Also, this part of the code says that there is potential leak in aFireWork.

“aFireWork = [[FireWorks alloc]init];” in:

- (void)resetFireworks:(NSTimer*)theTimer {

NSLog(@”enter”);

CGRect currentFrame = fWView_.frame;

FireWorks *aFireWork;
aFireWork = [[FireWorks alloc]init];
aFireWork.origin = CGPointMake(arc4random()%((int)currentFrame.size.width), arc4random()%((int)currentFrame.size.height));
[aFireWork generateParticles:100];

[fWView_.fireworks addObject:aFireWork];

if([fWView_.fireworks count]>10) {
FireWorks *firstFireWork = [fWView_.fireworks objectAtIndex:0];
[firstFireWork removeSistem];
[fWView_.fireworks removeObjectAtIndex:0];
}
}
