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]];

This works, but it is really strange that font changing in storyboard has no effect. – Stan Nov 19 '13 at 16:54

@iMOBDEV I'd add the swift case also, it helped to me ;): textView.font = UIFont.systemFontOfSize(16.0) – Nicholas Feb 10 '15 at 20:44

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

Please fix this Apple. Making something selectable shouldn't make the font and text justification propagate. – Joe Andolina Oct 09 '14 at 01:36

Well.. if you use the answer above (@iMOBDEV), then you can leave the Selectable unchecked and it will change the font size while not allowing the user to select the text. – StinkyCat Dec 31 '14 at 16:30

This seems to be fixed in iOS 10. I had such a hard time figuring out why this was different in iOS 9. Thanks! – Yngve Hammersland Dec 07 '16 at 20:48

   UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
   [textView  setFont: [UIFont fontWithName:@"ArialMT" size:30]];
   textView.text = @"test my font size";
   [self.view addSubview:textView];
   [textView release];

Your code is correct. The problem is from other part of your code. Provide more details about your textView

Set custom font and size in Swift:

textView.font = UIFont(name: "ArialMT", size: 20)

Use this:

UITextView *myTextView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];  
myTextView.font = [UIFont fontWithName:@"arial" size:14];

I tried it the same way like you with

[textView setFont:[UIFont fontWithName:kFontName size:kFontSize]];

I set the UITextView inside ViewDidLoad. My problem was, I transformed my view:

[_viewEnd setTransform:CGAffineTransformMakeScale(0.0, 0.0)];

My problem was solved with setting the properties of the UITextView after transforming my UIView which includes the UITextView.
