iOS 5 Openflow Tweaks
Openflow is an open source library that implements an iTunes style cover flow. [http://apparentlogic.com/openflow/]
When iOS5 was released, though, it started looking funny – the covers were coming in from the front instead of the back. The perspective was completely off.
This can be fixed with a few tweaks outlined at http://stackoverflow.com/questions/7686506/how-can-i-make-openflow-work-correctly-in-ios-5-0
Specifically the following
|
1 2 3 4 |
leftTransform = CATransform3DIdentity;
leftTransform = CATransform3DRotate(leftTransform, SIDE_COVER_ANGLE, 0.0f, 1.0f, 0.0f);
rightTransform = CATransform3DIdentity;
rightTransform = CATransform3DRotate(rightTransform, SIDE_COVER_ANGLE, 0.0f, -1.0f, 0.0f); |
Turns into

1 2 3 4 |
leftTransform = CATransform3DTranslate(CATransform3DIdentity, 0, 0, SIDE_COVER_ZPOSITION);
leftTransform = CATransform3DRotate(leftTransform, SIDE_COVER_ANGLE, 0.0f, 1.0f, 0.0f);
rightTransform = CATransform3DTranslate(CATransform3DIdentity, 0, 0, SIDE_COVER_ZPOSITION);
rightTransform = CATransform3DRotate(rightTransform, SIDE_COVER_ANGLE, 0.0f, -1.0f, 0.0f); |
