Temporary release memory

I am creating a quiz app in iPhone.

So that i have so many labels and buttons in use at a time.

If i release them right after one question then application stops.

If i am not doing that and releasing them at dealloc function then it shows memory warning and app crashes. I am using this Code

received memory warning. level 1

If i set around 20 questions then application is not crashing but if i add more questions then it crashes..

I think it is allocating memory and not releasing right after one question.

Please help me out this:(

Edited :

I am using this code after selecting answer

-(void)checkAnswer:(int)theAnswerValue
{   
[AVback stop];
[scrollview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO]; 
[Challengetext setHidden:YES];
[theScore setHidden:YES];
[theQuestion setHidden:NO];
[Question setHidden:YES];  
if(rightAnswer == theAnswerValue)
{
    NSString *AVpath = [[NSBundle mainBundle] pathForResource:@"Winner_1" ofType:@"m4a"];
    AVAudioPlayer *AVbtn1 = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:AVpath] error:NULL];


    [img1 setHidden:NO];
    [img2 setHidden:YES];
    [theQuestion setFont:[UIFont fontWithName:@"Futura" size:30]];
    theQuestion.textColor = [UIColor purpleColor];
    theQuestion.text = @"\n\nCorrect Answer!!";
    [rightans setHidden:NO];
    [Description setHidden:NO];
    [ContainerView setHidden:NO];
    myScore = myScore + 50;
}
else
{

    NSString *AVpath = [[NSBundle mainBundle] pathForResource:@"incorrect2" ofType:@"m4a"];
    AVAudioPlayer *AVbtn1 = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:AVpath] error:NULL];
    QuizAppUniversalAppDelegate *appDelegate = (QuizAppUniversalAppDelegate *) [[UIApplication sharedApplication] delegate];
    if(appDelegate.soundIndicator == 0){
        [AVbtn1 play];

    }
    else{
        [AVback stop];
        [AVstart stop];
        [AVbtn1 stop];
    }

    [img2 setHidden:NO];
    [img1 setHidden:YES];
    [theQuestion setFont:[UIFont fontWithName:@"Futura" size:30]];
    theQuestion.textColor = [UIColor redColor];
    theQuestion.text = @"\nIncorrect Answer!!\nRight answer is : \n ";
    [rightans setHidden:NO]; 
    [Des开发者_JAVA技巧cription setHidden:NO];
    [ContainerView setHidden:NO];
    myScore = myScore ;

}

Thanks.. Any help will be appreciated.. !!

You don't appear to be releasing your avBtn1 object anywhere, and you are allocating a new one every time checkAnswer is called. Is that dealt with somewhere else in the code?
