Hi all,
I was playing around with core animation and was wondering if
sending animator to a view, specifically an NSImageView, will it
only manage animation of bounds and size and rotation changes or
can it too be used for changing the contents of the NSImageView? I
am trying to animate the change in the NSImageView, but hence with
no luck.
Hope I'm not mistaking core animation for what it is not :D
Core animation could do this, but it is not possible through
animation proxies. I believe NSAnimation will be the easiest path to
go down._______________________________________________
You could do something almost equivalent with animation proxies by
swapping out subviews. In particular, setup a CATransition on the
superview, then replace your NSImageView with a new instance, already
loaded with an image.
Check out the SlideshowView class of the CocoaSlides example code.
http://developer.apple.com/samplecode/CocoaSlides/index.html
Key lines of code would be something like this to setup:
CIFilter *filter = [CIFilter filterWithName: @"CIDissolveTransition"];
[filter setDefaults];
CATransition *transition = [CATransition animation];
transition.filter = filter;
transition.duration = 0.2;
[mySuperview setAnimations: [NSDictionary dictionaryWithObject:
transition forKey:@"subviews"];
And then animate by doing something like,
[[mySuperview animator] replaceSubview: oldImageView withSubview:
newImageView];_______________________________________________
