In my application I want to use the ttf in the documents directory. By referring to the link I use below code to use the font from CGFontRef

+ (UIFont *)loadFontAtPath:(NSString*)path{
NSData *data = [[NSFileManager defaultManager] contentsAtPath:path];


// path is "/Users/............./Documents/bloktilt.ttf"
    if(data == nil){
        NSLog(@"Failed to load font. Data at path is null");
        return nil;
    }
    CFErrorRef error;
    CGDataProviderRef provider = CGDataProviderCreateWithCFData((CFDataRef)data);
    CGFontRef font = CGFontCreateWithDataProvider(provider);

NSString *fontName = (NSString *)CGFontCopyPostScriptName(font);
UIFont *font1 = [UIFont fontWithName:fontName size:15];

if(!CTFontManagerRegisterGraphicsFont(font, &error)){
    CFStringRef errorDescription = CFErrorCopyDescription(error);
    NSLog(@"Failed to load font: %@", errorDescription);
    CFRelease(errorDescription);
}
CFRelease(font);
CFRelease(provider);
return font1;

}

But the problem is that the above code is returning nil

??? Is this for iOS? It looks like OS X (the first line). – borrrden May 24 '13 at 06:06
Regardless, these types are not tollfree bridged (as far as I know). Use this method -> http://stackoverflow.com/a/6714885/1155387 – borrrden May 24 '13 at 06:07
@borrrden But the above code is able to load the ttf file.Is there any other ways of retrieving the font from documents directory – vignesh kumar May 24 '13 at 06:25
Yes, use the accepted way on iOS (Just google iOS documents directory and you will find so many results) – borrrden May 24 '13 at 06:57
@borrrden I've changed my question and find some other way of loading the font But Once again get stopped with the problem of tollfree bridging ie. I can't change the CGFontRef to UIFont. I explained it in the question – vignesh kumar May 24 '13 at 07:01
You have to register it BEFORE you try to make the UIFont – borrrden May 24 '13 at 07:05
@borrrden That one is constraint for me I want to achieve it at the runtime and not before the runtime as registering has to be done manually before compiling the code – vignesh kumar May 24 '13 at 07:10
I'm talking about this -> CTFontManagerRegisterGraphicsFont – borrrden May 24 '13 at 07:13
@borrrden thanks for your guidance I finally get this – vignesh kumar May 24 '13 at 07:23
@borrrden whether CTFontManagerRegisterGraphicsFont will register the font permanently to the device – vignesh kumar May 24 '13 at 08:37
Not sure but I don't think so – borrrden May 24 '13 at 08:40
@borrrden that font lives up to the application instance's life time. – vignesh kumar May 24 '13 at 09:15

@Ankur Yes I have downloaded them through code – vignesh kumar Aug 20 '13 at 14:38
