Fade Transitions

I have a bit of code that i use to transition between views.

if (CGRectIntersectsRect(mainSprite.frame, backTopPathImg.frame)) {
    levelOneViewController * levelOne2 = [[levelOneViewController alloc]initWithNibName:nil bundle:nil];
    [self presentModalViewController:levelOne2 animated:NO];
    [levelOne2 changeSpriteLocationTopPath];

}

This makes a regular transition where it just cuts to the other view. My question is how could i make this a fade transition? As in a long fade through black. Keep in mind i am not using a navigation controller, just #importing the view controller then using the above code. Thanks :)

See modalTransitionStyle property of UIViewController.

Try the following

if (CGRectIntersectsRect(mainSprite.frame, backTopPathImg.frame))
{
    levelOneViewController * levelOne2 = [[levelOneViewController alloc]initWithNibName:nil bundle:nil];
    levelOne2.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self presentModalViewController:levelOne2 animated:YES];
    [levelOne2 changeSpriteLocationTopPath];

}

I would suggest having a UIView with a black background laid over top of your levelOne2 and over time change the opacity of it from 1.0 to 0.0.
