CALayer UIImage rendered on top of content instead of below
Hi, I have custom UIView with multiple layers, all custom drawn via delegate. In one layer, I draw an image and on top of that image, I draw bezier paths and rects. Or so I try. For some reason the image is rendered ABOVE what I draw OVER it later. So basically I have this (this is the actual code I reduced it to): [img drawInRect:imgRect blendMode:kCGBlendModeNormal alpha:1.0]; followed by [[UIColor redColor] setFill]; UIRectFill(imgRect); I would expect to see a red rectangle, I get the image. Why? Would someone set me straight, I feel I'm missing something basic.
