What size font is the title in a default UIButton?

Question

What is the default font size in a UIButton?

I checked Apple's documentation but I could not find it - https://developer.apple.com/documentation/uikit/uibutton

Answer 1

Its System Bold 15.0. You can check it here.

And you can change font using this code.

[myButton.titleLabel setFont:[UIFont fontWithName:@"Helvetica-Bold" size:13.0]];

Answer 2

You can see it in the Interface Builder when you create a button, is:

System Bold 15.0

Answer 3

Just by having a look at the Storyboard editor in Xcode, selecting a Round Rect Button, you can see in the Attributes Inspector that the font is "System Bold" with size 15 (pt).
