In order to create a Singleton you will need a static instance. 

@implementation CarteManager

static CarteManager *_carteManager = nil;

+(CarteManager*)sharedInstance {
   if (!_carteManager) {
        _carteManager = [[CarteManager alloc] init];
    }

    return _carteManager;
}

// your other codes

@end

And before creating a Singleton, make sure that you really need a Singleton. Please pay special attention to Singleton: How should it be used.

You didn't state your problem. If it's how to make the object a singleton, you can find several possible implementations in the question What does your Objective-C singleton look like?.
