UIView Animation Freezes

Question

I'm implementing drag-keyboard dismissal (like in the iPhone Messages app) manually because UIScrollViewKeyboardDismissModeInteractive doesn't seem to work with a text view inside a toolbar above the keyboard.

It works in portraint mode, but in landscape orientation, sometimes when I animate the toolbar (which is actually just a UIView) & keyboard, they freeze. But, they did animate because I checked using breakpoints that the animation code ran and when I tap on the screen where they're supposed to be, I get the correct reactions (like keyboard keys pop up, etc.).

I'm using the old style of animations beginAnimations:context: because this is how to mimic the keyboard animation in iOS 7.

This seems like an iOS SDK bug. How do I fix this?

Perhaps its getting cancelled. Also, you can mimic the keyboard animation using more modern style (ie animation blocks). Also you may want to take a look at this question: http://stackoverflow.com/questions/18930423/uitextview-keyboarddismissmode-bug — EricLeaf, Oct 30 '13 at 16:28

I was sometimes (when the pan velocity was large) using UIViewAnimationCurveLinear instead of the curve from the keyboard notification's userInfo. I took that condition out so that I always use the curve from the keyboard notification's userInfo and things seem to be working fine now.
