At least on iOS 7.0 - recommended (default) font for UIButton is not
bold. It is System 15.0 (family: Helvetica Neue, style: Regular, size:
15.0) in Interface Builder.

Could we call UIFont using Objective-C Runtime
Something like:
id class_UIFont = objc_getClass("UIFont");
SEL sel_labelFontSize = sel_registerName("labelFontSize");
float size = objc_msgSend_fpret(class_UIFont, sel_labelFontSize);
?
Anyway, we are back to the original question: What font to use.
Reading Richard's original request we are still not getting the recommend font
which is bold.
I start to think the answer to get this right in the CSS…

Hi,
CTFontCreateUIFontForLanguage() returns fonts with same sizes for both iOS and
Mac OS X. See table below.
Unfortunately I made a mistake when I wrote 15.0 for
CTFontCreateUIFontForLanguage(kCTFontPushButtonFontType) font size,
unfortunately it is 13.0. Other sizes reported were correct (I have verified it
yet once).

Hi,
Correct me if I'm wrong, to use UIWhatever or NSWhatever we will need
Objective-C (or use the ugly objc_msgSend).
That is more work as we don't have Objective-C in native font code. Besides,
creating a Button requires, usually, a lot more boilerplate code. We will also
have to link to UIKit frameworks, etc.
Now, creating a CTFont using
CTFontCreateUIFontForLanguage(kCTFontPushButtonFontType) would be a very easy
change.
Oldrich, could you please prepare a table with the fontSize for all values on
CTFontUIFontType for MacOSX and iOS ?
Thanks

Let's use UIButton as this seems to match the stack overflow discussion.

I have tried simple app with several controls. Fonts in Interface Builder -
UIButton - System 15.0
UILabel - System 17.0
UITextField - System 14.0
UITextView - System 14.0
Same fontsize - 15.0 has UIButton's label created at runtime.
UIFont class methods for getting system font information return:
+ labelFontSize 17.0
+ buttonFontSize 18.0
+ smallSystemFontSize 12.0
+ systemFontSize 14.0
In fx Java_com_sun_javafx_font_MacFontFinder_getSystemFontSize returns 13.0
We can use different CTFontUIFontType in this method to return something
"better" than 13.0 -
e.g. with kCTFontPushButtonFontType as an argument to
CTFontCreateUIFontForLanguage() it returns 15.0, but we need to decide, what we
want to use as default. Should be our system default the size same as for
UIButton, UILabel or other control?
I was using iPad3 (iOS 7.0, Xcode 5.0).

Just an idea.

The problem is that there are about 3 thousand different fonts on the Mac ;-)
Here we are creating a CTFont. For Mac OS X most native apps probably would be using a
NSFont (cause that is what cocoa controls take). Likewise on iOS I think the
"common" font is UIFont (cause I think that is what UIKIt controls take).
Could anyone fire up Xcode, create a dummy iOS app, create a UIFont and see
what is the size ?

If the OS is reporting the wrong value for the default a classic trick is to
create a dummy control that normally has the font we want and query that.

Hi guys,
The default font for iOS is supposed to be System Bold 15 (according to
http://stackoverflow.com/questions/17325152/what-size-font-is-the-title-in-a-default-uibutton
anyway), and it does look more correct to me. Our code is getting to this
native method in MacFontFinder.c
JNIEXPORT jfloat JNICALL
Java_com_sun_javafx_font_MacFontFinder_getSystemFontSize
(JNIEnv *env, jclass obj)
{
CTFontRef font = CTFontCreateUIFontForLanguage(
kCTFontSystemFontType,
0.0, //get system font with default size
NULL);
jfloat systemFontDefaultSize = (jfloat) CTFontGetSize (font);
CFRelease(font);
return systemFontDefaultSize;
}
However it appears the return value is 13 instead of 15 (and I don't know what the actual
default font family / weight is that we're returning). It is possible the answer coming
from this native API call is "wrong". Any ideas?
Richard
