I want to change my UILabel text or UILabel itself’s size by using UISlider

  • 0

I want to change my UILabel text or UILabel itself’s size by using UISlider, I know it’s something we don’t do it for an normal application. But basically I am trying new and different things to explore Objective -C language and iOS platform.

So far I am able to change colour of a font by UISlider, Which looks really great, So thought of changing it’s size too by UISlider. Below I am posting pictures to clarify my thoughts visually!

While making those images I realised I might have to change size of UILable and Size of font too. Am I right? Is this possible?

    textLabel.font = [UIFont boldSystemFontOfSize:slider.value];    
CGSize newSize = [textLabel.text sizeWithFont:textLabel.font];

    This should make it
    an alternative is to set the fram of the label above the complete size above the textField and set textAlignement = center
