xcode iphone particles without cocos2D

is it possible to have particles without using cocos 2D. I know particle designer but we ha开发者_如何学JAVAve to use it with cocos 2D. How can I make particles without cocos 2D ??

You can do it by spawning an image and adding it to an array, which makes it extremly easy to animate the image or do whatever with it.

    - (void)createImage {

    UIImageView *Image = [[UIImageView alloc] initWithFrame:CGRectMake(arc4random() % 320, 480, 40, 40)];
    [Image setBackgroundColor:[UIColor blackColor]];
    [self.view addSubview:Image];
    [myArray addObject:Image];

}

That creates a black image wherever and adds it to an array.

Then, you can make a timer and spawn the image every second!

spawn = [NSTimer scheduledTimerWithTimeInterval:1.0/3 target:self selector:@selector(Spawn) userInfo:nil repeats:YES];


- (void)Spawn {

    [self createImage];

}

You want to go right to 71Squared. He provides videos of creating a very cool particle engine without Cocos2d. Then, once you have your particle emitter workin, you can go ahead and create a simple class to store the particle sets if you want - I did this for my app.
