drawRect: being called, only shows the frame not the drawing - objective-c

Question

I have a UIControl subclass where I have drawRect implemented. I am trying to draw a rectangle inside of the drawRect method using a UIBezierPath. All the appropriate methods are being called, nothing is null and the app runs with no issues. The problem is, nothing but the frame is drawn. Meaning, I can see the area of the frame, because it is black, but I cannot see anything that was drawn onto the frame.
Here is what I am doing to instantiate the class:
ZHButton *button =
[[ZHButton alloc] initWithFrame:CGRectMake(100, 200, 100, 50)];
button.buttonType = NSSelectorFromString(LEFT_ROUNDED_CORNER_BUTTON);
[self.view addSubview:button];
Here is the drawRect: method, which calls different methods using a selector:
- (void)drawRect:(CGRect)rect {
UIBezierPath *button = [self performSelector:self.buttonType withObject:nil];
[[UIColor orangeColor] setFill];
[button fill];
}
- (UIBezierPath *)drawButtonWithLeftCornersRounded {
return [UIBezierPath bezierPathWithRoundedRect:self.frame
byRoundingCorners:UIRectCornerTopLeft |
UIRectCornerBottomLeft
cornerRadii:buttonRadii];
}
Everything appears to be working fine, but the UIBezierPath does not get drawn. Also, not sure if using a selector is the best way to do this. Anyone know what is going on with this?

Answer 1

It seems you're not calling the drawButtonWithLeftCornersRounded method. I believe this line is wrong:
[self performSelector:self.buttonType withObject:nil];
But it should be:
[self performSelector:#selector(drawButtonWithLeftCornersRounded) withObject:nil];
Hope this helps!

Answer 2

Solved it. In drawButtonWithLeftCornersRounded bezierPathWithRoundedRect should not be self.frame. This will cause the x and y coordinates to be at the x, y location within the frame, not the view. I changed it the parameter to this:
CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height);
