Cocoa应用程序中的自定义字体

Question

I know you can customize fonts by using Interface Builder and selecting a font. However, I'm curious if I can use a custom font that's not included by default on systems. Is there a way to include a custom font in my application?

Answer 1

While the manual font activation procedure is one option, you might also consider the ATSApplicationFontsPath Info.plist key:

Information Property List Key Reference :

" ATSApplicationFontsPath ( String - Mac OS X) identifies the location of a font file or directory of fonts in the bundle's Resources directory. If present, Mac OS X activates the fonts at the specified path for use by the bundled application. The fonts are activated only for the bundled application and not for the system as a whole. The path itself should be specified as a relative directory of the bundle's Resources directory. For example, if a directory of fonts was at the path /Applications/MyApp.app/Contents/Resources/Stuff/MyFonts/ , you should specify the string Stuff/MyFonts/ for the value of this key."

I'd be sure to double-check, but I believe this functionality was added in OS X 10.5.x (which the code posted by Jinhyung Park targets).

ATSApplicationFontsPath uses [NSBundle mainbundle] path as base path, so it does not work when Resources folder is not located there (eg for app plugins).

In my Cocoa plugin I need to load custom fonts using CTFontManagerRegisterFontsForURL

#import <Cocoa/Cocoa.h>

static void FGDActivateFont(NSString *fontName)
{

    // Can't make ATSApplicationFontsPath in Info.plist work for plugins (non-standard Resources path)

    NSArray *availableFonts = [[NSFontManager sharedFontManager] availableFonts];

    if (![availableFonts containsObject:fontName]) {

        NSURL *fontURL = [[FGDRapidCart bundle] URLForResource:fontName withExtension:@"ttf" subdirectory:@"Fonts"];
        assert(fontURL);
        CFErrorRef error = NULL;
        if (!CTFontManagerRegisterFontsForURL((__bridge CFURLRef)fontURL, kCTFontManagerScopeProcess, &error))
        {
            CFShow(error);
        }

    }

}

int main(int argc, char *argv[])
{
    @autoreleasepool
    {
        FGDActivateFont(@“FontAwesome”);
    }
    return NSApplicationMain(argc, (const char **)argv);
}

Here is the example for Mac App custom font loading.

NSString *fontFilePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"/fonts"];
fontsURL = [NSURL fileURLWithPath:fontFilePath];
if(fontsURL != nil)
{
    OSStatus status;
    FSRef fsRef;
    CFURLGetFSRef((CFURLRef)fontsURL, &fsRef);
    status = ATSFontActivateFromFileReference(&fsRef, kATSFontContextLocal, kATSFontFormatUnspecified, 
                                              NULL, kATSOptionFlagsDefault, NULL);
    if (status != noErr)
    {
        errorMessage = @"Failed to acivate fonts!";
        goto error;
    }
}

I have managed to do this using cocos2d (CCLabelBMFont) and hiero tool. You will need to create the font using the hiero, and give this font to the CCLabelBMFont object.
