some CATransition string types do not work

I tested CATransition string types as below

@"suckEffect"
@"spewEffect"
@"genieEffect"
@"unGenieEffect"
@"rippleEffect"
@"twist"
@"tubey"
@"swirl"
@"charminUltra"
@"zoomyIn"
@"zoomyOut"

I found that only @"suckEffect",@"rippleEffect" DO work. All others are replaced by Fade Effect.

Even the effect of type @"suckEffect",@"rippleE开发者_运维知识库ffect", it looks like subtype has no function.

I do not know if what I got is right or not?

Welcome any comment.

Thanks

Kindly use this Effects

CATransition *transition = [CATransition animation];
transition.type = @"suckEffect"; // Change to follow types
//transition.type = kCATransitionPush;
transition.duration = 2.0f;
transition.timingFunction = UIViewAnimationCurveEaseInOut;
[self.view.layer addAnimation:transition forKey:@"transitionViewAnimation"];

• kCATransitionFade
• kCATransitionMoveIn
• kCATransitionPush
• kCATransitionReveal
• @"cameraIris"
• @"cameraIrisHollowOpen"
• @"cameraIrisHollowClose"
• @"cube"
• @"alignedCube"
• @"flip"
• @"alignedFlip"
• @"oglFlip"
• @"rotate"
• @"pageCurl"
• @"pageUnCurl"
• @"rippleEffect"
• @"suckEffect"

These transitions are all undocumented and considered "private". So there simply is no guarantee that they exist or work, and if you use them your app is likely to get rejected by Apple. But for some documentation, see the iPhone dev wiki.
