Problems animating labels and textfield (objective-c)

I'm having problems with the animation of labels and textfield. The labels just disappear and the text fields don't do anything. I don't know why, but with buttons i have no problem. Think missing something really stupid. Well here is what a i have tried for labels:

UILabel *label = (UILabel*)[self.view viewWithTag:1];
[UIView animateWithDuration:1 animations:^{label.frame = CGRectMake(0,0,1,1);}];

For text fields:

UITextField *box = (UITextField*)[self.view viewWithTag:1];
[UIView animateWithDuration:1 animations:^{box.frame = CGRectMake(0,0,1,1);}];

What i'm missing?

CGRectMake(0,0,1,1) is going to be a really small box. They're not disappearing, you're shoving it all into one pixel. Try something more reasonable, like CGRectMake(0,0,100,50) and see if that works.

CGRectMake is defined as:

CGRect CGRectMake (
   CGFloat x,
   CGFloat y,
   CGFloat width,
   CGFloat height
);

so you were setting the width and height to 1.

If you just want to move the center without resizing, try this. 

[UIView animateWithDuration:1 animations:^{label.center = CGPointMake(x,y);}];

where x and y are the coordinates of the new center.
