Hi guys I really need some help, I have been stuck in this part of my game for over a week now and I can't seem to get past this issue, So have look at my code below,

#import "HelloWorldLayer.h"
#import "AppDelegate.h" 

@implementation HelloWorldLayer

+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];

// 'layer' is an autorelease object.
HelloWorldLayer *layer = [HelloWorldLayer node];

// add layer as a child to scene
[scene addChild: layer];

// return the scene
return scene;
}

-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with the "super's" return value
if( (self=[super init]) ) {
    moles = [[NSMutableArray alloc] init];
    winSize = [[CCDirector sharedDirector]winSize];
    CCSprite *mole1 = [CCSprite spriteWithFile:@"lightsabericonblue.png"];


   [self starCreateCurrentLevel:mole1];


}
return self;
}


-(void)starCreateCurrentLevel:(CCSprite *)mole1{
starCountCurrentLevel = 10;
for (int i = 0; i < starCountCurrentLevel;) {

    [moles addObject:mole1];        
    starCountCurrentLevel--;

}

[self schedule:@selector(tryPopMoles:) interval:1];

}


- (void)tryPopMoles:(ccTime)dt {
if(moles.count !=   0){
    for (CCSprite *mole in moles) {
        if (arc4random() % moles.count == 0) {
                    if (mole.numberOfRunningActions == 0) {
                        [self popMole:mole];
                    }
        }
    }


}else if(moles.count == 0){
    NSLog(@"No More Moles To Spawn");
    [self unschedule:@selector(tryPopMoles:)];
}

}

- (void) popMole:(CCSprite *)mole {
mole.position = ccp(150, 150);
[self addChild:mole];  
}



- (void) dealloc
{
[moles release];
moles = nil;
[super dealloc];
}

@end

When I run this code i get the following error, * Assertion failure in -[HelloWorldLayer addChild:z:tag:], /Users/....../libs/cocos2d/CCNode.m:335.

I when i add the child in the init method its fine but I don't want to do that, I want to be able to call the try pop mole which will then call the pop mole based on if there is anymore sprites left in the array, I have a feeling I am missing something or doing something wrong.

UPDATE -

#import "AppDelegate.h"

}

        //CCSprite *sprite = [tempArray objectAtIndex:randomIndex];
        [self popMole:sprite];
        NSLog(@"Enemy Added");
        [tempArray removeObject:sprite];
    }
 if([tempArray count] == 0){
    NSLog(@"No More Moles To Spawn");
    [self unschedule:@selector(tryPopMoles:)];
}


}

- (void) popMole:(CCSprite *)sprite {

winSizeX = winSize.width - sprite.contentSize.width + 25;
winSizeY = winSize.height - 25 - sprite.contentSize.height + 17;

スプライトは 1 回しか作成していませんが、何度か追加しようとしています。(これらはオブジェクトへのポインターであるため、常にまったく同じスプライトを参照していることを忘れないでください。) 同じスプライトの 10 個のバージョンが (異なる位置、スケール、速度などで) 必要な場合は、次を作成する必要があります。スプライト (クリエーター メソッド経由) 10 回。元のコピーを作成することも、その場で作成することもできます。

-(void)starCreateCurrentLevel:(CCSprite *)mole1{
starCountCurrentLevel = 10;
for (int i = 0; i < starCountCurrentLevel;) {

    //[moles addObject:mole1];  
    // ^^ You're adding the same sprite (meaning same pointer reference) again and again.  Try this instead:
    [moles addObject:[CCSprite spriteWithFile:@"lightsabericonblue.png"]];      

    starCountCurrentLevel--;
}

もちろん、今度はメソッドに mol1 を渡す必要はありません。(必要に応じて) spriteFrameName などを渡すことを検討してください。
