UILabel text scaling, Programmatically?

Question

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!

From -----> To ------->

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?

Answer 1

its quite simple actually

According to slider change value dynamically increase height and width of your label..

Answer 2

有许多方法可以解决此问题，一种方法是仅使用滑块更改字体大小，然后在更改字体时使用sizeWithFont：NSString的实例方法计算帧大小。

Answer 3

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
