How do I set how many times to run a method? (cocos2d iPhone)

I have a method to add an 开发者_开发知识库enemy, and I want to know how I can make it so I run it a certain number of times (say 10). I call the method with a scheduler in cocos2d and by doing [self addEnemy]; Need any more info?

If the selector you schedule is methodA:

[self schedule:@selector(methodA:) interval:1/60];

then a simple way to do what you are looking for is:

- (void) methodA:(ccTime)adelta {
    static int counter = 10;
    if (--counter >= 0) {
         //-- do your processing
    } else {
        counter = 10; //-- this in case you want to reschedule the method at some later point
        [self unschedule:@selector(methodA:)];
    }
}   

If you prefer it, you could use an ivar in your class to track the number of repetitions.
