How to animate UILabel font change?

Question

I'm creating a label with font size 0 and i want to enlarge it and at the same time to make it disappear. One important thing is that i want to adjust the label size and place to the center and the view(it can be iphone or ipad). In my code I have to begin with a big font size, to have other suggestions?

My code:

UILabel* swipeLabel = [[UILabel alloc] initWithFrame:self.view.frame];
[swipeLabel setText:NSLocalizedString(@"Swipe to change", @"Swipe label text")];
[swipeLabel setTextColor:[UIColor whiteColor]];
[swipeLabel setTextAlignment:UITextAlignmentCenter];
[swipeLabel setFont:[UIFont systemFontOfSize:2]];
[swipeLabel setAdjustsFontSizeToFitWidth:YES];
[swipeLabel setBackgroundColor:[UIColor clearColor]];
[swipeLabel setNumberOfLines:1];

[self.view addSubview:swipeLabel];


[UIView animateWithDuration:1.5 delay:0 options:UIViewAnimationOptionAllowAnimatedContent animations:^{
     CGFloat scaleFactor = 10.0f;
     swipeLabel.transform = CGAffineTransformMakeScale(scaleFactor, scaleFactor);
    [swipeLabel setAlpha:0];
 } completion:^(BOOL finished) {

 }];

Thanks!

Answer 1

[UIView beginAnimations:nil context:nil];
label.transform = CGAffineTransformMakeScale(0.5,0.5);
[UIView commitAnimations];

This will make the size of font %50 smaller.
