Question

I have a method that draws a one sprite on the screen with the animation effects,
if I call in init this method

if( (self=[super init]) ) {
// ....
[self myMethod];
// .....
}

Then he does it once on my project

When I call by schedule

-(void)schedulMyMethod:(ccTime)dt {
    [self myMethod];
}

if( (self=[super init]) ) {
// ....
[self schedule:@selector(schedulMyMethod:) interval:0.5];
// .....
}

It runs for an unlimited times

I need so that I can call the my method some amount

Answer 1

You mean, you want to have it repeat N times? You’ll need to keep state on times remaining for it to run.

@property (nonatomic, assign) NSInteger timesToRunMyMethod;


- (void)beginRunningMyMethod {

    self.timesToRunMyMethod = 100;   // N==100
    [self myMethod];
}

- (void)myMethod {

    self.timesToRunMyMethod--;
    // do stuff
    if (self.timesToRunMyMethod > 0) {
        // i used native delayed execution, you can replace it with whatever cocos2d offers if you want
        [self performSelector:@selector(myMethod) withObject:nil afterDelay:0.5];
    }
}

And it’s probably wrong to start this on init. Is it a view controller? Then you can use viewDidAppear or willAppear.
