Answer 1

You could use:

+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay 
options:(UIViewAnimationOptions)options animations:(void (^)(void))animations 
completion:(void (^)(BOOL finished))completion

And use the Ease in and Ease out transitions to accelerate and decelerate toward the end.

Note: the blocks based animation is only valid in is 4.0 and later if you want earlier you need to use

+ (void)beginAnimations:(NSString *)animationID context:(void *)context

And its a simple matter of editing the frame of the view.
