How to change the uitextview font size

Question

can any one help to change the font size in UITextView.

[textView setFont:[UIFont fontWithName:@"ArialMT" size:30]]; 

I use this one but it doesn't work.

Answer 1

Have you bind textView with xib or allocated textView?

If yes,

You can use following code to check whether this works

[textView setFont:[UIFont boldSystemFontOfSize:15]]; 

or

 [textView setFont:[UIFont systemFontOfSize:15]]; 

Answer 2

Check, if "Selectable" is checked in the xib/Storyboard attribute inspector. If it's not selectable, the size wont be changed
