Question

// Begin Animation "suckEffect".
CATransition* animation  = [CATransition animation];
animation.type           = @"suckEffect";
animation.duration       = 1.0f;
animation.timingFunction =  UIViewAnimationCurveEaseInOut;
myView.opaque            = 1.0f;
[myView.layer addAnimation:animation forKey:@"transitionViewAnimation"];

How you can see I write a part of code witch make an animated when I press delete button. When I press delete button in my application the “suckEffect” take place. But it goes to left corner of the screen. I want to ask you if anybody know how can I do this effect but for left corner of my iphone screen !!!

Answer 1

You can use the undocumented +[UIView setAnimationPosition:]. Beware that the suckEffect is undocumented and Apple will reject apps using it. Same for setAnimationPosition:.
