What is the relationship of a UIView's layer (and its sublayers) to what
happens when that UIView's drawRect: is called? I would expect the code below
to draw a diagonal line across (i.e. on top of) the image, but it looks like
the line is drawn behind the image. In other words, all I see is the image.
@implementation MyView
- (void)awakeFromNib {
CALayer *imgLayer = [CALayer layer];
imgLayer.position = CGPointMake(self.bounds.size.width / 2,
self.bounds.size.height / 2);
imgLayer.bounds = self.bounds;
imgLayer.contents = (id)[[UIImage imageNamed: @"myimage.jpg"] CGImage];
[self.layer addSublayer: imgLayer];
}
- (void)drawRect: (CGRect)rect {
CGMutablePathRef path = CGPathCreateMutable();
CGPathMoveToPoint(path, NULL, 0, 0);
CGPathAddLineToPoint(path, NULL, self.bounds.size.width,
self.bounds.size.height);
CGContextRef context = UIGraphicsGetCurrentContext();
UIColor *black = [UIColor colorWithRed: 0 green: 0 blue: 0 alpha: 0.5];
CGContextSetStrokeColorWithColor(context, black.CGColor);
CGContextSetLineWidth(context, 10);
CGContextSetLineCap(context, kCGLineCapRound);
CGContextAddPath(context, path);
CGContextStrokePath(context);
CFRelease(path);
}
@end
Any hints?
Thanks,
David
