Question

wat i am trying to is, each time user touches screen, i am adding a small bulletr image on screen

UIImage *img = [UIImage imageNamed:@"shoot_a.png"]; //bullet shot image
        im.image = img;
[self.view addSubview:im];

, if user touches 50 times, there will be 50 images on screen.

now i want, if user hit a button, all these bullet should be remove from the screen.

i hope i am clear about my question.

[im removefromsuperview] doesnt work for me.

if i want to add images to array at run time, how can i add and release?
or is there any better way to clear all images
regards.

this is my touch method, i m adding bullet images on screen frm heere,, but these images are not getting added in Array

// Touch method
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    if(restrictTap == YES){



    NSUInteger numTaps = [[touches anyObject] tapCount];
    NSString *numTapsMessage = [[NSString alloc] initWithFormat:@"%i", numTaps];
        [numTapsMessage release];
    // getting location
    CGPoint touchLocation = [[touches anyObject] locationInView:self.view];
    NSString *locationMessage = [[NSString alloc] initWithFormat:@"Location: X = %.0f Y = %.0f", touchLocation.x, touchLocation.y];
        //bullet shot  image
        im = [[UIImageView alloc] initWithFrame:CGRectMake(self.location.x, self.location.y, 12.0, 12.0)];

        float j =self.location.x;
        float i =self.location.y;

        img = [UIImage imageNamed:@"shoot_a.png"]; //bullet shot image
        im.image = img;
         //im.hidden = NO;
        [self.view addSubview:im]; ///bullet shot image is over transparent view            

        [imageArray addObject:img];



}
}

You could keep track of them via a NSMutableArray property and use that to remove them:

// create e.g. in initializer:
imageArray = [[NSMutableArray alloc] init];

// clean-up, e.g. in dealloc:
self.imageArray = nil;

// add image:
[imageArray addObject:im];

// remove all:
for (UIView *img in imageArray) {
    [img removeFromSuperview];
}
[imageArray removeAllObjects];
