I have this method which will report a score to game center:
- (void)reportScore: (int64_t) forCategory: (NSString*) category
{
GKScore *scoreReporter = [[[GKScore alloc] initWithCategory:category] autorelease];
scoreReporter.value = passedint;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if (error != nil)
{
// handle the reporting error
}
}];
}
Now I have an ibaction to try to call that method but I am not able to figure it out..
- (IBAction)uploadscore {
passedint = [[NSUserDefaults standardUserDefaults] integerForKey:#"Scoreoneplayer"];
NSLog(#"%i", passedint);
[self reportScore:(passedint)forCategory :(NSString *) category];
}
passedint is the int I want to upload to Game Center. If anyone can help, that would be greatly appreciated! :)
This should do it:
[self reportScore: passedint forCategory: #"Put your category here"];
You shouldn't need to provide types in the method call.

ORIGINAL QUESTION:
I am really new to coding and hoping that someone can help me with what I am sure is a very simple problem. I have looked at a lot of other answers regarding this error, but they don't seem to apply to my situation.
The following code is part of a game app I am working on using Xcode, trying to integrate it with a third party system called SKILLZ. I did not write any of the code and am trying to understand it as I proceed with the integration.
I have noted within the code where I am getting the error:
#import "WAppDelegate.h"
#import "WViewController.h"
#import <SkillzSDK-iOS/Skillz.h>
#implementation WAppDelegate
- (void)dealloc
{

[super dealloc];
}

//initialize language engine
[WLanguageEngine sharedInstance];
//initialize game mode engine
[WGameModeEngine sharedInstance];
//initialize RevMob
if (revMobActive) {
[RevMobAds startSessionWithAppID:RevMobAppID];
}
if (revMobActive&&revMobTestingMode) {
[RevMobAds session].testingMode = RevMobAdsTestingModeWithAds;
// or
//[RevMobAds session].testingMode = RevMobAdsTestingModeWithoutAds;
}
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
self.viewController = [[[WViewController alloc] initWithNibName:#"WViewController" bundle:nil] autorelease];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}

[[Skillz skillzInstance] skillzInitForGameId:#"940"

I am getting a second occurrence of this error in a different part of the app code, but am hoping that if I can sort this one out that it will help me to understand the other.
Hoping that this is not off-topic or too specific, and that someone might be able to help.

Perhaps you forgot a declaration or added an extraneous } somewhere
bit of a beginner here and I've been stuck on something all day!
I've got 2 Parse Tables: a User (which works perfectly for logging in etc) and a UserStats that holds variables (in this case the User's Level as the first column)
All I want to do is retrieve the User's current level and display it in a label in Xcode. I've done lots of research but I cannot work out where I've gone wrong.
I'm using this Query in my .m:
- (void) retrieveFromParse {
PFQuery query = [PFQuery queryWithClassName:#"UserStats"];
[query whereKey:#"User" equalTo:[PFUser currentUser]];
[query getFirstObjectInBackgroundWithBlock:(PFObjectobject, NSError *error)
{
if (!object)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Oh No!" message:#"Could not locate value!" delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil];
[alert show];
}
else
{
int Level = [[object objectForKey:#"Level"] intValue];
[_newlabel setText:[NSString stringWithFormat:#"%d", Level]];
}
}];
}
and my .h looks like this:
import <UIKit/UIKit.h>
import <Parse/Parse.h>
#interface ShowLevel : UIViewController
#property (weak, nonatomic) IBOutlet UILabel *newlabel;
#end
Edit: I've turned on exception breakpoints and it's highlighting:
[query getFirstObjectInBackgroundWithBlock:^(PFObject *object, NSError *error) {
What is the actual error that you are getting? Also you have to do anything that has to do with UI on the main thread. The query is actually running on the background thread and you are either showing alertView or updating a label which you have to do on the main thread. Add dispatch_async(dispatch_get_main_queue(), ^{ }); to your code where you are doing UI
if (!object)
{
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Oh No!" message:#"Could not locate value!" delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil];
[alert show];
});
}
else
{
int Level = [[object objectForKey:#"Level"] intValue];
dispatch_async(dispatch_get_main_queue(), ^{
[_newlabel setText:[NSString stringWithFormat:#"%d", Level]];
});
}
This has since been resolved. I used the .m code:
PFQuery *query = [PFQuery queryWithClassName:#"UserStats"];
PFObject *Object = [query getObjectWithId:#"fghsd7fddhf"];
level = [[Object objectForKey:#"Level"] intValue];
[levelLabel setText:[NSString stringWithFormat:#"%i", level]];
While it's only temporary since I'll need to change it to point to values without specifying objectId, this works nicely for testing. Thanks to everyone who provided help :)
I'm coding in Cocoa, on OS X.
I'm trying to receive a file that is dragged and dropped onto my NSView subclass - which I can do; and get its contents and filename and display them - which I can do for any type of file first time, but on the second time, when I try and drag another file on, I can only set the title setTitle:, but not the main body text setText:
The errors I am getting are:
Canceling drag because exception 'NSInternalInconsistencyException' (reason 'Invalid parameter not satisfying: aString != nil') was raised during a dragging session
and
Assertion failure in -[NSTextFieldCell _objectValue:forString:errorDescription:], /SourceCache/AppKit/AppKit-1187/AppKit.subproj/NSCell.m:1532
My code (sorry, it's quite long!):
- (BOOL)performDragOperation:(id<NSDraggingInfo>)sender {
NSPasteboard *pboard;
NSDragOperation sourceDragMask;
sourceDragMask = [sender draggingSourceOperationMask];
pboard = [sender draggingPasteboard];
if ([[pboard types] containsObject:NSFilenamesPboardType]) {
NSURL *file = [NSURL URLFromPasteboard:pboard];
//NSData *data = [NSData dataWithContentsOfURL:file];
NSError *error;
NSStringEncoding encoding;
NSString *contentString = [[NSString alloc] initWithContentsOfURL:file usedEncoding:&encoding error:&error];
NSLog(#"Error: %#",error);
NSString *last = [[file path] lastPathComponent];
NSArray *parts = [last componentsSeparatedByString:#"."];
NSString *filename = [parts objectAtIndex:0];
NSString *fileType = [parts objectAtIndex:1];
NSLog(#"FILETYPE: %#", fileType);
if ([fileType isEqualToString:#"txt"] || [fileType isEqualToString:#"md"]) {
[self setTitle:filename];
if (self.textViewString == (id)[NSNull null] || self.textViewString.length == 0) {
[self setText:contentString];
} else {
BOOL whatToDo = (NSRunCriticalAlertPanel(#"What do you want to do?", nil, #"Append", #"Replace", nil) == NSAlertDefaultReturn);
if (whatToDo) {
//Append
[self setText:[NSString stringWithFormat:#"%#\n%#",self.textViewString,contentString]];
} else {
//Replace
[self setText:contentString];
}
}
return YES;
} else {
return NO;
}
} else if ([[pboard types] containsObject:NSPasteboardTypeString]) {
NSString *draggedString = [pboard stringForType:NSPasteboardTypeString];
if (self.textViewString == (id)[NSNull null] || self.textViewString.length == 0) {
[self setText:draggedString];
} else {
[self setText:[NSString stringWithFormat:#"%#\n%#",self.textViewString,draggedString]];
}
return YES;
}
else {
return NO;
}
}
Thanks in advance! :)
Sounds like Cocoa is canceling the drag when any exception is raised, and an exception is getting raised when something internally is expecting a string and is getting a nil value instead.
It's just a guess without having more information, but I would predict that stringWithFormat: is raising the exception, as it looks like the only really potentially fragile bit of what you have written.
You are doing a couple ill-advised things. First, you are assuming that -initWithContentsOfURL:usedEncoding:error: is succeeding. You should not do this. Instead, you need to pass an NSError ** that can be filled in on error, test whether contentString is nil, and, if so, check the error accordingly. I have a feeling that you will find you are getting nil, and the error will explain why.
Possibly unrelated, but your if (whatToDo) is not doing what you probably think it is. Since whatToDo is a pointer to an autoreleased NSNumber instance your conditional will always evaluate to true, since the pointer is non-zero. What you likely meant to do was something like the following:
BOOL whatToDo = (NSRunCriticalAlertPanel(#"What do you want to do?", nil, #"Append", #"Replace", nil) == NSAlertDefaultReturn);
if (whatToDo) {
//Append
[self setText:[NSString stringWithFormat:#"%#\n%#",self.textViewString,contentString]];
} else {
//Replace
[self setText:contentString];
}
Lots of thanks for the many tips and pieces of advice from this answer by Conrad Shultz! I've followed the advice and tips there.
However, my problem turned out to be very, very basic. It lied in the line BOOL whatToDo = (NSRunCriticalAlertPanel(#"What do you want to do?", nil, #"Append", #"Replace", nil) == NSAlertDefaultReturn);
It turns out a string must be passed to the second parameter, but I was passing nil. Fixed!
I have been working ver hard on Game center. I have tested so many codes I've lost count.
I would love to know how to automatically submit score as well
here are some codes i have used but i am not sure if this will help
-(IBAction)showleaderboard:(id)sender{
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc]init];
if (leaderboardController !=NULL) {
leaderboardController.category = self.currentLeaderboard;
leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
leaderboardController.leaderboardDelegate = self;
[self presentModalViewController:leaderboardController animated:YES];
}
}
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController{
[self dismissModalViewControllerAnimated:YES];
[viewController release];
}
-(IBAction)showAchivementLeaderboard:(id)sender{
GKAchievementViewController *achivements = [[GKAchievementViewController alloc]init];
if (achivements !=NULL) {
achivements.achievementDelegate = self;
[self presentModalViewController:achivements animated:YES];
}
}
-(void)achievementViewControllerDidFinish:(GKAchievementViewController *)viewController{
[self dismissModalViewControllerAnimated:YES];
[viewController release];
}
self.currentLeaderboard= kEasyLeaderboardID;
if ([gameCenterManager isGameCenterAvailible]) {
self.gameCenterManager= [[[GameCenterManager alloc] init] autorelease];
[self.gameCenterManager setDelegate:self];
[self.gameCenterManager authenticateLocalUser];
}else{
UIAlertView *openURLAlert = [[ UIAlertView alloc] initWithTitle:#"Game Center turned off" message:#"You are not connected to game center." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[openURLAlert show];
[openURLAlert release];
}
To report a score you need to use GKScore as follows;
GKScore *scoreReporter = [[GKScore alloc] initWithCategory:self.gameCategory.leaderboardString];
scoreReporter.value = score;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if (error != nil) {
[[KYTGlobals instance] storeScore:score forCategory:self.gameCategory.leaderboardString];
}
}];
The above code allocates and inits a GKScore object using the identifier that you have already set up on game center for the category that you want to report a score for. You update the value for the score and then use reportScoreWithCompletionHandler making sure to test for error so that you can archive the score and report it later.
this is my first app including the gamecenter, and i have a little problem with it.
i implemented some code i found in the net that should work. Everything works fine, except for "done button" :(
.m
#import <GameKit/GameKit.h>
- (void)viewDidLoad {
[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
if (error == nil)
NSLog(#"Authentication Successful!");
else
NSLog(#"Authentication Failed!");
}];
-(IBAction)subscore{
GKScore *scoreReporter = [[GKScore alloc] initWithCategory:#"lrhseasy"];
scoreReporter.value = score;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if (error != nil) {
NSLog(#"Submitting a score failed!");
}
else {
NSLog(#"Submitting succeeded!");
}
}];
}
-(IBAction)showLeader{
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc]init];
if (leaderboardController != nil) {
//leaderboardController.leaderboardDelegate = self;
[self presentModalViewController:leaderboardController animated:YES];
}
}
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController {
NSLog(#"Close leaderboard");
[self dismissModalViewControllerAnimated:YES];
[viewController.view.superview removeFromSuperview];
}
The last function isn´t called, when the done button is pressed - i don´t get "close leaderboard" in the debug console.
After searching for 3 hours, the only thing i found was
"Did you add GKLeaderboardViewControllerDelegate to the list of protocols that this class implements? " but i do not know what this means or how its done :(
I am having a similar problem but to add GKLeaderBoardViewControllerDelegate to your protocol list do this:
#interface YourClass: NSObject <GKLeaderBoardViewControllerDelegate> {
}
#end
