Arabic Ttf (Truetype Font) in Uiwebview iOS 4.2.1

Arabic TTF (TrueType font) in UIWebView iOS 4.2.1

Hi
I finally figured it out. You can load almost all (.ttf) fonts, either arabic, english or whatever on iOS 3.2 above. You just need to use the correct text (in terms of unicode), to display it.

Custom Arabic Font is working in iOS7 but not in iOS6

Yes it didn't work in iOS6 and before, this seems it was a bug, there are some tricks you can do, check below SO questions:

Arabic text with custom fonts in iOS

Update:

As of iOS 7, you don't really need to use Core Text to render custom arabic font. You can use UILabel and/or UITextView with NSAttributedString. The results are the same as you get using Core-Text. However, depending on your requirements, using Core Text can still be a better option.

Update:

I've reported this as a bug to Apple, but i'm not sure when they'll add support for Arabic fonts. Currently, there's no easy way to do it. I ended up using the default system font, which is not very good.

Original Message

I did managed to build a Quran application that uses custom arabic font. I used known arabic font(s) with Core Text framework to get the desired results. You can see the results I got in the end by checking the application Quran Presenter for iPad, which is available on the App Store.

Here's some sample code to help you out:

- (CTFontRef)newCustomFontWithName:(NSString *)aFontName
                            ofType:(NSString *)type
                        attributes:(NSDictionary *)attributes {
    NSString *fontPath = [[NSBundle mainBundle] pathForResource:aFontName ofType:type];

    NSData *data = [[NSData alloc] initWithContentsOfFile:fontPath];
    CGDataProviderRef fontProvider = CGDataProviderCreateWithCFData((CFDataRef)data);
    [data release];

    CGFontRef cgFont = CGFontCreateWithDataProvider(fontProvider);
    CGDataProviderRelease(fontProvider);

    CTFontDescriptorRef fontDescriptor = CTFontDescriptorCreateWithAttributes((CFDictionaryRef)attributes);
    CTFontRef font = CTFontCreateWithGraphicsFont(cgFont, 0, NULL, fontDescriptor);
    CFRelease(fontDescriptor);
    CGFontRelease(cgFont);
    return font;
}

- (CATextLayer *)customCATextLayer {
    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [NSNumber numberWithFloat:24.f], (NSString *)kCTFontSizeAttribute,
                                [NSNumber numberWithInt:1], (NSString *)kCTLigatureAttributeName,
                                nil];

    CTFontRef font = [self newCustomFontWithName:@"PDMS_Saleem_QuranFont-signed" 
                                          ofType:@"ttf" 
                                      attributes:attributes];

    CATextLayer *normalTextLayer = [[CATextLayer alloc] init];
    normalTextLayer.font = font;
    normalTextLayer.string = NSLocalizedString(@"Sample", nil);
    normalTextLayer.wrapped = YES;
    normalTextLayer.foregroundColor = [[UIColor blackColor] CGColor];
    normalTextLayer.fontSize = 24.f;
    normalTextLayer.alignmentMode = kCAAlignmentCenter;
    normalTextLayer.frame = CGRectMake(0.f, 10.f, 320.f, 32.f);

    CFRelease(font);
    return [normalTextLayer autorelease];
}

- (void)viewDidLoad {
    [super viewDidLoad];

    CATextLayer *normalTextLayer = [self customCATextLayer];
    [self.customView.layer addSublayer:normalTextLayer];
}

Note that I'm using CATextLayer and CTFontRef. There are a few problems with this approach.
1. You'll have to live with the issues in the selected "custom arabic font".
2. You'll have to use the arabic text that uses the extended characters supported by the font.

HTH.

Porting Arabic font to iOS System

Fonts are complex programs that run on embedded hardware interpreters and font engines (the same way game ROMs run on game hardware or in emulators), and don't just contain the pictures for each letter, but also all the instructions on how to position, combine, and substitute those letters based on what sequence of input it's being told to process.

For almost every font, just copying the glyph outlines is not enough, you also need to make sure that:

1. the original font's glyph ordering is preserved,
2. the GPOS table gets copied over (which determines mark positioning, kerning, etc), and
3. the GSUB table gets copied over (which handles glyph substitution, without which you can't even write Arabic. As an example, you need ـب, ـبـ, بـ or ب depending on context for the same "letter" bā’)

So you generally want to unpack the TTC (which as of OpenType 1.7 can be either truetype or postscript/type2, so that's a thing to remember for the future), then perform the replacements of glyphs (with order-preservation), as well as replacing the GPOS and GSUB tables (using FontForge or TTX) and then pack it back up into the TTC.

How to use Arabic Custom Fonts in objective c

Follow these steps

1.) Drag fonts into your project.

2.) Define your fonts name in your plist. Open plist > right click > add row > type : Fonts provided by application > press + > yourFontName.ttf.

It look like this in info plist

Fonts provided by application  : Array : (2 items)

item 0 : fontNameOne.ttf
item 1 : fontNameTwo.ttf

3.) Either you can check it from storyboard or you can do programmatically.

yourLabel.font=[UIFont fontWithName:@"yourFont" size:16.0f];//do not use .ttf here 

Custom arabic font working in iOS 7 but not in iOS 6 or earlier

Problem solved...

UILabel *arTitle = [[UILabel alloc] initWithFrame:CGRectMake(0, 200, 300, 100)];
arTitle.backgroundColor = [UIColor clearColor];
arTitle.textColor = [UIColor blueColor];
arTitle.textAlignment = NSTextAlignmentCenter;
arTitle.font = [UIFont fontWithName:@"GEDinarOne-Medium" size:16.0];
arTitle.numberOfLines = 0;
arTitle.text = @"واللقب هو عربي مع خط مخصص";

// these two line made effect...    
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:arTitle.text attributes:@{ NSFontAttributeName : [UIFont fontWithName:@"GEDinarOne-Medium" size:16], NSLigatureAttributeName: @2}];

arTitle.attributedText = attributedString;
