I have a singleton class that handles all my game center stuff. I have set it to be a delegate of GKAchievementViewControllerDelegate.
I call the following method showAchievements
- (void) showAchievements
{
GKAchievementViewController *achievements = [[GKAchievementViewController alloc] init];
if (achievements != nil)
{
achievements.achievementDelegate = self.delegate;
[self.viewController presentModalViewController: achievements animated: YES];
}
}
and I implement the following
- (void)achievementViewControllerDidFinish:(GKAchievementViewController *)achievements
{
[self.viewController dismissModalViewControllerAnimated: YES];
}
I set self.viewController with the following code before calling showAchievements
AppController* appDelegate = (AppController*)[[UIApplication sharedApplication] delegate];
[GameCenterManager instance].viewController = appDelegate.window.rootViewController;
The app crashes and the following shows up in the console log when I call showAchievements.
Jul 16 12:36:28 imac-3 myApp[17103] <Info>: 12:36:28.287698 com.apple.AVConference: GKSConnSettings: set server: {
"gk-cdx" = "17.173.254.218:4398";
"gk-commnat-cohort" = "17.173.254.220:16386";
"gk-commnat-main0" = "17.173.254.219:16384";
"gk-commnat-main1" = "17.173.254.219:16385";
}
At the point where I call showAchievements the user has been logged in successfully.
Any idea what I might be doing wrong here?
My suspicions were correct, I was trying to access the viewController in the wrong way. I should have been using the CCDirectorIOS object instead of the UIWindow object.
GKAchievementViewController is deprecated. Try using GKGameCenterViewController.

so I've been reading articles and the Apple developer library for a while but I'm not able to solve this.
I want to have a Game Center Leaderboard for my app, that's accessible through my game menu. However, since I'm using Sprite Kit for creating my game this causing me some problems.
I registered my app in iTunes Connect, enabled Game Center and the Identity information within Xcode matches the ones in iTunes Connect.
I created a button, that should open the Game Center Leaderboard. When it's tapped this is called:
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if (leaderboardController != NULL)
{
leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
leaderboardController.leaderboardDelegate = self;
GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init];
if (gameCenterController != nil)
{
gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
UIViewController *vc = self.view.window.rootViewController;
[vc presentViewController: gameCenterController animated: YES completion:nil];
}
}
Now I get the message, that Game Center is unavailable because no player is signed in.
To fix that I tried using the authentication method from apple:
- (void) authenticateLocalPlayer
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error){
if (viewController != nil)
{
//showAuthenticationDialogWhenReasonable: is an example method name.
[self showAuthenticationDialogWhenReasonable: viewController];
}
else if (localPlayer.isAuthenticated)
{
//authenticatedPlayer: is an example method name.
[self authenticatedPlayer: localPlayer];
}
else
{
[self disableGameCenter];
}
}];
}
I'm now having trouble defining these methods being called in the authentication method.
My explicit question: How do I authenticate a local player?
I have been developing a game which allows for multiplayer matches. I had previous tested the multiplayer invitations and they had all worked. Sending a request from one device displayed a banner on the other and if the invite was accepted the game started.
Just before submitting the app, two nights ago, I tested this functionality again only to find that it has stopped working.
- (void)authenticateLocalUser:(UIViewController *)viewController :(id<GCHelperDelegate>)theDelegate
{
delegate = theDelegate;
self.presentingViewController = viewController;
if (!gameCenterAvailable) {
// Game Center is not available.
userAuthenticated = FALSE;
}
else{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
/*
The authenticateWithCompletionHandler method is like all completion handler methods and runs a block
of code after completing its task. The difference with this method is that it does not release the
completion handler after calling it. Whenever your application returns to the foreground after
running in the background, Game Kit re-authenticates the user and calls the retained completion
handler. This means the authenticateWithCompletionHandler: method only needs to be called once each
time your application is launched. This is the reason the sample authenticates in the application
delegate's application:didFinishLaunchingWithOptions: method instead of in the view controller's
viewDidLoad method.
Remember this call returns immediately, before the user is authenticated. This is because it uses
Grand Central Dispatch to call the block asynchronously once authentication completes.
*/
//ios 6
[localPlayer setAuthenticateHandler:(^(UIViewController* viewcontroller, NSError *error) {
if (viewcontroller != nil){
userAuthenticated = FALSE;
[self.presentingViewController presentViewController: viewcontroller animated: YES completion:nil];
}
else if (localPlayer.isAuthenticated){
// Enable Game Center Functionality
userAuthenticated = TRUE;
[self checkForInvite:self.presentingViewController :delegate];
if (! self.currentPlayerID || ! [self.currentPlayerID isEqualToString:localPlayer.playerID]) {
// Current playerID has changed. Create/Load a game state around the new user.
self.currentPlayerID = localPlayer.playerID;
// get friends of local player
[localPlayer loadFriendsWithCompletionHandler:^(NSArray *friends, NSError *error) {
if (friends != nil)
{
[self loadPlayerData: friends];
}
}];
}
}
else{
userAuthenticated = FALSE;
}
[scoreHandler setGameCentreAvailable:userAuthenticated];
})];
}
}
- (void)checkForInvite :(UIViewController *)viewController :(id<GCHelperDelegate>)theDelegate
{
delegate = theDelegate;
self.presentingViewController = viewController;
NSLog(#"Invite handler installed");
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
// Insert application-specific code here to clean up any games in progress.
if (acceptedInvite){
NSLog(#"Accepted");
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
mmvc.matchmakerDelegate = self;
[viewController presentViewController: mmvc animated: YES completion:nil];
} else if (playersToInvite) {
NSLog(#"Match Request");
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = playersToInvite;
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;
[viewController presentViewController: mmvc animated: YES completion:nil];
}
};
}
The debug window in xcode shows the following:
2013-03-27 18:06:20.112 MyApp[791:907] Authentication changed: player authenticated.
2013-03-27 18:06:21.219 MyApp[791:907] Invite handler installed

e = 2;
h = A42FD7FD;
}]
Is the "I am []..." significant in the lines above?
I have even downloaded and run the tutorial from Ray Wenderlich's site for creating a multiplayer game and tried that. That exhibits the same issues, unless it is running in the foreground on both devices. My app does not display invitation requests even if running in the foreground.
Has anyone else experienced this problem or have any ideas what is going on? authenticateLocalUser is called from applicationDidFinishLaunching
The only way I could make invites-by-name work is by going to Settings/Notifications/Game Center and making Game Center display Alerts, not Banners.
If you have GC display alerts, you get a popup box like this:
This dialog acts like a big parent. If the user hits Accept, then your [GKMatchmaker sharedMatchmaker].inviteHandler gets invoked.
If the user hits Decline, then your game never knows that he was invited to any party ever. User hitting Decline means the parent rips up the invitation and never tells his child he got invited to a game at all.
This is the only way I could get invite-by-name to work.
As I understand from reading documentation, UIPopoverControllers are only supported on the iPad. Therefore if you try to declare a variable as a UIPopoverController and run the app in the iPhone simulator or on an iPhone, you get an error such as:
UIPopoverController initWithContentViewController:] called when not running under UIUserInterfaceIdiomPad
So I have a universal monotouch app I am trying out, where I would like to use a UIPopoverController when the user is using an iPad, for the iPhone I have another solution.
This is how I am declaring it at the moment, but obviously running on the iPhone does not work, and I get the above error message.
public partial class IOPSCalculatorViewController : UIViewController
{
static bool UserInterfaceIdiomIsPhone {
get { return UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Phone; }
}
static bool UserInterfaceIdiomIsIPAD {
get { return UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Pad; }
}
UIPopoverController DetailViewPopover = new UIPopoverController(new PopoverContentViewController());
}
How can I only declare the:
UIPopoverController DetailViewPopover = new UIPopoverController(new PopoverContentViewController());
part if the device is an iPad? I need the UIPopoverController to be in the public partial class so that I can access it publically in other places.
Instead of declaring and allocating in one line just split it in two lines. E.g.
UIPopoverController DetailViewPopover = null;
if (IOPSCalculatorViewController.UserInterfaceIdiomIsIPAD) {
DetailViewPopover = new UIPopoverController (new PopoverContentViewController ());
}
That will also work if DetailViewPopover is a (public) field instead of an instance variable and, as long as the UIPopoverController constructor is not invoked, you won't be getting the error.
You need to find out what is your current device and write code for iphone and iPad as well. here is a snap of code that I've used in my case.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
//Do your coding here
}
else {
if(![popoverController isPopoverVisible]){
contact = [[[ContactViewController alloc] initWithNibName:#"ContactViewController_iPad" bundle:nil] autorelease];
popoverController = [[[UIPopoverController alloc] initWithContentViewController:contact] retain];
[popoverController setPopoverContentSize:CGSizeMake(400.0f, 400.0f)];
[popoverController presentPopoverFromRect:CGRectMake(230, 860, 320.0f, 320.0f) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
[popoverController release];
}else{
[popoverController dismissPopoverAnimated:YES];
}
}
hope this will help you. Happy Coding!!!
if([MFMessageComposeViewController canSendText])
{
MFMessageComposeViewController *sms_message_vc = [[MFMessageComposeViewController alloc] init];
sms_message_vc.body = text;
sms_message_vc.recipients = recipients;
sms_message_vc.messageComposeDelegate = self;
[self presentModalViewController:sms_message_vc animated:FALSE];
[[UIApplication sharedApplication] setStatusBarHidden:TRUE];
[sms_message_vc release];
}
When this executes there's a delay of several seconds before the compose view is actually shown. What is causing this and how does one go about eliminating the delay?
EDIT 1: Clarification: Making sms_message_vc and ivar doesn't help because the ...alloc] init] process will hang the UI for seconds, regardless of where it is.
EDIT 2: Tried GCD (with different priorities) to attempt to run initialization concurrently. Did not help:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, (unsigned long)NULL), ^(void){
sms_message_vc = [[MFMessageComposeViewController alloc] init];
sms_message_vc.messageComposeDelegate = self;
});
Consider making MFMessageComposeViewController *sms_message_vc a class instance variable and calling:
MFMessageComposeViewController *sms_message_vc = [[MFMessageComposeViewController alloc] init];
earlier, along with setting the delegate to self right after initing sms_message_vc
Then just do:
sms_message_vc.body = text;
sms_message_vc.recipients = recipients;
[self presentModalViewController:sms_message_vc animated:FALSE];
[[UIApplication sharedApplication] setStatusBarHidden:TRUE];
[sms_message_vc release];
When you want to actually send the message. This shouldn't change it too much but might help some.
I have the same problem.
I tried to cache the controller in a static variable. But it did not work. behaved erratically. First time works, second time delegate called automatically without any user action and 3rd time screen goes black. Looks like you have to create the instance after each dismiss!
import Foundation
import UIKit
import MessageUI
class UIUtil {
static var messageController:MFMessageComposeViewController? = nil
static var checkedOnce = false
class func createMessageController () -> MFMessageComposeViewController? {
if checkedOnce {
return messageController
}
checkedOnce = true
if (MFMessageComposeViewController.canSendText()) {
messageController = MFMessageComposeViewController()
messageController?.recipients = [SettingsManager.shared.switchPhoneNumber]
} else {
print("SMS services are not available in this device.")
}
return messageController
}
}
usage,
func createSMSView (text:String) {
print("Sending SMS to \(SettingsManager.shared.switchPhoneNumber). Text: \(text)")
if let ctr = UIUtil.createMessageController() {
ctr.body = text
ctr.messageComposeDelegate = self
self.present(ctr, animated: true, completion: nil)
} else {
print("Could not send SMS. Text: \(text)")
}
}
Hi
I am adding a "post comment section in my iPhone APP"
rest all things are working fine but when I tap on "postController textView" a keyboard is suppose to appear from the bottom but it is not appearing However the cursor is displaying and the text that I am passing using postController.textView.text = #"" is also displaying.
Please suggest the areas to be looked for fixing this bug.
-(void)showCommentView
{
TTPostController *postController = [[TTPostController alloc] init];
// self must implement the TTPostControllerDelegate protocol
postController.delegate = self;
self.popupViewController = postController;
// assuming self to be the current UIViewController
postController.superController = self;
postController.textView.text=#"temporary text";
[postController showInView:self.view animated:YES];
[postController release];
}
above is the code that is giving call to the Three20 PostController
below is the calling method which is unchanged...
-(IBAction)postComment:(id)sender
{
[UserManager instance]authenticateUserAndProceed:self withSelector:#selector(showCommentView)];
}
-(void)showCommentView
{
TTPostController *postController = [[TTPostController alloc] init];
// self must implement the TTPostControllerDelegate protocol
postController.delegate = self;
self.popupViewController = postController;
// assuming self to be the current UIViewController
postController.superController = self;
postController.textView.text=#"temporary text";
[postController showInView:self.view animated:YES];
[postController release];
}
changed method
-(void)authenticateUserAndProceed:(id)parent withSelector:(SEL)selector
{
theParentViewController = parent;
self.theFunctionToCall = selector;
if(userid == nil)
{
GetUserInfoViewController *guivc = [[GetUserInfoViewController alloc] init];
[parent presentModalViewController:guivc animated:YES];
guivc.delegate = self;
[guivc release];
}
else {
//////////////////// below line was replaced///////////
// 2. [theParentViewController performSelector:selector];
// with below code
UIAlertView *alert =[[UIAlertView alloc]initWith Title........
[alert show];
}
}
PROBLEM SUMMARY:
as soon as the user registered, he was not able to the kyboard for the TTPostController
CHANGE SUMMARY:
As soon as the user is registered the call to
[theParentViewController performSelector:selector];
is not sent directly but the call goes to ann alertview which inter calls it.
EFETCS SUMMARY:
the user will see a "you are registered successfully" (kind of) alertview.
tapping OK on which, he will be sent to TTPostController. (this time the keyboard is appearing)
I kept the line# 2 in the AlertViewDelegate method.
I was amazed o see it working just by not calling the line 2 directly.
this worked for me.
I welcome any new and better idea to implement the same
