How to create a custom circled UIView with two different colors?

Question

Is there a way to create a circled UIView with two different colors, like this:

The circle should be divided as you can see on the image (border).

Answer 1

Subclass UIView and implement the drawRect: method.

Here is code to draw a circle to get you started:

- (void)drawRect:(CGRect)rect
{
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGContextAddEllipseInRect(ctx, rect);
    CGContextSetFillColor(ctx, CGColorGetComponents([[UIColor blueColor] CGColor]));
    CGContextFillPath(ctx);
}
