I am trying to load an external .ttf font into one of my iOS projects. The font works fine within an emulator, but fails to display on an actual device.
I am using the LLVM GCC 4.2 compiler. In another project, with the Apple LLVM compiler 3.0, the same font works. I do not understand how I can fix it? What are the steps I need to follow with the LLVM GCC 4.2 compiler?
Make sure it's added under 'Targets' -> 'Build Phases' -> 'Copy Bundle Resources'. I had a similar problem and by manually adding it to this list, the font started showing up on the device.
For the Custom font below code help
UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(10, 30, 240, 40)];
[label1 setFont: [UIFont fontWithName: @"Grinched" size:24]];
[label1 setText:@"Grinched Font"];
[[self view] addSubview:label1];
UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(10, 80, 240, 40)];
[label2 setFont: [UIFont fontWithName: @"Energon" size:18]];
[label2 setText:@"Energon Font"];
[[self view] addSubview:label2];
Also u can download sample code and tutorial here.
You have a limited choice regarding fonts, so you have to choose between the fonts available...
This answer is useful as a reference: What fonts do iPhone applications support?
First load the font like below:
(void)loadFont{ // Get the path to our custom font and create a data provider.
NSString *fontPath = [[NSBundle mainBundle] pathForResource:@"mycustomfont" ofType:@"ttf"];
CGDataProviderRef fontDataProvider = CGDataProviderCreateWithFilename([fontPath UTF8String]);
// Create the font with the data provider, then release the data provider. customFont =
CGFontCreateWithDataProvider(fontDataProvider); CGDataProviderRelease(fontDataProvider);
}
Then use them as below:
-(void)drawRect:(CGRect)rect{
[super drawRect:rect]; // Get the context.
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextClearRect(context, rect); // Set the customFont to be the font used to draw.
CGContextSetFont(context, customFont);
// Set how the context draws the font, what color, how big.
CGContextSetTextDrawingMode(context, kCGTextFillStroke); CGContextSetFillColorWithColor(context, self.fontColor.CGColor); UIColor * strokeColor = [UIColor blackColor];
CGContextSetStrokeColorWithColor(context, strokeColor.CGColor); CGContextSetFontSize(context, 48.0f);
// Create an array of Glyph's the size of text that will be drawn.
CGGlyph textToPrint[[self.theText length]];
// Loop through the entire length of the text.
for (int i = 0; i < [self.theText length]; ++i) { // Store each letter in a Glyph and subtract the MagicNumber to get appropriate value.
textToPrint[i] = [[self.theText uppercaseString] characterAtIndex:i] + 3 - 32;
}
CGAffineTransform textTransform = CGAffineTransformMake(1.0, 0.0, 0.0, -1.0, 0.0, 0.0);
CGContextSetTextMatrix(context, textTransform);
CGContextShowGlyphsAtPoint(context, 20, 50, textToPrint, [self.theText length]);
}
There are some cases where you may not able to use some of the internet downloaded font. Here is the reference for the same:
