Question

Does anyone know how to create a CGGradient that will fill my view,
my current code is this and it fill the UIView with a red rectangle I want to have a gradient (from black to grey for instance) instead of the rect :

- (void)drawRect:(CGRect)rect {
    CGContextRef context=UIGraphicsGetCurrentContext();
    CGRect r;
    r.origin.x=0.;
    r.origin.y=0.;
    r.size.width=rect.size.width;   
    r.size.height=rect.size.height; 
    CGContextSetRGBFillColor(context, 1., 0., 0., 1.);
    CGContextFillRect (context,r);  
}

In my answer to this question, I provide code for drawing a gloss gradient within a UIView. The colors and drawing positions can be modified from that to form whatever linear gradient you need.
