Expansion is not animated correctly

[andepopande]

The expansion is not correctly animated when the threshold is reached.
You can reproduce this in the MailAppDemo.

• Open MailAppDemo
• Swipe first cell from left to right -> "Mark as read" gets visible
• Swipe more and more until the threshold is reched

Expected: the blue button animates to the expanded button

Actual: the blue button does not animate, it is expanded immediately

The unexpansion-animation works as expected. You can check this by swiping a few pixels to the left until the threshold is reached -> the button animates correctly to the smaller size. So the "make button smaller" animation is working, the "make button bigger" animation not.

You can see the issue in code:

The [UIView animateWithDuration: in expandToOffset: is NOT working correctly.
The [UIView animateWithDuration: in endExpansioAnimated: is working correctly.

Fixed in the latest version. Also improved the animation with multiple buttons. Thanks for the bug report.
