Hi all,
I've been playing with CA today and encountered some weird problems.
Firstly, I tested setHidden: on an animator on a NSSegmentedView and
it worked fine - it gets faded in/out. Now, all the problems I
encountered happen in another NIB file. I've got the following piece
of code (in a controller):
[self.generalView setHidden:YES];
[self.window setContentView:self.generalView];
[[self.generalView animator] setHidden:NO];
This should produce a fade transition, as long as self.generalView's
superview, or an ancestor view higher up, has wantsLayer == YES.
Does it help if you wrap the un-hide in an explicit NSAnimationContext
begin/end?
[NSAnimationContext beginGrouping];
[[self.generalView animator] setHidden:NO];
[NSAnimationContext endGrouping];
I expect this to animate the view but it doesn't happen - no
animation goes on. I've made sure that all NSView's want layers. I
also noticed some other unusual problems
with the said NIB:
- Animations work on a random basis (CA animations)
A more specific example would help.
- If I attach an outlet to a particular NSPopUpButton, it
disappears. Removing the outlet makes it appear again
The NSPopUpButton disappears? What do you see when you look at the
popup button's state when this has happened? (i.e. What does -
isHiddenOrHasHiddenAncestor report, and frame, superview, etc.?)
Something must be collapsing it, hiding it, removing it from the view
tree, or moving it out of its superview's visibleRect.
I think I'm missing some setup here but I cannot figure out exactly
what it is. The NIB (saved as a XIB) was created from scratch (i.e.,
not included in a project template) but I can't see how this can be
a problem. Any help is greatly appreciated.
