How do you change the color of a UIFont?

Question

I've searched the web and I can't get a good answer, although I'm sure this is very simple. Can someone please show me how to do the following: Make a UIFont of name "Helvetica-Bold", size 8.0, and color of black.

I've got the name and size, but I can't figure out how to change the color:

UIFont *textFont = [UIFont fontWithName:@"Helvetica-Bold" size:8.0];

Thanks!

Solution 1

UIFont does not contain/maintain any color information, so this is not possible. In general, controls that use UIFont such as a UILabel have both a font and a textColor property. So you would set a label's font and it's color like this:

myLabel.textColor = [UIColor blackColor];
myLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:8.0];

Solution 2

If you are drawing text you can use following function;

[text drawAtPoint:CGPointMake(x, y) withAttributes:@{ NSFontAttributeName: [UIFont systemFontOfSize:sizeOfFont], NSForegroundColorAttributeName:[UIColor redColor] }];

Solution 3

If by any chance you're rendering the font to a texture in OpenGL, you can also use the CGContext* functions,

Assuming you already have a valid cgcontext:

CGContextSelectFont(cgContext, "Arial", 24, kCGEncodingMacRoman);
CGContextSetRGBStrokeColor(cgContext, 1.0f, 1, 1, .5f) ;
CGContextShowTextAtPoint(cgContext, 20, 20, "HI THERE", strlen("HI THERE") ) ;

Solution 4

You can also use [myLabel setTextColor:[UIColor grayColor]];.

I think it works. I just did this in swift to get an alternating font colour for a UILabel: commandCount += 1 label.textColor = [.white, .black][commandCount % 2]

Note that CGContextSelectFont is deprecated now, use the CoreText API instead.
