Question

How do we go about animating the UILabel‘s width so that it increases and decreases in width only using UIView animateWithDuration

Thank you for your help (at this point i’m so frustrated as I’ve been trying to do so but it does not work)

I was able to do it in this way. self refers to the view in which i’m adding the label. in the init, add the label with width as 1 px. then use the below.. the UIViewAnimationOptionBeginFromCurrentState allows it to be opened like a door PHEW!

    [UIView animateWithDuration:1. delay:0 options:UIViewAnimationOptionBeginFromCurrentState  animations:^{
        [self setFrame:CGRectMake(self.frame.origin.x-labelSize.width-PADDING, self.frame.origin.y, self.frame.size.width+labelSize.width+PADDING, self.frame.size.height)];
        [self.messageLabel setFrame:CGRectMake(95, 10, labelSize.width, labelSize.height)];
        self.messageLabel.alpha = 1; 
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:1. delay:2. options:0  animations:^{
            self.messageLabel.alpha = 0;  
        } completion:^(BOOL finished) {
            [UIView animateWithDuration:1. delay:0. options:0  animations:^{
                [self setFrame:CGRectMake(self.frame.origin.x+labelSize.width+PADDING, self.frame.origin.y, self.frame.size.width-labelSize.width-PADDING, self.frame.size.height)];
            } completion:^(BOOL finished) {
            }];
        }];
    }];
