Question

So I’m trying to get an image to appear at a specific point. I’ve seen some stuff about drawInRect, but I’m not sure why this code isn’t working with drawAtPoint. Here is what I’m using.

- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed:@"icon.png"];
CGPoint kitty;
kitty.x = 144;
kitty.y = 144;
[image drawAtPoint:(CGPoint)kitty];

I’ve also tried this with cGPointMake and just putting the coordinates right after that. Neither method will display the image, yet neither raises an error message. What am I missing?

Answer 1

To get it to work I needed to make a subclass of UIView and I put this in it:

- (void)drawRect:(CGRect)rect
{
[[UIImage imageNamed:@"icon.png"] drawAtPoint:CGPointMake(curPoint.x,curPoint.y) ];
}

The other thing I was missing was the setNeedsDisplay method, which I used in the ViewController.m file.
