Hi All,
I am stuck again at seemingly obvious point, but I can't figure out
where
In MyView Class , below lines work fine for flipping the layer (but
whenever I try to resize or add a subLayer to it, view flashes for the
reason I don't know)
-(void)awakeFromNib{
drawLayer = [CALayer layer];
drawLayer.backgroundColor = CGColorCreateGenericRGB(1.0f,1.0f,1.0f,
1.0f);
CGAffineTransform transform = CGAffineTransformIdentity;
/* CGAffineTransform transform = CGAffineTransformMake (1.0f,0.0f,
0.0f,-1.0f,0.0f,0.0f); */
transform.d = -1.0f;
drawLayer.affineTransform = transform;
[self setLayer:drawLayer];
[self setWantsLayer:YES];
}
but when I try to check the flag uses CoreAnimation layer in interface
builder for MyView and use below lines
-(void)awakeFromNib
{
drawLayer = [self layer];
drawLayer.backgroundColor = CGColorCreateGenericRGB(1.0f,1.0f,1.0f,
1.0f);
CGAffineTransform transform = CGAffineTransformIdentity;
transform.d = -1.0f;
drawLayer.affineTransform = transform;
}
now I don't see any layer added , if I omit the affineTransform part ,
then view behaves perfectly with no flashes whatsoever but layer isn't
flipped.
Thanks in advance for any help.
