uilabel slide up animation
===

I want to add animation like https://dl.dropbox.com/u/30736398/countdown.mov
to custom CSLabel class in my iOS app. But didn't know how ((

Any ideas? Maybe you have an tutorial? :3

<code>
    
    #import <UIKit/UIKit.h>
    
    @interface CSLabel : UILabel
    
    -(void)setTextWithAnimation:(NSString *)text;

    @end


     #import "CSLabel.h"

    @implementation CSLabel

    - (id)initWithFrame:(CGRect)frame
    {
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        [self setFont:[UIFont fontWithName:@"Helvetica-Bold" size:26]];
        [self setTextAlignment:UITextAlignmentCenter];
        [self setShadowColor:[UIColor blackColor]];
        [self setShadowOffset:CGSizeMake(0, -2)];
        [self setTextColor:[UIColor whiteColor]];
        [self setBackgroundColor:[UIColor clearColor]];
        [self setText:@"00"];
        
    }
    return self;
}
