[Game Center] How to post a score to the Game Center? Here is is!

For using game center, your app should be on the Itunesconnect and enable Game Cener.

If you did that, here is what you have to do now.

It is very simple. Try the following codes.

GKScore* score = [[[GKScore alloc] initWithCategory:@"game category name"]autorelease];

            score.value = totalTime*100;

            

            [score reportScoreWithCompletionHandler:^(NSError* error)

             {

                 if(error != NULL)

                 {

                 }

             }];

It it very easy to post your score but... not much players want to even create account on GameCenter;;

I myself in My App am using both GameCenter and Cocoslive leader boards.

Result?

2000 people in cocoslive leader board.

and 

2 people in GameCenter leader board including me.


Have a good day~ :p

[IPhone Dev] NSMutableArray Bad Access -while NSMutableArray reading

nonatomic


That's the one we have to know.


Im not describe what it is because that is not you wanna know :p


So i just get to the point.


if you get bad access error when you read a NSMutableArray, you may wanna use the array in @property way.


make it as a property then use like this


self.dotArray

@property (nonatomic, retain) NSMutableArray *dotArray;

[IPhone Dev] CGPoint in NSMutableArray

Cannot use NSMutableArray with CGPoint.


In .net we use like this


List<CGPoint> list;


but since we don't have that in objective-c, we use this.

NSMutableArray * pointArray = [NSMutableArray array];

        
[pointArray addObject:[NSValue valueWithCGPoint:location]];

[pointArray addObject:[NSValue valueWithCGPoint:lastPoint]];

        

CGPoint retrievedPoint = [[pointArray objectAtIndex:0] CGPointValue];

 
no more words to say.

[IPhone Dev]"This game is not recognized by Game Center" Problem

Straight to the point.

When get "This game is not recognized by Game Center" alert view when you are trying to add Game Center in you app on the device

but works on the simulator, well you are in no problem.

Just remove your app from the device and run on the device again.

It will work. Just got the problem and solved this problem after looked at this thread.

Thanks to Paul.

and now small talk :p

i used cocos2d and cocoslive for my game.

But i decided to go for Game Center. 

I haven't tried the "Campaign" from the admob site but i will try it layer.

Anyway looks like somehow they promote itself by "friends thing".

So.. i will update it with Game Center and see how it goes :p

Good day guys~
