iOS set text color in a view's drawrect

Question

I have code that does custom rendering inside of a drawRect method in a UIView subclass. I am trying to render text out using [NSString drawInRect] which works great, however it always shows up in white. After much googling and browsing SO I have no been able to find out how to change the color of a text. Any advice would be great.

Edit Below is the snippet of code inside my drawRect implementation

if(self.state != UIControlStateHighlighted)
{
    CGContextSaveGState(context);
    CGContextSetFillColorWithColor(context, color);
    CGContextSetShadowWithColor(context, CGSizeMake(0, 2), 3.0, shadowColor);
    CGContextAddPath(context, path);
    CGContextFillPath(context);
    [title drawInRect:rect withFont:[UIFont fontWithName:@"Helvetica-Bold" size:20]];
    CGContextRestoreGState(context);
}

I assume the `context` here was retrieved with `UIGraphicsGetCurrentContext()`? — Lily Ballard, Feb 29 '12 at 20:09
BTW, `state` is actually a bitfield. You should be testing `if ((self.state & UIControlStateHighlighted) == 0)` — Lily Ballard, Feb 29 '12 at 20:11
That is correct. The view renders properly with everything I pass to the context, it's just the text doesn't change it's color. — Seb, Feb 29 '12 at 20:12
Just for kicks, what if, before the `-drawInRect:`, you try `[[UIColor colorWithCGColor:color] set];`? — Lily Ballard, Feb 29 '12 at 20:14
Where exactly would I call that? Since I don't actually call the method. — Seb, Feb 29 '12 at 20:22
That did the trick. Why would this work and not individually calling 'setFill' or 'setStroke'? — Seb, Feb 29 '12 at 20:36

Before drawing text, you have to set the color. Try this,

[[UIColor blackColor] set]; 
[title drawInRect:rect withFont:[UIFont fontWithName:@"Helvetica-Bold" size:20]];

Have you tried changing the current fill color?

[[UIColor redColor] setFill];
[string drawInRect:rect withFont:font];

I've tried setting the fill and the stroke to various colors and still all I get is white text. – Seb Feb 29 '12 at 19:57
