chat sever without problems.
In the Swift project I tried to connect with the code:
class AppDelegate: UIResponder, UIApplicationDelegate {
var stream:XMPPStream = XMPPStream()
var reconnect:XMPPReconnect = XMPPReconnect()
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
stream.addDelegate(self, delegateQueue: DispatchQueue.main)
stream.myJID = XMPPJID(string: "user#chatserver.net")
reconnect.activate(stream)
do {
try stream.connect(withTimeout: XMPPStreamTimeoutNone)
}
catch let err{
print("error occured in connecting\(String(describing: err.localizedDescription))")
}
return true
}
I’ve debugged XMPPFramework and in the method - (void)handleStreamFeatures a call to the delegate is executed :
[multicastDelegate xmppStreamDidConnect:self];
I’ve watched the multicastDelegateObject and has a node with reference to my delegate, and to OS_dispatch_queue_main, but after execution my xmppStreamDidConnect method isn’t executed.
As it is described in this Github Issue, the problem was the method declaration.
My xmppStreamDidConnect need an underscore, the root problem was that if you don't import the swift extensions the compiler marks that declaration as incorrect, although it works.
So to fix my problem, I need to import the pod 'XMPPFramework/Swift' and change the method declaration to
func xmppStreamDidConnect(_ sender: XMPPStream) {
I've integrated Chartboost into my app and I am able to see ads, but I don't have a firm grasp of delegates and I am having trouble using the Chartboost provided code to cause actions to occur after an ad is viewed. My app delegate code is below (i replaced the actual appid and signature that I'm using):
class AppDelegate: UIResponder, UIApplicationDelegate, ChartboostDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
application.isStatusBarHidden = true
Chartboost.start(withAppId: "appID", appSignature: "appSignature", delegate: self)
Chartboost.cacheRewardedVideo(CBLocationHomeScreen)
Chartboost.cacheInterstitial(CBLocationHomeScreen)
func didDisplayInterstitial(_ location: String!){print("didDisplayI")}
func didCloseInterstitial(_ location: String!){print("didCloseI")}
func didDismissInterstitial(_ location: String!){print("didDismissI")}
return true
}
Then in my ViewController I have the following:
class CharacterCreationViewController: UIViewController, ChartboostDelegate {
weak var delegate: ChartboostDelegate?
Override func viewDidLoad() {
super.viewDidLoad()
Chartboost.setDelegate(self)
}
#IBAction func watchAd(_ sender: Any) {
Chartboost.showInterstitial(CBLocationLevelStart)
delegate?.didDismissInterstitial!(CBLocationLevelStart)
delegate?.didCloseInterstitial!(CBLocationLevelStart)
delegate?.didDisplayInterstitial!(CBLocationLevelStart)
}
The watchAd function is a button, and when I press it the ad runs, but none of the actions in the appDelegate file run once the ad is completed/dismissed/closed.
I've searched StackOverflow and the Chartboost help sections and messaged Chartboost support but I'm struggling to find where I've gone wrong.
Using: XCode 7, iPhone 5 (iOS 8.3), WiFi, Reachability (check the internet connection).
While my app is in background and I click to open my app it checks the conncetion and load some functions and in 1 of the functions I try to sign:
imageView.image = UIImage(named: "imagename")
error: fatal error: unexpectedly found nil while unwrapping an Optional value
This happens only when my app change an IBOutlet value in applicationWillEnterForeground with function to primary view controller
self.viewController.functionName()
class AppDelegate: UIResponder, UIApplicationDelegate {
var viewController:ViewController = ViewController()
func applicationWillEnterForeground(application: UIApplication) {
self.viewController.checkConn()
}
}
checkConn() check the connection with Reachability and change IBOutlets values like .image and .text
Is there any way to fix it?
After a lot of tests I found this method which works great:
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var viewController:ViewController?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
viewController = self.window!.rootViewController as? ViewController
return true
}
func applicationWillEnterForeground(application: UIApplication) {
viewController!.checkConn()
}
}
I am assuming that this is where your crash is happening.
imageView.image = UIImage(named: "imagename")
If you are using "Images.xcassets" to manage your image files. Make sure that "imagename" exists.
After upgrading to Xcode 6.3 6D570 (and Swift 1.2), the init of a subclassed object does not compile.
Let's say I have a class called Armor, which inherits from PFObject, PFSubclassing (exactly as Parse documentation says).
When I try to create an instance, like var armor = Armor(), I get the following compile error:
Missing argument for parameter 'className' in call
Then I read in Parse docs that I should use the 'object' class method to init a subclassed object. So I tried to init like this: var armor = Armor.object().
But then I get the following compile error:
'object()' is unavailable: use object construction 'PFObject()'
I'm using Parse SDK version 1.7.1.
I also override the parseClassName method as follows:
class func parseClassName() -> String {
return "Armor"
}
I registered the subclass inside the initialise method and on app delegate before I setup Parse:
override class func initialize() {
var onceToken : dispatch_once_t = 0;
dispatch_once(&onceToken) {
self.registerSubclass()
}
}
How should I properly init a subclassed object?
=========================================================================
THIS HAS BEEN FIXED IN 1.7.3 PARSE SDK
You can download the new version here:
https://parse.com/docs/downloads
=========================================================================
Though docs are not clear on that, using .object() in Swift is not required anymore.
as said here and in the Swift code snippet found here
Now, this is weird but to make Armor() work you need to reference PFUser class somehow in the same file. Maybe it doesn't have to be PFUser but I havent dug deeper into it.
So, this won't work
import UIKit
import Parse
import Bolts
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
Parse.setApplicationId("appID", clientKey: "clientKey")
let myArmor = Armor()
return true
}
}
But this will
import UIKit
import Parse
import Bolts
private let fix = PFUser.hash() // here's the weird trick
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
Parse.setApplicationId("appID", clientKey: "clientKey")
let myArmor = Armor()
return true
}
}
Hope this helps and Parse pushes a fix out soon.
Also reported as a bug
register the class as a subclass in the AppDelegate, but before Parse.initialize is called.
Then you can delete the overwritten function initialize
This would make:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]!) -> Bool {
Armor.registerSubclass()
// Further initialization
return true
}
then just initialize the class by calling the constructor:
var myArmor = Armor()
I am trying to have users login to facebook with parse but am receiving the compiler error "Use of unresolved identifier" for PFFacebookUtils, Parse, FBAppCall, and an invalid DidBecomeActive
This question has been posted before and the solution was to add the parsefacebookutils framework into your project and import it into the header file. However, I have already added the framework to my project and imported it into my header file by adding the following to the my header.
#import <Parse/Parse.h>
#import <ParseFacebookUtils/PFFacebookUtils.h>
#import <FacebookSDK/facebookSDK.h>
I am still getting the error. The following is the code from my appdelegate file:
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
PFFacebookUtils.initializeFacebook()
Parse.setApplicationId("parseAppId", clientKey:"parseClientKey")
}
return true
}
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String,
annotation: AnyObject?) -> Bool {
return FBAppCall.handleOpenURL(url, sourceApplication:sourceApplication,
withSession:PFFacebookUtils.session())
}
func applicationDidBecomeActive(application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
FBAppCall.handleDidBecomeActiveWithSession(PFFacebookUtils.session())
}
Could you please take a look at my code above? Not sure what the solution is.
Figured it out. You have to go into the Build Settings - Objective C Header and then type the path to your header in the debug name. For example ProjectName/HeaderName.h as according to where I had my file within my project. Normally you wouldn't have to do this, but it didn't populate for me when I created the header.
