Question

I wish to re-size button at the place where it`s located and delay it, can you please help me?
(sender=UIButton)

My function:

-(IBAction)Animate: (id) sender
{

[sender setBackgroundImage:[UIImage imageNamed:@"Text Bg large.png"] forState:UIControlStateNormal];
CABasicAnimation *scale;
scale = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
scale.fromValue = [NSNumber numberWithFloat:1];
scale.toValue = [NSNumber numberWithFloat:1.3];
scale.duration = 1;
scale.removedOnCompletion = NO;

scale.repeatCount = 1;
[sender addAnimation:scale forKey:@""];
[sender setFrame:(CGRectMake(x, y, z, w))];


}

What do i use for x,y,z,w if i wish that button will stay at the same location, and grow 1.3 time larger without entering values manually. Oh, and how i can delay the this operation?

Answer 1

Is there any reason you’re using CAAnimation to do this?

How about:

CGRect newFrame = CGRectInset(sender.frame, CGRectGetWidth(sender.frame) * -0.15, CGRectGetHeight(sender.frame) * -0.15);

[UIView animateWithDuration: 1.0
                      delay: 0.5
                    options: UIViewAnimationOptionCurveLinear
                 animations:^{
                     [sender setFrame: newFrame];
                 }
                 completion: nil];

or

[UIView animateWithDuration: 1.0
                      delay: 0.5
                    options: UIViewAnimationOptionCurveLinear
                 animations:^{
                     [sender setTransform: CGAffineTransformMakeScale(1.3, 1.3)];
                 }
                 completion: nil];
