I have a sign in window that implements a simple CAKeyframeAnimation
to perform a shake if the sign in fails using the NSWindow's
animator proxy object.
i.e.
[self setAnimations:[NSDictionary dictionaryWithObject:[self
shakeAnimationWithNumber:4 duration:0.5f vigour:0.03f]
forKey:@"frameOrigin"]];
[[self animator] setFrameOrigin:[self frame].origin];
However, I need to make the app modal for that window, and when I do
the animation doesn't fire (or isn't visible).
Anyone have any idea of what I should be looking for in the
documentation to explain this? Is there some kind of run-loop mode
dependency I am not aware of?
To answer my own question. I took a WAG that this was run-loop issue
and tried this hint:
<http://www.dejal.com/blog/2007/01/cocoa-topics-case-modal-webview>
I switched the opening of the window from runModalForWindow: to
beginModalSessionForWindow: + runModalSession with a tickle of
[[NSRunLoop currentRunLoop] limitDateForMode:NSDefaultRunLoopMode]
each time through the loop.
The shake animation now happens as expected. I have no idea whether
there is a different/better way of handling this but it is working now.
