When increasing the height of label, everything is fine and smooth. When decreaseing, the label is instantly changing the size then repositioning with animation.

@interface
@property (nonatomic, retain) IBOutlet UILabel *explanationLabel;

@implementation
CGRect frmExpl = explanationLabel.frame;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.75];

frmExpl.size.height -= height;
explanationLabel.frame = frmExpl;

[UIView commitAnimations];

I've tried replacing UILabel with UIView and of course there is no such problem with UIView.

Is there any special way to animate UILabel size decrease?

Here is a minimal project demonstrating the issue described. Download
