Core Animation action transition: how do it right - cocoa

Question

I make a test project with one view inside of content view of main window. Window have two buttons: appear & disappear. I want animate view appearance when appear button pressed, and animate dissapearance when dissapear button pressed. And I want do this with layer actions.
In other words, I want to make animation every time view added or removed from superview. So, in code I just want to write [parent addSubview:view] or [view removeFromSuperview] and animation should work in that moments. So, Layer Actions seems fits my needs.
Here is app screenshot and source code (XCode 4.6):
Here is what I did to do that:
I create a view that will appear/dissapear and add layer action:
_coloredView = [[ColoredView alloc] initWithFrame:NSMakeRect(0, 0, 200, 200)];
_coloredView.bgColor = [NSColor yellowColor];
_coloredView.wantsLayer = YES;
// making appear transition from left
CATransition *appearTransition = [CATransition animation];
[appearTransition setDuration:2];
[appearTransition setType:kCATransitionPush];
[appearTransition setSubtype:kCATransitionFromLeft];
[_coloredView.layer addAnimation:appearTransition forKey:kCAOnOrderIn];
Then when appear button clicked, I call
[contentView addSubview:self.coloredView];
When disappear clicked, I call:
[self.coloredView removeFromSuperview];
And seems some part of things works. The yellow rectangle appears as it should first time. But, here is list of very strange things:
I should call addAnimation:forKey: every time when button clicked (after view was disappeared), since after first appearing animation will no longer work.
Disappear won't work at all (If I try add code after view initialization or before disappear button pressed)
When I try to add subview through animator, my transition not work - just default fade-in animation shown.
Seems that during movement from left to right some sort of fading works. It's visible when you set duration to bigger value.

Try #"subviews" instead of kCAOnOrderIn
