iPhone - Convert CTFont to UIFont?

问题

I am trying to convert a CTFont to a UIFont without losing any of the styles and attributes such as:

• Font Name
• Font Size
• Font color
• Underlines
• Bold
• Italic
• etc

回答1:

CTFontRef ctFont = ...;
NSString *fontName = [(NSString *)CTFontCopyName(ctFont, kCTFontPostScriptNameKey) autorelease];
CGFloat fontSize = CTFontGetSize(ctFont);
UIFont *font = [UIFont fontWithName:fontName size:fontSize];

Color and underline are not attributes of the font. Bold and italic are part of the font name.

回答2:

With ARC:

UIFont *uiFont = [UIFont fontWithName:(__bridge NSString *)CTFontCopyPostScriptName(ctFont) size:CTFontGetSize(ctFont)];
