In my viewDidLoad I have this code which sets up some drawing on a CALayer:
rootLayer = [CALayer layer];
rootLayer.frame = CGRectMake(164, 243, 30, 30);
[self.view.layer addSublayer:rootLayer];
It's positioned properly. Now, I'd like to have it rotate around it's
"registration" point. Adding a background color to the layer I can see that
my drawing uses the top left corner of the layer.
I have this method with only works correctly for portrait, for the others
all i want to do is see it rotate 90ยบ and then I can figure the rest out.
This is rotating the layer but on device rotation, the whole layer is
shifting around. I'd like to lock it down to the original corner:
-
(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration {
if(toInterfaceOrientation == UIInterfaceOrientationPortrait){
rootLayer.transform = CATransform3DMakeRotation(0.0, 0.0, 0.0, 0.0);
} else {
rootLayer.transform = CATransform3DMakeRotation(90.0/180 * M_PI,
0.0, 0.0, 0.0);//rotates but moves down to the left
}
}
