Custom Font Example iPhone

An example for using custom font in iPhone.

Initially, I have tried with UIFont for using custom font, but it seems not possible.

Documents from apple:
http://developer.apple.com/iphone/library/documentation/GraphicsImaging/Reference/CGFont/Reference/reference.html

Create custom font using CGDataProvider:

NSString *fontPath = [[NSBundle mainBundle] pathForResource:@"CUSTOM_FONT" ofType:@"ttf"];

CGDataProviderRef fontDataProvider = CGDataProviderCreateWithFilename([fontPath UTF8String]); CGFontRef customFont = CGFontCreateWithDataProvider(fontDataProvider);

Use the font:

CGContextSetFont(context, customFont);

CGContextSetFontSize(context, 34.0);

CGContextSetTextDrawingMode(context, kCGTextFill);

CGGlyph textToPrint[[mainString length]];

// Loop through the entire length of the text.

for (int i = 0; i < [mainString length]; ++i) { // Store each letter in a Glyph and subtract the MagicNumber to get appropriate value.

textToPrint[i] = [[mainString uppercaseString] characterAtIndex:i] + 3 - 32;

}

//to understand the MagicNumber, I open the font file using FontForge

//found that the font I am using started from location 32

//after I changed the "Encoding->Reencode" to "Glyph Order"

//I found that the "U+0020 space" started from location 3
