Damn, this is pretty nice. Add particle effects to UIKit, just like in Cocos2D: create them with UIEffectDesigner, then add them to your project with UIEffectDesignerView. Works for both iOS and Mac. Still in beta, but I haven't found any glitches so far.
It's as easy as:
#import "UIEffectDesignerView.h" ... UIEffectDesignerView* effectView = [UIEffectDesignerView effectWithFile:@"name_of_your_choice.ped"]; [self.view addSubview:effectView];
