I have a method to add an 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?
我有一个添加敌人的方法，我想知道我是如何做到的，所以我运行它一定次数（比如10）。我用cocos2d中的调度程序调用该方法并执行[self addEnemy];需要更多信息？

If the selector you schedule is methodA:
如果您安排的选择器是methodA：
[self schedule:@selector(methodA:) interval:1/60];
then a simple way to do what you are looking for is:
然后一个简单的方法来做你正在寻找的是：
- (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.
如果您愿意，可以在班上使用ivar来跟踪重复次数。
