iPhone - having a Ripple effect on a UIImageView

开发者_运维知识库I am attempting to create a ripple like effect on an imageView when it is touched down on, however I do not understand how to implement OpenGL for windows and porting it to iOS. I have attempted to use http://www.codeproject.com/KB/openGL/dsaqua.aspx as well as cocos2d however I find the latter completely and utterly confusing. Would anyone be willing to give some suggestions or can point me in the right direction?

Many thanks!

If you want a ripple effect on a view you can use it.

    CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:2.0f];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
[animation setType:@"rippleEffect" ];
[myView.layer addAnimation:animation forKey:NULL];

Use below for ripple effect in iPhone

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:(UIViewAnimationTransition) 110 forView:view cache:NO];
[UIView commitAnimations];

For more effects you can check this link :

@Rony's CATransition Ripple in Swift

let animation = CATransition()
animation.delegate = self
animation.duration = 2
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
animation.type = "rippleEffect"
myView.layer.addAnimation(animation, forKey: nil)

(This is my first post, so idk if I'm doing it right :D)

For Swift 3.0

let animation = CATransition()
animation.delegate = self
animation.duration = 5.0
animation.timingFunction = CAMediaTimingFunction(name : kCAMediaTimingFunctionEaseInEaseOut)
animation.type = "rippleEffect"
viewForAnimation.layer.add(animation, forKey: nil)

I have tried above mentioned codes but none work perfectly. Find out following source code. https://github.com/willstepp/gl_image_ripple
