Change font size with UISlider

Question

Hi, I am trying to change the font size of my UITextView using the value from a UISlider. i need some tips or sample code :) thank you .

Answer 1

1. Create a UISlider.

2. Add your view controller as a target for UISlider's value changed event, i.e.:

   [slider addTarget:self action:@selector(sliderActionHandler:)
    forControlEvents:UIControlEventValueChanged];
   

3. Change the font size inside this handler.
