Maybe it's because it's late. Whatever the reason I can't figure out why I'm having trouble with a simple CSScrollLayer example I'm trying. I add a 50 pixel Eclipse icon to a view based project and in my initialize method (called from initWithNibName:bundle:) I have this:
-(void) initialize
{
CAScrollLayer *scrollLayer = [CAScrollLayer layer];
scrollLayer.backgroundColor = [[UIColor blackColor] CGColor];
CGRect bounds = self.view.bounds;
scrollLayer.bounds = CGRectMake(0, 0, bounds.size.width, bounds.size.height);
scrollLayer.contentsRect = CGRectMake(0, 0, bounds.size.width + 800, bounds.size.height + 800);
scrollLayer.borderWidth = 2.5;
scrollLayer.borderColor = [[UIColor redColor] CGColor];
scrollLayer.position = CGPointMake(self.view.center.x, self.view.center.y - 20);
scrollLayer.scrollMode = kCAScrollBoth;
[self.view.layer addSublayer:scrollLayer];
UIImage *image = [UIImage imageNamed:@"eclipse32.gif"];
for(int i=0; i<6; i++) {
layer = [CALayer layer];
layer.backgroundColor = [[UIColor blackColor] CGColor];
layer.bounds = CGRectMake(0, 0, 100, 100);
layer.contents = (id)[image CGImage];
layer.position = CGPointMake(layer.bounds.size.width * i, self.view.center.y);
[scrollLayer addSublayer:layer];
}
// [button removeFromSuperview];
// [self.view addSubview:button];
// self.view.userInteractionEnabled = YES;
[image release];
}
The scroll layer shows, the icon is repeated on the layer I have a border around the edge of the screen. Everything is lovely except I can't scroll the icons. I've tried with/without setting scroll mode. I've tried with a single stretched icon that falls off screen. I've tried everything. What am I doing wrong?
